bottom of the LCD). You may scroll the display through 17 rows of functions available
for use via the [

DSP
Button
Pressing this button momentarily provides instant access to Multi Function Row “p”
(
MFp
), which contains the command key for the optional receiver’s Digital Signal Pro-
cessing system. The available functions will appear as the functions displayed above the
[
A
], [
B
], and [
C
] keys, as described previously. Pressing this key once more will return
operation to the last-used Multi-Function Row (the one in use before the DSP row was
engaged).
Press and hold in this switch for one second to activate Menu Item No-048, for adjust-
ment of the DSP Microphone Equalizer (see page 51 for details).
POWER
Switch
Press and hold in the
POWER
switch for one second to turn to the transceiver on or off.
While the transceiver is turned on, pressing this switch momentarily will engage the
“Fast Tuning” mode, to allow more rapid frequency navigation (a small “running man”
icon will be observed in the bottom right-hand corner of the LCD).
TX/BUSY
Indicator
This indicator glows green when the squelch opens, and turns red during transmit. Dur-
ing CW operation, this indicator will glow blue when an incoming signal is tuned to the
center of the passband (with IF Shift off). And during FM reception, this indicator will
glow blue when a signal is received with a CTCSS/DCS tone matching that to which
your transceiver is set.
