INSTALL THE BATTERY Each GMR638 radio uses a NiMH battery pack (not included with GMR638-2) or 4 AAA alkaline batteries (not included).

Be certain to follow the instruction written on the label on the battery pack. Installing the battery pack incorrectly will prevent the unit from operating. 4) Align the battery cover tabs with the GMR638 tab holes then replace the cover clip. Note: Always make sure your battery pack is fully discharged before recharging to prolong the life of the battery pack. The LED will illuminate while the radio is in the charging cradle. BATTERY LEVEL AND LOW BATTERY ALERT This unit has a battery level meter on the display to indicate the status of the batteries. When the battery in the unit is low, the battery level meter icon will flash.
