Licence and in New Zealand by MED General User Licence

Floating/Waterproof: JIS7
Uniden’s UH820SX-NB radio is designed to meet the water proong standard
of JIS7 and will oat in water.
This Means: Protected against the effects of immersion in water up to 1m
depth for 30 minutes.
NOTE
The UH820SX-NB will only meet this rating if fully assembled
and all rubber seals are well maintained and correctly tted.
This means that the carabiner clip is not connected and the
battery cover securely fastened.
If your radio is immersed in water, you might notice that the sound is
distorted. This is because 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.
