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

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.)

Step 7. With all necessary adjustments made

and power Step “0B” showing in the display,

depress * to enter all updated data and exit

the 73# command.
