CHARGING THE OPTIONAL BATTERY PACK
Your GXT444 is equipped for using an optional rechargeable NiMH battery pack (not included) which can
be recharged using a desktop charger (not included). Initial charge time is 24 hours with a charge time of
8-12 hours thereafter. For maximum battery life, we recommend charging the battery pack when the low
battery icon comes on. Remove the radios from the charger when the charge time expires.
To charge Using a Desktop Charger:
1. Place the rechargeable battery packs in the radios.
2. Connect the AC adapter into an AC wall outlet.
3. Insert the AC adapter plug (or DC Cigarette Lighter adapter if charging in vehicle) into the desktop
charger jack.
4. Place the units into the desktop charger slot and note that the LED indicator with RED color will light
up, indicating charging function. The LED indicator will change to GREEN color once the battery
pack is fully charged.
