- 23 - Figure 6-2 Receiver test setup RCI-2985DX RCI-2995 DX CHAPTER 7 MAINTENANCE 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.
- 24 - (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 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. Ground terminal If corroded, clean terminal. 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.
