59 General Information
Transmitting Distance
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.
radio's power more power longer distance
radio's tuning properly tuned radio (on frequency, more power) longer distance
stormy weather adverse atmospheric conditions shorter distance
at sea better ground plane (clearer line-of-sight) longer distance
city large/tall buildings (interference problems) shorter distance
in a building structural boundaries (interference problems) shorter distance
on a tall building's roof less interference (clearer line-of-sight) longer distance
in a subway below ground level (interference problems) shorter distance
on top of a hill less interference (clear line-of-sight) longer distance
intervening hills more interference (no line-of-sight) shorter distance
inside a vehicle metal structure (interference problems) shorter distance
Radio Care
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
• Do not handle the radio roughly; do not pound, drop, or throw the radio.
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.
CAUTION
Clean the radio with the recommended solution only. Cleaning the radio
with solvents or spirits may be harmful and permanently damage the
radio housing.
Do not disassemble the radio in any way. Keep the connector cover in place
until ready to use the accessory connector. Replace the cover immediately after the
accessory has been disconnected.
