SLIDE INDICATOR
The battery has a slideable indicator which you
can use to tell an empty battery from a charged
battery. Slide the indicator to the left if the battery is
empty, to the right if the battery is charged.
If you are uncertain of the state of charge of a
battery, you can attach the battery to the radio. If the
radio does not come on when the O (Power) key is
pressed, the battery is probably empty.
RECHARGING
Avoid recharging a battery before the low
battery alarm has been issued, unless a Smart
Charging Accessory is used.
Never recharge a battery when the ambient
temperature is below 10
°
C or 50
°
F, or above 40
°
C or
105
°
F.
Using Rapid Multi-Charger
The charger will not charge if the ambient
temperature is below 25
°
F or above 105
°
F or if the
battery voltage is below 3 V.
1. Plug the AC converter into an AC outlet.
2. Position the converter cable connector so that it
fits in the jack on the end of the charger and
push it in. As the connector makes contact, the
arrow-shaped LEDs on the charger’s face flash
yellow.
