2.0 INTRODUCTION
This section explains the basic operating procedures for the SS-3900EGHP Amateur 10 meter mobile
transceiver.
2.1 CONTROL AND CONNECTIONS
2.1.1 FRONT PANEL
Refer to the above Figure 2-1 for the location of the following controls.
1. ON/OFF VOLUME CONTROL
This knob controls the volume and power to the radio. To turn radio on, rotate the knob clockwise.
Turning the knob further will increase the volume of the receiver.
2. SQUELCH CONTROL
This knob is used to eliminate background noise being heard through the receiver, which can be
disturbing when no transmissions are being heard through the receiver. To use this feature, turn the
knob fully counterclockwise and then turn clockwise slowly until the background noise is just
eliminated. Further clockwise rotation will increase the threshold level which a signal must overcome
in order to be heard. Only strong signals will be heard at a maximum clockwise setting.
3. MIC GAIN CONTROL
Adjusts the microphone gain in the transmit modes. This controls the gain to the extent that full talk
power is available several inches away from the microphone.
