FT-920 Operating Manual
26
(50) L
OCK
Switch (B)
This switch locks the settings of the VFO-B knob and/
or the front panel keys.
Pressing this switch momentarily locks the settings
of the VFO-B Tuning Dial. Pressing and holding in
this switch for ½ second causes all the keys on the
front panel of the transceiver (except for the [L
OCK
]
switches!) to be locked. When the L
OCK
function is
engaged, the “L
OCK
” indicator will be shown on the
display panel.
(51) M
ENU
Switch
Pressing this switch momentarily activates the “Menu”
mode, which allows customization of many aspects
of transceiver configuration.
(52) RX C
LAR
Switch
Pressing this switch activates the RX Clarifier (Off-
set Tuning from VFO-A frequency) feature. When this
feature is activated, the VFO-B Tuning Knob is used
for Clarifier tuning up to an offset of ±9.99 kHz.
(53) TX C
LAR
Switch
Pressing this switch activates the TX Clarifier fea-
ture, allowing the transmit frequency to be offset from
the VFO-A frequency up to ±9.99 kHz. The TX Clari-
fier may be used in conjunction with the RX Clarifier,
or the chosen offset may be applied either to the RX
or TX frequency singly.
(54) C
LEAR
C
LAR
Switch
Pressing this switch clears any offset that has been
established for the Clarifier, returning it to a “Zero
Offset” condition. Pressing this switch only cancels
the offset; it does not turn the Clarifier itself off.
(55) S
POT
Switch
In the CW mode, this switch activates a spotting tone,
used for precise zeroing in onto an incoming (RX)
signal. By matching the pitch of the incoming signal
exactly to the pitch of the Spot tone, your transmitter’s
signal will be precisely aligned to a “Zero Beat” posi-
tion relative to the other station’s signal.
