prevent corrosion of electrical contacts;
* Never key the microphone unless an antenna or suitable dummy load is
connected 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.
