9、s 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 exc

10、eed 16 VDC or fall below 11 VDC. (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, continu

11、ed 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

12、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. 7.2 FUSE REPLACEMENT To protect the equipment from serious damage, a fuse is provided on the po

13、wer supply lines. The fuse protect against overvoltage / 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 7A for RCI-2950 DX and 20A for RCI-2970 DX should not be used, since it may per

14、manently damage the equipment. Damage due to overfusing is not covered by the warranty. - 23 - RCI-2950 DX RCI-2970 DX CHAPTER 8 DIAGRAMS & PARTS LIST 8.0 GENERAL Information on most electrical and mechanical parts is included in the parts list.
