MOX Switch
Pressing this button engages the PTT (Push to Talk)
circuit, to activate the transmitter. It must be in the
undepressed position for reception. This switch rep-
licates the action of the Push to Talk (PTT) switch on
the microphone. When engaging the [ MOX ] switch,
or otherwise causing a transmission to be started, be
certain you have either an antenna or 50-Ohm dummy
load connected to the selected Antenna jack.
VOX Switch
VOX Operation: This button enables automatic voice-
actuated transmitter switching in the SSB, AM, and
FM modes. While activated, the LED inside this but-
ton glows red. The controls affecting VOX operation
are the front panel's [ VOX ] and [ DELAY ] knobs (see
section below. By proper adjustment of these con-
trols, hands-free voice-actuated operation is possible.
DIM Switch
Press this button to lower the illumination intensity
of the analog meters, the frequency display, and the

PHONES Jack
A 1/4-inch, 3-contact jack accepts either monaural or
stereo headphones with 2- or 3-contact plugs. When
a plug is inserted, the loudspeaker is disabled. With
stereo headphones such as the optional YH-77STA,
you can monitor both Main (VFO-A) and Sub (VFO-
B) receiver channels at the same time during Dual
Receive operation.

When wearing headphones, we recommend that you
turn the AF Gain levels down to their lowest settings
before turning power on, to minimize the impact on
your hearing caused by audio "pops" during switch-
on.

POWER Switch

Press and hold in this switch for two seconds to turn
the transceiver on, after first setting the rear panel
Power switch to the " I " position. Press and hold in
this switch for two seconds, similarly, to turn the trans-
ceiver off. If the rear panel's Power switch is set to
the " O " position, the front panel [ POWER ] switch

This is the actual power On/Off switch for turning on
the transceiver. When the rear panel's Power switch
is set to the " I " position, power is supplied to the
OCXO to stabilize the reference oscillator, and the
remainder of the transceiver is set in a "stand-by"
mode, awaiting the command for the transceiver to
switch on via the front panel [ POWER ] switch. For
further information on the rear panel Power switch,
please see the discussion on page 36.
