button to turn on the receive audio
tone control. LOW will appear on the LCD when the
low tone is activated. This feature will roll-off high
frequency noise (i.e. “white” noise). Under many
operating conditions this will improve the clarity and
understanding of received signals.

SCAN
: Frequency Scan. Scans in increments of 5
kHz. There are two ways to scan using the front panel
controls.
(1) Receive Audio On Scanning: Press the
SCAN
button. Scan rate is one step every 5 seconds. To stop
scanning press the
SCAN
button again, or
momentarily press the PTT button on the microphone
(scanning will stop without transmitting).
(2) Receive Audio Mute Scanning: Carefully rotate the
squelch control a minimum excursion (refer to 14) until
the receive audio is off. The receiver scan rate will now
be five frequencies per second. When a signal is
detected the squelch is automatically disengaged and
the scanning is paused. The squelch circuit will
automatically re-engage and the receiver will continue
to scan the moment the received signal is no longer
detected.
To stop scanning, press the
SCAN
button, or
momentarily press the PTT button on the microphone
(scanning will stop without transmitting).
(3) Memory Scanning: Press the
FUNC
button, and
then press the
M-SCAN
(button 4) The radio will then
scan those frequencies in memory pausing for 3
seconds each time. Scanning will not stop if frequency
is in use. Using the squelch will cause the scanning
only to pause on frequencies breaking the squelch.
SHIFT
: Shift Offset. Used for programming offsets to
operate repeater networks. The OPTIMA can transmit and
receive on different frequencies. The shift default is 000khz
so the offset required will need to be set by the user first.
To program the offset, press the
FUNC
button and hold
down the
SHIFT
button for 3 or more seconds. Three
digits will appear on the LCD screen. This is the offset
frequency in kHz. Rotate the
VFO
control until the desired
offset frequency is displayed. To return to the main display
press the
FUNC
button and hold down the
SHIFT
button for
3 or more seconds, or momentarily press the PTT button on
the microphone (the transmitter will not be engaged).
To activate the programmed offset frequency, press the
FUNC
button, and then press the
SHIFT
button once.
+SHIFT is displayed on the LCD. The radio will now
transmit on the frequency that is XXX kHz greater than the
displayed, or receive, frequency (XXX represents the
programmed offset frequency in kHz).
To transmit on the frequency that is XXX kHz lower than the
displayed, or receive, frequency press
FUNC
, then the
SHIFT
button. Repeat this until -SHIFT is displayed on the
LCD.
To disengage the programmed offset frequency, press
the
FUNC
button and then press the SHIFT button.
Repeat this until the SHIFT indicator is no longer displayed
on the LCD.

: Memory Save. To save in memory a specific
frequency and operating mode, select the desired mode
and rotate the
VFO
control to the desired frequency.
Press the
FUNC
button, and then press the
M.SAVE button. S will appear on the LCD next to the
frequency. While S is displayed, immediately press any
of the memory channel buttons (1 - 5). The mode and
frequency is now saved into memory. If the S indicator
disappears before you press the memory channel button,
the information will not be saved and the process
must be repeated.
