CONNECTING AN 
EXTERNAL SPEAKER
You can connect your transceiver to an
external CB speaker, so you can hear
an incoming call when you are outside
your vehicle.
The external speaker you use with the
transceiver should have an impedance
of 8 ohms and be able to handle 3 to 10
watts of power. The speaker cable must
have a 
1
/
8
-inch (3.5-mm) plug. Your local
RadioShack store carries a variety of
speakers and cables to meet your
needs.
To connect the external speaker to the
transceiver, insert the speaker cable’s
plug into the 
EXT SPEAKER 
jack on the
back of the CB.
Note:
 When you connect an external
speaker, the CB’s internal speaker dis-
connects.
USING VEHICLE BATTERY 
POWER
Follow these steps to connect the trans-
ceiver to vehicle battery power.
1. Connect the red wire (with the in-
line fuse holder) on the back of the
transceiver to a point in your vehi-
cle’s fuse block that has power only
when the ignition is in the ACC
(accessory) or ON position.
2. Connect the black wire to a metal
part of the vehicle’s frame (chassis
ground).
Caution: 
Do not connect the black
wire to a non-metallic (plastic) part,
or to any part insulated from the
vehicle’s chassis by a non-metallic
part.
