M E N U
to
turn off the sidetone and return to the S T L display.
Note: S T L is used to set the sidetone volume level in relation to
normal received audio. However, the AF GAIN control sets the
overall headphone or speaker volume.
Select the sidetone pitch menu entry (STP) using by tapping
W P M +

M E N U
to end
parameter edit and return to S T P .
Tap
M E N U

E 4 2 because of the missing VFO signal).
Voltmeter
On power-up, the LCD shows the operating frequency, with
100-Hz resolution. Holding
D I S P L A Y

again. You should see E 4 2 , as explained previously.
Keyer
Note: If you don’t have a keyer paddle, you can still test the DOT
and DASH lines by using test clips to touch them to ground.
Plug a keyer paddle into the key jack (J3). The plug must be
stereo (2 circuit). A stereo plug is supplied with the kit.
Tap
M E N U
and locate the I N P menu entry (CW input device
selection). Hold
E D I T

P D n or P D r (paddle normal, or paddle reverse). Then tap
M E N U
twice to return to the VFO display.
Select the keyer speed using
W P M +
and
W P M -
. If you tap
these switches quickly, the speed will jump 2 WPM at a time.
While listening with headphones, test the keyer paddle to
verify that both dot and dash are working.
If you use a dual-lever keyer paddle, you may wish to use the
menu’s I A B entry to select iambic mode A or B (page 55).
