Congratulations on your purchase of the Uniden
GMR2872-2CK/GMR2875-2CK (General Mobile
Radio Service) waterproof radio. This lightweight,
palm-sized, radio is a state-of-the-art device,
equipped with many valuable features. Use it at
sporting events, to stay in contact with family and
friends, hiking, skiing, outdoors, or in a
neighborhood watch for vital communication - even

standards, which means the radio can be

there is still water remaining in and around the
speaker and microphone. Just shake the radio to
clear excess water, and the sound should return to
normal.
Note:
If your radio is exposed to salt water, clean
your radio thoroughly with fresh water, and dry it
before turning it on.
