120  Charging and caring for batteries

continue while the ignition is off, and consider what 

effect this might have on the vehicle battery.

To check, place the battery in the charger, and switch off 

the vehicle ignition:

■

If no charger LED stays lit, the charger will resume 

charging only when the ignition is switched on 

again. Minimal charger standby power will be drawn 

from the vehicle battery until then.

■

If a charger LED stays lit, the charger will continue 

to charge the radio battery even while the ignition is 

off, and will continue to draw power from the vehicle 

battery. Once the battery is charged, the charger 

draws minimal current and has little effect on a 

healthy vehicle battery.

Receiving and making calls while charging

Applies to desktop charger and multicharger only.

Notice  For best charging performance, switch off the 

radio before placing it in the charger.

You can receive or make a call while the radio is in the 

charger, but your radio performance may be degraded. 

If you do remove the radio from the charger to answer a 

call, the call will not be disrupted.

Removing the radio from the charger to make or receive 

a call ends the charging process. Charging safely 

recommences when the radio is reinserted into the 

charger.

If a radio was turned on while being charged, the battery 

indicator may not be accurate when the radio is initially 

removed from the charger. After a few seconds, the 

battery indicator is updated to display the amount of 

charge available in the battery.
