Cleaning Your Radio
To clean the external surfaces of your radio:
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, short-
bristled 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.
• Do not submerge the radio as this results in
damage to the radio.
• If water is observed on the battery contact area,
dry and clean the radio battery contacts before
attaching a battery to the radio. Otherwise, the
water could short-circuit the radio.
• If water is observed on the speaker grill area,
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.
• 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.
