Safety  
Your 75-440 handheld transceiver has been carefully designed to give you years of safe, reliable  
performance. As with all electrical equipment, however, there are a few basic precautions you should take  
to avoid hurting yourself or damaging the radio:  
Read the instructions in this handbook carefully. Be sure to save it for future reference.  
Read and follow all warning and instruction labels on the radio itself.  
Do not carry the transceiver by the antenna. This may damage the antenna or antenna terminal.  
Grasp it by its base (not the tip!) when you need to place or remove it.  
Do not keep the radio with the antenna very close to, or touching exposed parts of the body, while  
transmitting. The radio will perform best if the microphone is 5-10 cm away from the mouth and the  
radio is vertical.

To select a channel:  
1) Press the  
key to increase the channel number or the  
key to decrease it.  
Receiving  
Your radio can be programmed to work, channel by channel, in “Open traffic” or “GROUP MODE  
(CTCSS/DCS)”. Group mode prevents other users of a channel from being heard on your radio. See  
“Setting Group Mode Codes” for programming instructions.  
OPEN TRAFFIC: in this case you will hear all communication which will be transmitted on the  
selected channel. When a message is received your squelch will un-mute, you will see the status LED  
glowing green and you will hear the message.  
GROUP MODE:  
CTCSS/DCS (Continuous Tone Code Squelch System / Digital Coded Squelch): are systems  
which use particular TX signaling as an access “key” to work a repeater (encoder) or to unlock the  
party’s signaling sensitive squelch. This last condition allows more radio networks to share the  
same frequency. In this case you will receive only messages coming from parties sending a  
proper TX signaling. During “CTCSS/DCS” operation, the radio may be set-up so that the  
appropriate CTCSS/DCS decoder enables the speaker.  
, CTCSS/DCS If more than one station is transmitting at the same time, this will cause  
interference! Do not transmit if the status LED is glowing. Wait until the channel is clear before  
transmitting.  
Monitor Button  
The Monitor button can enable or disable “GROUP MODE (CTCSS/DCS)” if programmed for that channel.  
1) To enable GROUP MODE. Press and release the“MON” button: “SAT” icon is displayed. A Sub  
Audible Tone mutes your speaker.  
Page. 13  
 
75-440 User manual  
2) To Disable GROUP MODE. Press the “MON” button: “SAT” icon is not displayed. You are now  
working in “Open Traffic”.  
NOTE: if “SAT” icon is never displayed, “CTCSS/DCS” tone is not programmed. “GROUP  
MODE” function is not available. See ‘Setting “Group Mode” codes’.  
3) Press and Hold “MON” button for three seconds, internal squelch will be disabled and your speaker is  
un-muted. Press and release the “MON” button to restore the squelch to normal operating condition.  
Transmitting  
1) Ensure that the channel is not busy otherwise you will create interference.  
2) Press the “PTT” button, the status LED will glow red.  
3) Start talking at a normal voice level at approximately 2.5 inches from the microphone (keep the  
“PTT” button pressed).  
4) When you have finished talking, release the “PTT” button.  
Do not shout! It will not increase the distance you can transmit, but rather will make you heard  
distorted.  
Do not release the “PTT” button before your message is over or start talking before pressing  
PTT”, otherwise your message will be “chopped”.  
A GMRS handheld radio does not normally allow you to talk and receive simultaneously, for this  
reason make your messages short. When you are talking the other parties can not use the channel!  
Use common sense.  
Your radio is programmed with a timeout timer which will automatically turn off the transmitter if  
you talk longer than 90 seconds. In this case release the “PTT” and wait for few seconds, the radio  
TX features will be automatically restored.  
Adjusting Transmit Power  
Your 75-440 can transmit with two power levels according to the distance of your party’s station(s). We do  
recommend, when possible, to use the Low power setting. This will increase the battery life and will  
reduce the risk of interference with other stations not in your radio network that may be sharing the same  
channel with you.  
1) To change the channel's Power Output level from high (2 Watts) to Low (0.5 Watt), or vice versa,  
Press and Hold “FUNC” key for about 2 seconds. A small "LOW" will appear in the lower left corner  
of the display to indicate “Low Power”. High Power has no indicator.  
If the battery icon is "blinking" (Low Battery indication), the Unit will automatically switch to Low  
Power when transmitting in order to help prolong the Battery's operational life. In this case, two  
short beeps will be heard when you press the “PTT” key before the radio transmits.

