INSTALL THE BATTERY
GMR4055 and GMR4088 models use NiMH AA rechargeable
batteries (included) or 3 AA alkaline non-rechargeable batteries
(not included). GMR4060 models use Lithium Ion battery packs
(included).
To install the batteries/battery pack:
1. Unscrew and remove the battery compartment cover.
2. Install the batteries/battery pack into the battery compartment. Be

battery level meter icon flashes. Recharge the batteries/
battery pack immediately. If you are using alkaline batteries
(GMR4055 and GMR4088 models only), you must replace the
alkaline batteries in order to continue using the radio.
CHARGING THE RADIO
If using rechargeable batteries/battery packs, two radios can be
charged directly by using the supplied charging cradle. A single
radio can charge using the miniUSB port to connect to a USB
power source. For fastest charging, turn off the radio before
charging.
Warning! To avoid the risk of personal injury or property damage
from fire or electrical shock, only use the Uniden accessories
specifically designated for this product.
Warning! Do not attempt to recharge Alkaline batteries
(GMR4055 and GMR4088 models only).
Using the miniUSB Port
1. Connect the included AC adapter with miniUSB connector cable
to the radio's miniUSB port. Connect the other end to an outlet
that provides USB charging power (NOT to a USB hub).
2. Charge the batteries/battery pack for 16 hours until the battery
indicator either stops flashing (GMR4055 and GMR4088 models
only) or turns off (GMR4060 models only).
Using the Charging Cradle
1. Connect the included AC adapter with USB connector cable to the
charging cradle's miniUSB port. Connect the other end to a
standard 120V AC wall outlet.
2. Set the charging cradle on the desk or tabletop, and place the
radio in the charging cradle with the keypad facing forward.
3. Charge the battery pack for 14 hours. For GMR4055 and
GMR4088 models, the battery indicator is solid and the charger
LEDs turn off. For GMR4060 models, the battery indicator turns
off and the charger LEDs turn off.
Note:
• Use only the supplied battery and AC adapter or approved
accessories from Uniden.
• Charge time may vary depending on the battery life remaining.
• Do not attempt to recharge alkaline batteries (GMR4055 and
GMR4088 models only). Doing so can create a safety hazard or
