REPLACING THE FUSE

The TRC-501’s 2-amp and 1-amp
fuses help protect your CB from pow-
er surges and short circuits.

• If the black wire’s fuse is blown,

replace it with a 2-amp, fast-act-
ing glass fuse (Cat. No. 270-
1007).

• If the orange wire’s fuse is

blown, replace it with a 1-amp,
fast-acting glass fuse (Cat. No.
270-1005).

Follow these steps to check and re-
place each fuse, if necessary.

1. Make sure the power source

and CB are both turned off.

2. To open the fuse holder, push

the fuse holder ends together,
then turn either end counter-
clockwise and release it.

3. If the fuse is blown, replace it. 

Caution: Make sure you replace
the fuse only with another fuse
of the same type and rating.

4. To close the fuse holder, push

the fuse holder ends together,
then turn either end clockwise.
