1. Remove the battery cover by sliding it firmly downwards.
2. Following the polarity diagram inside the battery compartment, insert the batteries.
3. Replace the battery cover.
IMPORTANT!
Ensure that the batteries are installed correctly. Reversing the polarity may damage the unit.
Do not mix old and new batteries.
Do not mix alkaline, standard (carbon-zinc) or rechargeable Ni-MH batteries.
Battery disposal
Depleted batteries need to be disposed of in a way to not damage the environment. Check your
local phone directory for recycling sites.
Automatic Power Saver Mode
Your ATT650/655 has a unique circuit designed to dramatically extend the life of its batteries.
After 6 seconds of inactivity, the ATT650/655 will switch to Power Saver Mode. While in
Power Saver Mode, the transceiver will remain ready to receive any incoming transmissions.
It is automatic and no icon appears on the LCD display.
Battery charging
Safe and approved battery charging requires the use of Nickel Metal Hydride – NiMH
batteries exclusively and an approved Wall Battery Charger (Part number 702520)
supplied by KNG America. The use of other types of rechargeable batteries including
rechargeable Alkaline batteries is not recommended and will void the warranty. Non-
approved batteries could potentially pose a safety risk also.
Warning
: Do not attempt to charge depleted non-rechargeable Alkaline or standard
( carbon-zinc) batteries as this could present a potential safety risk.
Name brand NiMH batteries including Energizer, Rayovac, Duracell, and Panasonic
AAA 1.2 volt 650 mAh or higher capacity will perform well when used with the
approved trickle Battery Charger.
Operating tip:
The use of rechargeable batteries results in reduced performance due to lower
battery voltage. For intermittent use, regular disposable Alkaline or standard carbon-zinc
batteries will perform well and offer a good cost effective solution. Be sure to remove the
batteries should the ATT650/655 series GMRS transceiver not be used for several weeks or
months to prevent possible damage from a leaking battery.
Battery Charging Procedure:
Follow the procedure as outlined above for installing 4 AAA NiMH rechargeable batteries.
Insert the charger (702520) plug into the jack after lifting up the lower end of the rubber cover over the
Headset/Charger jack on the antenna side of the transceiver’s Headset/Charger jack.
Plug the Charger into a 110 Volt AC 50/60Hz outlet. The batteries should be fully charged in
approximately 15 hours.
Make sure the ATT650/655 series transceiver is turned off or battery charging time will be significantly
increased.
