Tests & Adjustments
Keypad Button Functions
Below is a description of the non-numeric
keys used during the keypad calibration
procedure:
Step 1. Connect the test cable RF to a
servicing analyzer, using a coaxial cable.
Enter Manual Test Mode.
Depress the # button. The display should
show the ’ prompt.
Step 2. Enter 11434# via the keypad to
program the synthesizer for channel 434.
Step 3. Enter 05# to key the transmitter.
TX Output Power Adjustment(Center of
Band)
Step 4. Enter 73#. The portable display will
show Step number “00” on the left and the
corresponding hex value for the TX output
power on the right.
Step 5. Using the * button to advance
through the power steps. Adjust
each of the power steps listed in
Table 6: “Output Power Levels” for the val-
ues shown as indicated on the servicing ana-
lyzer. Make adjustments as described in Step
6 and Step 7.
Step 6. Enter a 2-digit hexadecimal number
via the keypad. This immediately updates the
hex power level value, and the output
power should change as indicated on the
analyzer. If the new entry does not produce
the desired analyzer reading (i.e. too high or
too low),
a) depress the CLR button and enter another
2-digit number, or
b) use the VOL button to incrementally
increase the hex value to obtain the desired
reading on the analyzer. (The volume control
may not be used to decrease the hex value.)
