Your package contains two radios, 6 AA rechargeable NiMH 

batteries (GMR4055 models) or 2 Li-Ion battery packs 

(GMR4060 models), one charging cradle, one AC adapter 

with single miniUSB connector cable, two belt clips, and this 

reference guide. The GMR4055-2CKHS and GMR4060-2CKHS 

also include two VOX earbuds. To order Uniden accessories, visit 

our web site at www.uniden.com or call 1-800-554-3988 during 

regular business hours. Use only Uniden accessories (AC adapter 

with microUSB plug).

The radio operates on the General Mobile Radio Service (GMRS) 

frequencies when using Channels 1-7 and channels 15-22. You 

must have a GMRS license issued by the Federal 

Communications Commission to legally use these channels. For 

licensing information and application forms, visit the FCC online at: 

www.fcc.gov/wtb/uls or call the FCC hotline at 1-800-418-3676. If 

you have any questions, you can contact the FCC direct at 1-888-

225-5322.  No license is required for operation on channels 8-14 

or operation on any channel in Canada.

GMR4055 models use NiMH AA rechargeable batteries (included) 

or 3 AA alkaline non-rechargeable batteries (not included). 

GMR4060 models use Lithium Ion battery packs.
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 

certain to follow the instructions written on the label on the battery 

pack. Installing the batteries/battery pack incorrectly will prevent 

the unit from operating.

3.  Replace and screw in the battery compartment cover.

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 

 flashes. Recharge the batteries/

battery pack immediately. If you are using alkaline batteries 
(GMR4055 models only)

, you must replace the alkaline batteries in 

order to continue using 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 models only).

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 stops flashing.

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.  Make sure that the LED illuminates. Charge the battery pack for 

16 hours and remove the radio from the charging cradle after the 

charging cradle 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 models 

only). Doing so can create a safety hazard or damage the radio.

•  The battery must be installed for the unit to operate, even if the unit 

is also connected to external power.

•  If battery power is low, you cannot operate the radio even using 

external power. Allow the batteries to charge before using. If you try 

to transmit while power is low, the radio will automatically turn off.

GMR4055-2CKHS and GMR4060-2CKHS come with VOX
