This compact, state-of-the-art device is equipped with many features. INSTALL THE BATTERY Each GMR638 radio uses a NiMH battery pack (not included with GMR638-2) or 4 AAA alkaline batteries (not included). If you use alkaline batteries, we recommend high quality alkaline batteries. To install the NiMH battery pack: 1) Make sure your radio is OFF. 2) Release the battery cover clip, then remove the battery cover. 3) Install the NiMH battery pack into the battery compartment. 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. Note: The charge indicator LEDs will remain on as long as the radios are left in the charger.
