95 General Information
Several conditions determine the distance that your radio will transmit a
clear data/voice communication. The following list describes many conditions and
their typical affect on your radio's transmitting distance.
Condition Description
radio's power more power
radio's frequency lower frequency (VHF compared to UHF)
radio's tuning properly tuned radio (on frequency, more power)
stormy weather adverse atmospheric conditions
at sea better ground plane (clearer line-of-sight)
city large/tall buildings (interference problems)
in a building structural boundaries (interference problems)
on a tall building's roof less interference (clearer line-of-sight)
in a subway below ground level (interference problems)
on top of a hill less interference (clearer line-of-sight)
intervening hills more interference (no line-of-sight)
inside a vehicle metal structure (interference problems)
Cleaning
Clean external surfaces of the radio with a mild detergent and a stiff, non-
metallic, short-bristled brush. A suitable detergent solution may be mixed by
adding one teaspoon of mild dishwashing detergent to one gallon of water (0.5%
solution). Apply the detergent solution sparingly with the brush, being careful not
to allow excess detergent to remain entrapped near connectors and controls or
in cracks and crevices. Do not submerse the radio in the detergent solution. Dry
the radio thoroughly with a soft, lint-free cloth.
Clean all battery contacts with a lint-free cloth to remove dirt, grease, or
other foreign material that may prevent good electrical connections.
Handling
Avoid physical abuse; do not pound, dr op, or throw the radio
unnecessarily. Do not carry the radio by the antenna.
Avoid subjecting the radio to an excess of liquids. Never allow the radio
to become submersed.
Avoid subjecting the radio to corrosives, solvents, or spirits.
Do not disassemble the radio in any way. Keep the connector cover in place
