Floating/Waterproof: JIS8
Uniden’s MHS050 radio is designed to meet the water proong
standard of JIS8 and will oat in water.
This Means: Protected against the effects of continuous immersion in water.
The MHS050 can withstand immersion in water up to 1.5m depth for 1hr.
Note this is not suitable for scuba diving.
NOTE
The MHS050 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.
After your radio is submerged 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.
