12. Q.DN (Quick Down) Key
This key allows fast selection of the operating channel downward. Each time this key is pressed, the channel number
moves down by 10 channels.
13. CHANNEL Selector
This knob selects the channel number, by one channel steps. The knob may be turned clockwise to select channels
upward or counter clockwise to select channels downward.
14. EMG (Emergency Channels) Key
This key allows quick access to one of the two pre-programmed emergency channels (CH9 or CH19). Each time this key is
pressed, radio will select CH9, then CH19, then again the normal operating channel. When one of the emergency channels
is selected, the EMG icon (E) will appear on the LCD display. The operating mode (AM or FM) for the emergency channels
is factory pre-programmed as per the following table.

15. ESP (Electronic Speech Processor) Key
The ESP (Electronic Speech Processor) is an exclusive advanced feature in some of the new INTEK mobile CB radios.
ESP means Electronic Speech Processor, in other words electronic modulation processor. This microprocessor
controlled audio device is also called COMPANDER (Compressor-Expander), it works as a modulation compressor in
transmission and as a modulation expander is receive mode. The ESP allows to obtain a stronger, cleaner and clearer
audio signal and it is a great help in noisy areas, in case of long distance communication or with weak signals. The
efficiency of ESP is even greater when communicating with other radios having the same system. To enable or disable
the ESP function, press the ESP key. When the ESP function is enabled, the ESP icon (F) appears on the LCD display.

16. MIC GAIN Control
This transceiver uses a high quality dynamic microphone. The microphone gain is adjustable with the MIC GAIN control.
By turning the knob clockwise, the microphone gain is increased.
17. Q.UP (Quick UP) Key
This key allows fast selection of the operating channel upward. Each time this key is pressed, the channel number
moves up by 10 channels.
18. RF GAIN Control
This transceiver uses a high sensitivity and selectivity receiver circuit. The receiver gain is adjustable with the RF GAIN
control. By turning the knob clockwise, the receiver gain is increased. It is convenient to reduce the receiver gain in case
of very strong signals from local stations and to increase it in case of weak signals or long distance communications.
