15 MAINTENANCE
The inherent quality of the solid-state components used in this transceiver will
provide many years of continuous use. Taking the following precautions will pre-
vent damage to the transceiver.
• Keep the microphone connected or the jack covered at all times to prevent
corrosion of electrical contacts;
• Never key the microphone unless an antenna or suitable dummy load is con-
nected to the transceiver.
• Ensure that the supply voltage to the transceiver does not exceed 16 VDC or
fall below 11 VDC.
• Use only STANDARD HORIZON-approved accessories and replacement parts.
In the unlikely event of serious problems, please contact your Dealer or our repair
facility. Address and phone numbers for this facility, as well as warranty informa-
tion, are contained in section “17 WARRANTY.”
