bristle brush.

detergent soap and warm water. Mix at a ratio of 1 ounce of detergent to at least 4 cups of water.

Do not use other chemical cleaners, sprays, or any petroleum-based products. They may
damage the radio housing, display, knob, and/or button surfaces.
Always follow all of the manufacture’s recommendations when using any cleaning
product/solution. This includes, but is not limited to, ensuring the work area is properly
ventilated and be sure to wear safety glasses or goggles.
Use this cleaning procedure:
1. Turn off radio via the control head’s on/off/volume control.
2. Remove radio’s main power fuse and the control head’s ignition power fuse. Mark the two fuses so
they can be re-installed into their original locations later.
3. To remove excess dust and dirt from the radio equipment, first brush the equipment with a clean dry
soft-bristle brush.
4. Apply the cleaning solution to a soft clean cloth. To prevent excessive vapor concentrations, be sure
the surrounding area is well-ventilated. Do not spray any cleaning product directly on the radio
equipment.
5. Wipe the radio clean with the dampened cloth. Always apply the cleaning solution to a soft clean
cloth, and then use the dampened cloth to wipe the equipment clean.
6. Wipe off the radio equipment with clean damp cloth using mild warm soapy water.
7. Follow-up by wiping the equipment with a clean cloth dampened with only clean warm water.
8. Finish by wiping the equipment dry with clean dry cloth.
