Battery recharge - How to use the desktop charger

Insert the AC plug into the 240V socket. The charger’s led starts blinking,
indicating that it is in stand-by mode.
The desktop charger can charge either the complete radio or the battery pack
only.
Insert the transceiver (swtiched o) or the battery pack into the proper char­ger cradles.
The led turns on red indicating that the battery pack is being charged. Once
the led turns green, the battery pack is fully charged.
A complete recharge requires 5/6 hours, depending on the battery level.

NOTE: If the radio is fully discharged, the red led will be blinking for 10/20 minutes,
then it will be steady red. Once the led turns green, the battery is totally charged.
