the keypad lock function. This function locks only the channel selector,
quick up/quick down buttons, AM/FM button and scan button. Other
buttons and selectors work normal.

7) AM/FM and LCR Button

When the transceiver is used in UK, UE, or EC frequency
band modes, this button activates or deactivates Las
Channel Recall function. In all other modes (where national
regulations permit this), this button allows user to switch
between AM and FM modes by momentarily pressing this button.

8) CB/PA Selector

This selector should be on CB location in order to operate
the CB transceiver. To make a public announcement, the PA
can be selected. In this case, only the PTT button works and
you can speak through the PA speakers.

9) ANL/OFF Selector

By selecting the ANL location, the transceiver can reduce
such impulsive noise as generated by engine of your vehicle
or external sources. This works only when the transceiver is
in AM mode.
10) Local/DX Selector
To receive weak signals, locate the selector on the DX
position. While the transceiver is in the location where
the signal is very strong, locate the selector on the Local
position. This gives attenuation to get better audio sound.
