4.Transmitting and receiving.

5.Accessing the 16/9 priority channels.

6.Selecting a channel.

7.Selecting high/low power.

8.Locking the keypad.

9.Selecting a weather channel.

10.Adding channels to memory.

11.Scanning.

12.Accessing channels saved to memory.

13.Using the monitor modes.

14.Resetting the radio.

1. Turning the Power On/Off

Use the PWR/VOL knob to turn the radio on, and once on, to adjust the volume as well.

To turn on the radio:

1.Rotate the PWR/VOL knob to turn the radio on or off. The knob will make a clicking noise when you have turned the radio on.

2.Once on, rotate the PWR/VOL knob further to adjust the volume.

2.Adjusting Squelch

Squelch is used to eliminate static and background noise in between transmissions, and allows for silent operation of the radio until a transmission is received. If Squelch is set too high, only the strongest transmissions can be heard, and if it is set too low, intermittent static and noise may be annoying. Squelch is controlled by the SQ knob located on the top of the radio.

To set Squelch:

1.Turn the SQ knob counter-clockwise as far as it will go. You will hear a lot of static.

2.Then turn the SQ knob clockwise until the static stops; this is the correct position for the SQ knob.
