The charger shown above has two slots in which to place a battery. The back slot is for fast charging and the front slot is for slow charging. Only the battery can be inserted in the fast charge slot and the entire transceiver can be inserted in the slow charge slot if desired. Batteries can be charged in both slots at the same time. The operation of the two indi- cators is described in Table 1.

Fast Charging - When a battery is placed in the fast charge slot, fast charging begins as indicated by a steady red indicator. Then when the battery is nearly fully charged, the charger switches to a trickle rate (20- 40 mA) and the indicator turns green. It continues at this rate until the battery is removed from the charger. The temperature must be 0 to +45° C (+32 to +113°F) for rapid charging to occur. Approximate charge time in this slot for a fully discharged battery is 1.5 hours.

NOTE: Occasionally, a fully charged condition may be falsely detected and the trickle mode entered after only a few minutes of rapid charging. To resume normal rapid charging if this occurs, momentarily take the battery out of the slot.

Slow Charging - Batteries placed in the front slot are always charged at the slow rate (100-120 mA). The slow charge indicator turns green when
