7.0 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.
(1) Never key the transmitter unless an antenna or suitable dummy load is connected to the antenna
receptacle.
(2) Ensure that the input voltage does not exceed 110 V AC.
(3) 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.

7.1 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

7.2 FUSE REPLACEMENT

To protect the equipment from serious damage, a fuse is provided on the power supply lines. The fuse
protect against over voltage / reverse polarity or 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 over
fusing is not covered by the warranty.
