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.
8.2 REPLACEMENT PARTS
Occasionally an owner needs a replacement part. Items can be ordered from
our Parts Department by writing or calling (in USA or Canada), or Standard
