The radio with antenna attached properly is
designed to be submersible to a maximum depth
of 2 meters (6.56 feet) and a maximum
submersion time of 2 hours. Exceeding either
maximum limit or use without antenna may result
in damage to the radio.
If the radio battery contact area has been
submerged in water, dry and clean the radio
battery contacts before attaching a battery to the
radio. Otherwise, the water could short-circuit the
radio.
If the radio has been submerged in water, shake
the radio well so that any water that may be
trapped inside the speaker grille and microphone
port can be removed. Otherwise, the water will
decrease the audio quality of the radio.
If water is observed on the vent port of radio
casting, dry the vent port. Otherwise, the water
will block the vent port and prevent pressure
equalizing of the radio that could affect the radio
overall performance.
Do not disassemble the radio. This could
damage radio seals and result in leak paths into
the radio. Any radio maintenance should be
performed only by a qualified radio technician.

Cleaning Your Radio

CAUTION:
Do not use solvents to clean your radio as most
chemicals may permanently damage the radio
housing and textures.
Do not submerge the radio in the detergent
solution.
To clean the external surfaces of your radio, follow the
procedure described next.
1 Combine one teaspoon of mild dishwashing
detergent to one gallon of water (0.5% solution).
2 Apply the solution sparingly with a stiff, non-metallic,
shortbristled brush, making sure excess detergent
does not get entrapped near the connectors, controls
or crevices. Dry the radio thoroughly with a soft, lint-
free cloth.
3 Clean battery contacts with a lint-free cloth to
remove dirt or grease.
