32 Getting Started
Charging Your Batteries
Using the Internal Charger
.
Believe it or not, there’s a battery charger built right into 
your phone! Using either the AC or cigarette lighter adapter, 
you can plug the handset directly into a power source to 
charge any attached batteries.
Tip: 
If both a main 
and auxiliary 
battery are 
attached, the 
main will be 
charged to 95% 
before the 
auxiliary is 
charged.
To charge:
1.
Plug the AC adapter 
or cigarette lighter 
adapter into the 
accessory connec-
tor on the bottom 
of your phone as shown, with the release tab facing 
up.
2.
Plug the power adapter into a 110V AC electrical 
outlet. You will hear a beep-tone and you will see 
the battery icon flashing.
Tip: 
You can still 
place and answer 
calls while using 
the internal 
charger. Keep in 
mind that talking 
on the phone 
requires energy, 
so charging will 
take more time.
See “Charge Times” on page 37 for charge times.