Scanning channels  
Your 75-440 has three types of scanning available. The most used is Normal Scan. This allows you to  
scan all the channels you have designated in your scan list (see Creating Scan List). The next is scan with  
a Priority channel (channel 1). This scan allows you to monitor channel 1 more often than the other  
channels while scanning (for this scan to work properly you must have at least 6 channels in the scan list).  
The third scan type is Dual Watch. This allows you to scan the priority channel and a channel of your  
choice. You must have more than one channel programmed in the scan list in order for your 75-440 to  
scan them. The advanced scan function of the radio allows optionally looking for carrier or carrier with  
“CTCSS” or “DCS.”  
Activating, Deactivating Normal Scan  
1) Press the “CALL” button +

Reviewing the Scan-List.  
1) Scroll the channel list, channels which show the ““ icon, are in the “SCAN” list.  
2) Select the channel, which is to be added or deleted from the “Scan” list.  
Adding and removing channels from the Scan list is not available during scanning.  
3) Press “CALL” + “MON” button, the “” icon will appear or disappear. (See step 1 above.)  
NOTE: If the Scan List has no channels, a low tone (error beep) will be heard when the CALL”  
+
key is pressed, no channel will be scrolled in the display. At least two channels must be in  
the Scan List for the Unit to be put in the SCAN Mode.  
When a signal is received on a channel, the radio will stop scanning and the speaker will become  
un-muted. When the activity on that channel ceases, the unit will automatically resume scanning.  
If CTCSS/DCS have been previously programmed, the scanning will stop only if the received  
carrier has the correct CTCSS or DCS code for that channel.  
If “PTT” is pressed during scanning, the radio will transmit on the first vacant channel. In case of no  
activity, the Unit will automatically resume scanning.  
Selecting a Priority Channel  
One channel can be assigned as a “Priority Channel”. The scanning will look back at the priority channel  
most frequently. Channel 1 is factory set as the priority channel.  
Current radio version only allows for PC programming of another priority channel.

Battery Packs  
Information on rechargeable batteries  
When the battery pack is new it will not provide 100% of its efficiency. To reach the full battery run  
time you have to “run-in” the battery with at least 3-4 deep charging/discharging cycles. After that  
it will reach its maximum capacity. Please see “Proper charging of battery packs” for further  
details.  
When you properly use the battery pack, you will obtain about 400 charge/discharge cycles (300  
with the optional rapid charger). The battery “run time” will progressively reduce after 2/3 of its life  
(approx.).  
Rechargeable battery packs lose their charge with time if left unused (self-discharge), this is  
normal. A NiMH (Nickel Metal Hydride) battery can reduce 10 to 20% of its stored energy in few  
days.  
Proper charging of battery packs  
1) Ensure that the radio is switched off,  
5) Insert the radio into the cradle as explained in the paragraph “Charging the battery pack”  
6) Wait the necessary time to provide a full charge. If the pack isn’t completely discharged you will need  
less than 8 hours.  
, Do not overcharge the battery: always remember to remove the radio after the necessary time.  
, The battery charger is for indoor use only.  
When possible, charge the battery only when it is fully discharged or, at least, you have used it for  
the major part of the day, otherwise the battery’s “run time” could be temporarily reduced.  
Do not remove the radio before the necessary time, otherwise the battery’s “run time” could be  
temporarily reduced.  
When possible charge battery packs only when they are completely discharged, i.e. when the  
battery icon has no bars inside.  
Do not remove the battery from the charger before the necessary time to provide a full charge.  
Provide at least two deep charge/discharge cycles per month.  
Warnings for battery and chargers use  
Please use these cautions to avoid damaging battery packs or the transceiver:  
, Before using the battery charger carefully read any related warning or caution.  
, Do not short battery terminals: this may cause fire, burns or explosions.  
, Never dispose batteries into fire they may explode causing fire, burns or explosions. Strictly  
follow any disposal regulation of your Country.  
Page. 20  
 
