Cobra Electronics 25 LTD ST How SoundTracker Works, Operating Procedure to Transmit

Select the desired channel.

Set the DYNAMIKE control fully clockwise.

Operation (Cont.)

Operating Procedure to Transmit

1. Be sure the operator has read and understands part 95, F.C.C. Rules and Regulations prior to operating the transmitter.

2.

3.

4. The receiver and transmitter are controlled by the press-to-talk switch on the microphone. Press the switch and the transmitter is activated; release switch to receive. When transmitting (on a clear channel), hold the microphone two inches from the mouth and speak clearly in a normal voice.

Be sure the antenna is properly connected to the radio before transmitting. Prolonged transmitting without an antenna, or a poorly matched antenna, could cause damage to the transmitter.

Operating Procedure for Public Address

1. Connect a PA speaker to the PA jack provided on the rear panel.

2. Place PA/CB/ANL switch into the PA position.

3. Depress push-to-talk switch on micÑspeak in normal voice.

4. Adjust PA speaker volume with front panel DYNAMIKE control.

When the Volume control is rotated clockwise, activity on the CB channel will be heard through the PA speaker.

How SoundTracker Works

SOUNDTRACKER SYSTEM

While previous systems only Òblanked outÓ or limited noise in higher sound frequencies, the revolutionary new SoundTracker System actually reduces noise while leaving the signal intact in the reception mode. In the transmission mode, it actually strengthens the signal, providing you with a significant reduction in noise on reception and transmission.

Sound clarity is measured by the ratio of the signal level to the noise level. The higher the signal-to-noise ratio, the better the sound.

HOW SOUNDTRACKER WORKS

On Reception–“Cuts Noise Coming In”

With a normal CB, distant signals fall below the squelch level and are unintelli- gible. With a SoundTracker CB, the noise level is cut by up to 90%, which increases the signal-to-noise ratio and dramatically improves signal clarity. This also allows you to significantly reduce the squelch level, which greatly expands your listening range.

On Transmission–“Strengthens Signals Going Out”

A SoundTracker CB strengthens the transmit signal by more effectively using the available RF power output of the CB. The result is improved transmission signal clarity and an expanded transmission range.
