 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 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, 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.  
7.2 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 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 permanently damage the equipment. 
Damage due to overfusing is not covered by the warranty.
