Internal System Alignment Routine
This uses a programmed routine in the transceiver
which simplifies many previously complex discrete
component settings and adjustments with digital-
ly-controlled settings via front panel buttons and
LCD indications.
1. To begin, set the transceiver to the VFO mode
on the "A-Band" in the "Mono" band mode.
2. P r o g r a m a p a s s w o r d f o r t h e A l i g n m e n t
(AH044M) according to the following proce-
dure:
1) Press and hold the [ DISP ( SET )] key for one
second to enter the Set mode.
2) Rotate the DIAL knob to select Set Mode Item
1: DISPLAY.
3) Press the [ ENT ] key briefly to enable adjust-
ment of this Set Mode Item.
4) Rotate the DIAL knob to select Set Mode Item
9: OPENING MESSAGE.
5) Press the [ ENT ] key briefly to enable adjust-
ment of this Set Mode Item.
6) Rotate the DIAL knob to select Set Mode Item
MESSAGE.
7) Press the [ ENT ] key briefly to enable adjust-
ment of this Set Mode Item.
8) Program the password "AH044M" using
the DIAL knob (select the character ), and
[ BAND ] / [ Dx ] key (move the cursor).
9) When you have completed the password,
press the [ DISP ] key briefly, then press the
PTT switch to exit to normal operation.
Note: Remember to delete the password "AH044M"
from the Set Mode Item 9: OPENING MESSAGE when
the alignment adjustments are finished by pressing and
holding in the [ GM ] key for two seconds (as in step 8
above).
3. Press the [ PWR ] switch for two seconds to turn
the transceiver "off".
4. Press and hold in the [ GM ] key while powering
the transceiver "on" again. The transceiver will
enter the adjustment mode, and the display
will show the first alignment setting. Thereaf-
ter, the frequencies used during alignment will
automatically be set without action by the tech-
nician.
In the alignment process, each adjustment is se-
lected by rotating the DIAL knob. The alignment is
performed by: pressing the [ V/M ] key (the "E" icon
will appear on the display); injecting a signal of the
required frequency and level; making the adjust-
ment; and then pressing the [ V/M ] key again (the
"E" icon will disappear from the display), to store
the adjustment.
To exit the alignment routine, press the [ GM ] key.
After performing the system alignment in its en-
tirety, individual settings can be returned to and
adjusted individually, should the need arise.
As each transceiver is individually optimized at
the factory, the precise settings for the transceiver
on your bench may be slightly different.
PLL Reference Frequency Adjustment (PLL REF)
Connect the test equipment as shown in Figure 1:
TX Alignment Setup.
Rotate the DIAL knob to select the Alignment
Menu "PLL REF".
Press the [ V/M ] button (the "E" icon will appear
on the display).
Press the PTT switch to transmit and rotate the
DIAL knob so that the frequency counter setting
is 440.000 MHz (±100 Hz).
Release the PTT switch, then press the [ V/M ]
button (the "E " icon will disappear from the
display).
