An LED is located on the main body of the adaptor to indicate
that it is correctly inserted into the cigarette lighter socket
and that DC is applied. The Travel Charger monitors the
battery feedback line (pin 4) on the external connector of the
phone to provide the required supply voltage.
1. MODEL COMPLEMENT
One version covers all normal vehicle applications:
Cigarette Lighter Adaptor/Charger SYN4241
2. OPERATION
A green LED on the body indicates DC power is applied.
When the phone is attached to a charging device, the battery
icon in the phone’s display flashes to indicate charging is
taking place. The battery icon bars indicate the approximate
state of charge; three bars indicating a charge capacity of
90% or more. When attached to a charger, the display shows
a flashing battery and battery level even if the phone is
switched off.
3. MAINTENANCE
A 2.0 A glass tube fuse is located in the tip of the adaptor.
Unscrew the tip to gain access if suspect. Apart from the fuse,
the adaptor is considered non-serviceable. If it becomes
faulty, it should be replaced with a new one.
