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.
To prevent corrosion of electrical contacts and keep the water resistance,
keep the microphone or the jack connected at all times.
Never press the PTT switch unless an antenna or suitable dummy load is
connected to the antenna receptacle.
Ensure that the input voltage does not exceed the value specified in your
Owner's Manual.
Use only STANDARD HORIZON-approved accessories and replacement
parts.
