Maintenance and Adjustment
Your COBRA CB transceiver is specifically
designed for the environment encountered in
mobile installations.The use of all solid state cir-
cuitry and its light weight result in high reliabili-
ty.Should a failure occur,however,review the fol-
lowing, then if necessary,replace parts only with
identical parts. Do not substitute.
1 . Check connections to the source of power and
make sure it is the 13.8 VDC required to oper-
ate your radio.
2 . Check the fuses in the DC power cord.The
main power lead (red ) has a 2 amp 3AG type
fuse in its holder.Use only the above specified
type and size fuse for maximum protection.
Failure to do so will void the warranty.
3 . Ma ke ce rtain the microphone is pro pe rl y
plugged in.
4 . Make certain the antenna is properly assem-
bled and connected.
If you are unable to correct the problem, refer to
the SERVICE INSTRUCTIONS at the end of this
manual for the correct procedure for warranty
and post-warranty service from COBRA.
