MAINTENANCE
5.0 PRECAUTIONS
The inherent quality of the solid-state components used in this transceiver will provide many years of
continuous use. Taking the following precautions will prevent damage to the transceiver.
(i) Never key the transmitter unless an antenna or suitable dummy load is connected to the antenna
receptacle.
(ii) Ensure that the input voltage does not exceed 16 VDC or fall below 11 VDC.
(iii) During alignment, do not transmit for more than 10 seconds at a time. Transmitting over long
periods can cause heat built-up and cause transmitter damage.
5.1 PERIODIC INSPECTION
This unit is aligned at the factory to deliver maximum performance. However, continued performance
cannot be expected without periodic inspection and maintenance. Important points to be checked
regularly are as follows;
Check Item Action
Whip antenna
(option)
If cracked or broken, replace it.
Coaxial cable If sheath is cracked, seal with
vinyl tape. If immersed with
water, install new coaxial cable.
Coaxial & power
plug connections
If loosened, reconnect. If
corroded, clean contacts.
Battery connection If corroded, clean power
terminals.
Ground terminal If corroded, clean terminal.
5.2 FUSE REPLACEMENT
To protect the equipment from serious damage, a fuse is provided on the power supply lines. The fuse
protect against overvoltage / reverse polarity and internal fault of the equipment. If the fuse has blown,
first find out the cause of the trouble before replacing it. A fuse rated for more than the transceiver
requirement should not be used, since it may permanently damage the equipment. Damage due to
overfusing is not covered by the warranty.
