3 Set the VOL control to a comfortable listening

4 If the squelch will be used, select the type of

squelch you want, and adjust as explained earlier
{page 16}.

To transmit, proceed to the subsequent steps.

5 Listen. Make sure that your transmission won’t

interfere with others.

6 Press and hold [PTT] on the microphone.

7 Speak into the microphone.

• Speak in a normal tone of voice. The RF meter

should indicate from 7 to 9 on voice peaks
when using High power. The meter will read

lower when using the Low power. Speaking too
close to the microphone, or too loudly may
increase distortion and reduce intelligibility.

8 As you transmit, verify that the RF Meter is reading

upscale confirming transmit output power. The
microphone gain is controlled automatically;

however, if you prefer to set the gain manually,
refer to the following.

• Microphone gain adjustment is via Menu B,

Nos. 61 and 62 {page 14). No. 61 toggles a
circuit ON or OFF to maintain a constant level
regardless of variations in your speech level.
Turning No. 61 OFF sets the microphone gain
to a fixed value. This fixed value is selected
from No. 62 which allows you to control the gain
over a 12 dB range with 5 discrete selections.

Each selection is 3 dB higher than the previous

with the default being the mid-range selection of

OdB.

CW PITCH CHANGE

The CW receive pitch can be selected from within the

range of 400 Hz to 1000 Hz in 50 Hz steps by

changing Menu A, No. 02 {page 13}. The default is
800 Hz.

You may prefer selecting a higher pitch for easier
copy through interference from other stations. When
copying a strong signal on a clear frequency, you may
find it more pleasant to select a lower pitch. Changing
this setting does not affect the transmit sidetone.

CW KEYING DELAY

Menu A, No. 01 {page 13} allows keying delay time
selection. This is the delay before the transceiver
returns to the receive mode after the key is released.
Various delay values are available . The default is
600 ms.
