"CONNECTING THE LOCKING MIC PLUG
Your Transceiver features a new locking microphone connector. This
a insures that you won't accidentally pull out or loosen the plug connection
(when extending the MIC cable while moving about).
To connect the Mic plug:
Press the small tab on the side and insert plug into jack, taking care to
align the plug and jack properly. See Figure 1A.

To release the Mic plug:
You must press the small tab on the side, push plug in to release lock and
then pull out. See Figure 1B.
Note: To hear receiver's sound, you must have the Mic connected.
TO GET THE MOST OUT OF YOUR TRANSCEIVER...
We've provided a few extra features that will enhance your operation.
The ANL switch adds an Automatic Noise Limiter circuit which helps to
reduce or eliminate low-level impulse-type external noise. If you don’t
need this circuitry, leave switch in the OUT position.
The S/RF Meter gives you a relative indication of RF output power when
you are transmitting (upper scale — any reading in the red area means
you have full legal output). When receiving, the meter shows the relative
strength of the incoming signal (lower scale — in ‘’S”’ units).
The Modulation LED will light up when you transmit. Degree of
brilliance will vary with your voice level. It will be at maximum brilliance
when you achieve 100% modulation.
A Remote External Speaker connected to the EXT SPKR jack on the
back will give you added versatility. When you plug a miniature jack into
this connector, the internal speaker will be disconnected. Radio Shack
sells a number of fine speakers for Remote/Extension CB use.
