Switch is set to an appropriate frequency).
Toggling the [AUDIO] switch selects either the internal variable
alignment tone or
transmitted voice from the headset or
speaker.
AUDIO volume is a knob that adjusts the volume heard in
either the hidden front panel speaker (located behind the
circular front panel graphic),
or the headset’s earpiece. The
speaker is only ac
tive when there is no headset plugged into
the ’Headset’ jack.
The setting of the [MASTER/SLAVE] switch affects the
transmitted frequency of the 2240. The transmitted frequency
will be 20 MHz above the set frequency (set by the
thumbwheel sw
itches) when the [MASTER/SLAVE] switch is
set to ’MASTER’; 19 MHz below the set frequency when the
[MASTER/SLAVE] switch is set to ’SLAVE’. This 39 MHz offset
makes possible full-
duplex voice transmission and
measurement between the two 2240s.
