This control is used to cut off or eliminate receiver background noise in the absence of an incoming signal. For maximum receiver sensitivity it is desired that the control be adjusted only to the point where the receiver background noise or ambient background noise is eliminated. This will require the incoming signal to be slightly stronger than the average receiver noise. Further clockwise rotation will increase the threshold level which a signal must overcome in order to be heard. This controls the gain to the extent that full talk power is available several inches away from the microphone. In the Public Address (PA) mode, the control functions as the volume control. NOTE: The Weather Alert Tone can be completely turned off by positioning this selector in the off location. 12. Press-To-Talk Microphone Both the receiver and transmitter are controlled by the Press-to-Talk switch on the microphone. Press the switch and the transmitter is activated; release the switch to receive. When transmitting, hold the microphone two inches from the mouth and speak clearly in a normal voice. The microphone provided with your radio is a detachable low-impedance dynamic type. The radio will not transmit in the Weatherband mode even though pressing the microphone switch will cause the red TX LED to illuminate.

Rotate SQUELCH CONTROL counterclockwise until incoming signal is heard. SoundTracker system allows you to reduce unwanted background noise (static) and increase the signal for better reception.

PUBLIC ADDRESS: An external 8-ohm 4. 0 watt PA speaker may be connected to the PA Speaker Jack when this unit is used as a public address system. The speaker should be directed away from the microphone to prevent acoustic feed-back. Physical separation or isolation of the microphone and speaker must be employed when operating the PA at high output levels. EXTERNAL SPEAKER: The External Speaker Jack is used for remote receiver monitoring.
