longer detected. To stop scanning, press the SCAN
button, or momentarily press the PTT button on the
microphone (scanning will stop without transmitting).
SHIFT
Used for programming offsets to operate repeater net-
works. The DELTAFORCE can transmit and receive
on different frequencies.
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. This is the offset
frequency in kHz. Rotate the FREQUENCY 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 momen-
tarily 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
DELTAFORCE will now transmit on the frequency that
is XXX kHz greater than the displayed, or receive, fre-
quency (XXX represents the programmed offset fre-
quency 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 dis-
played 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 dis-
played on the LCD.
MEMORY CHANNEL 3
After programming this button is memory channel 3.
See M.LOAD \ M.SAVE control for programming in-
structions.
(15)FUNCTION
This control is used to operate the functions that are
printed below the control buttons. Press and release,
FUNC will be displayed on the LCD indicating that the
function command is activated. After you have pressed
one of the buttons the FUNC will disappear from the
screen.
(16)LAST CHANNEL RECALL
Press the LCR button to return to the last frequency
that was transmitted on for more than 3 seconds.
REPEATER
Repeater access tone on and off control. Most repeat-
ers require an 88.5 Hz tone burst to access. To acti-
vate the 88.5 Hz tone burst, press the FUNC control
and then press the RPT button. RPT will appear on the
LCD indicating that the tone burst will now automati-
cally be transmitted whenever the PTT is pressed. To
deactivate, repeat the same process.
MEMORY CHANNEL 4
After programming, this button is memory channel 4.
See M.LOAD \ M.SAVE control for programming in-
structions.
(17)STEP
The STEP button selects frequency resolution in ei-
ther 1 kHz, 10 kHz or 100 kHz steps. Press the STEP
button, one of the digits will flash on and off. Press the
STEP button again to change stepping resolution.
To tune frequencies in either 10 kHz or 100 kHz incre-
ments, press the STEP button until the desired digit is
flashing. Rotate the FREQUENCY control in either di-
rection. The entire frequency range of the Magnum
DELTAFORCE can be stepped through in 10 or 100
kHz increments.
To tune in 1 kHz increments, press the STEP button
until the 1 kHz digit flashes on and off. Rotate the FRE-
QUENCY control. NOTE: When stepping in 1 kHz in-
crements, you are limited to tuning within a 10 kHz
frequency range.
NOISE BLANKER and
AUTOMATIC NOISE LIMITER
Noise blanker on and off control. This circuit eliminates
pulse type interference usually associated with auto-
motive ignition systems. To activate the noise blanker,
press the FUNC control and then press the NB button.
NB will appear on the LCD indicating the noise blanker
is turned on. To turn off the noise blanker, repeat the
same process.
MEMORY CHANNEL 1
After programming, this button is memory channel 1.
See M.LOAD \ M.SAVE control for programming in-
structions.
(18)CALL
The USA national call frequency for SSB is 28.400 MHz.
The radio’s operating frequency is automatically reset
to this frequency when the CALL button is pressed.
MEMORY CHANNEL 2
After programming this button is memory channel 2.
See M.LOAD \ M.SAVE control for programming in-
structions.
(19)MODE
Each time the button is pressed the operating mode is
changed. The operating mode is indicated on the liq-
uid crystal display: AM, FM, USB, or LSB.
