8. MAINTENANCE
8.1 GENERAL
The inherent quality of the solid-state components in STANDARD HORIZON
radios will provide many years of continuous use. Take the following precau-
tions to prevent damage to the radio.
y
To prevent corrosion of electrical contacts and keep the water resistance,
keep the microphone connected or the jack covered at all times.
y
Never key the transmitter unless an antenna or suitable dummy load is
connected to the antenna receptacle.
y
Ensure that the input voltage does not exceed the value specified in your
Owner’s Manual.
y
Use only STANDARD HORIZON-approved accessories and replacement
parts.