75-440 User manual  
, Use only authorized batteries and chargers. The use of non-authorized accessories may cause  
burns, fire or explosions causing serious damages to the radio/battery or serious injuries to  
people.  
, Battery chargers are for indoor use only.  
, Be certain that your power source matches the rating listed for the supplied battery charger  
(AC Adapter). If you are not sure, check with your dealer or with your local power company.  
, To avoid damaging the power cable of the battery charger, do not put anything on it or place it  
where it will be walked on. Insert the plug in socket provided with earth connection.  
, Avoid strong shocks. Do not use the charger if it received a strong shock, has fallen down or it  
appears damaged; immediately contact an authorized service station.  
, Never try to disassemble or service the charger by yourself. Always contact your local dealer  
for assistance.  
, To reduce the risk of electric shocks disconnect the plug before providing any cleaning or  
maintenance. Grasp the plug (not the cable) to remove the plug from the socket. The use of  
non-suitable extension can cause fire or electric shocks.  
, Do not expose batteries directly to temperatures below -20°C (-4°F) or greater than 35°C (95°F)  
during their use and do not charge them outside the range of +5 to +55°C.  
Radio maintenance  
Cleaning battery packs  
Wipe the battery contacts with a clean and lint free cloth to remove dirt, grease or any other material that  
may prevent a good electrical contact. If contacts are very dirty you can also wipe them using a soft pencil  
rubber (not hard erasers for ink!). If you feel that battery contacts aren’t still working properly, please  
contact your authorized dealer.  
, Do not use liquid, alcohol or aerosol cleaners.  
Cleaning the radio  
Wipe the radio with a clean and lint free cloth to remove dust. If it is very dirty, you can use a damp  
(slightly moistened with water) cloth.  
, Do not use liquid, alcohol or aerosol cleaners.  
If you normally use your radio in dusty or hard environments, we do recommend using the optional  
carrying case. Please see “Optional accessories”.  
Connectors  
When the connectors are not being used, they should be fitted with the supplied cover caps.  
, Only suitable accessories must be connected to the related connectors.  
Page. 21  
 
75-440 User manual  
Optional accessories  
These optional accessories can be used to improve the transceiver’s performances:  
Spare battery pack number 81B02. It extends the duty time.  
Rapid charger number 18-388. Recharges the battery packs in 1 hour and provides trickle charge  
when they reached their full charge.  
Carrying case. Protects your radio against small shocks and scratches the best for use in hard  
environments.  
WARNING, RF exposure  
Your wireless hand-held portable transceiver contains a low power transmitter. When the Push-to-Talk  
(PTT) button is pressed sends out radio frequency (RF) signals. The device is authorized to operate at a  
duty cycle factor not to exceed 50%. In august 1996, the Federal Communications Commissions (FCC)  
adopted RF exposure guidelines with safety levels for hand-held wireless devices. The FCC has issued  
the following warning,  
To maintain compliance with the FCC’s RF exposure guidelines, this transmitter and its antenna must  
maintain a separation distance of at least 2 inches (5 centimeters) from your face. Speak in a normal  
voice, with the antenna pointed up and away from the head at the required separation distance. The belt  
clip is for storage only. DO NOT TRANSMIT WHILE USING THE BELT CLIP. To transmit, hold the device  
away from your body and ensure the antenna is at least 2 inches (5 centimeters) from your body when  
transmitting.  
Microphone connector  
The microphone connector is designed for the connection of two basic accessories (not supplied as  
standard):  
External speaker/microphone: Allows you to use the radio secured to your belt by means of the  
supplied belt clip.  
Headset with built-in microphone: Will additionally add the VOX facility, For further details please  
see “Hands free transmission (VOX)”.  
Any kind of accessory for the above stated purposes can be connected to the microphone connector,  
provided that they meet the following requirements:  
Jack connectors for Speaker (SPK) and Microphone (MIC) must be respectively standard type 3.5 mm  
and 2.5 mm. and connected as follows:  
MicGND
