4.1 Turning the Power ON and OFF

Turn the PWR/VOL knob clockwise until it clicks.

When the unit powers up in Normal mode it:

1.Beeps, illuminates the backlight at full brightness, and displays all seg- ments and indicators for 2 seconds.

2.Displays the software version number on the dot matrix display.

3.Recalls the last CH number, TX power settings and operation mode. If no last-used setting data exists, goes to CH 16 and high TX Power.

When GPS Data is available, extended position data is also displayed with the offset time on the dot matrix display. This information will be displayed when display option for the position and time is enabled on the Menu. See Section 6.6.

To turn the unit OFF, rotate the Volume knob completely counterclockwise until it clicks.

4.2 Setting the Volume

Adjust the PWR/VOL knob to control the loudspeaker volume level. Turn clockwise to increase the volume; counterclockwise to decrease the volume.

Note: Key press beep volume is also controlled by the VOL level.

4.3 Setting the Squelch

The Squelch circuit sets the threshold for cutting off the receiver when the signal is too weak for reception of anything but noise.

To properly set the squelch, rotate the SQ knob counterclockwise until audio is heard. Then rotate clockwise until background noise disappears.

4.4 Setting the Power Output

The choice of power output is dependent upon the distance of transmission and transmitting conditions.

Press and release the HL/USER key on the main unit or microphone to toggle the TX power from LOW (1 watt) to HIGH (25 watts). The corresponding LO or HI indicator appears on the LCD.
