Section 2 – OMNI-VII FRONT
PANEL CONTROLS
Section 2 of the OMNI-VII manual covers
the various controls and connectors on the
front and rear panels, with an explanation of
each control and how it is used for operation
of the radio.
(1) POWER
This switch turns the transceiver power on
and off.
(2) PHONES
This jack uses a ¼” receptacle for plugging
headphones into OMNI-VII. Either stereo or
mono headphones may be used, nominal
impedance 16 ohms, though ‘phones using
an impedance of 8 to 16 ohms load will be
useable with the transceiver. Headphones
above 16 ohms (like 32) can be used
without damage to the transceiver but audio
output to the headphones may be reduced.
When headphones are plugged in, a small
headphone icon will appear near the top left
of the radio screen.
(3) KEY
The front panel provides a ¼” stereo jack for
connection of a key, external keyer, or
paddles. See Figure 2-1 for proper wiring.
OMNI-VII on initial power-up has the internal
keyer disabled. To use the internal keyer in
a CW mode, press the SP button (‘SPeed’)
and then rotate the MULTI knob for an
appropriate CW speed (Note: In SSB
modes, SP is used for speech processing
and displays a different value).
