Tests & Adjustments

reading is 9.0 rad + 10%, proceed to Step 30.

If it is not, enter 72#, use the * button to tog-

gle down to Step 07 (left side of display),

and use the volume control or enter numbers

via the keypad (as explained in Step 6) to

adjust for a deviation of9.0 rad + 10%.

After adjustment, exit the 72# command by

repeatedly depressing the * button until the

display shows the ’ prompt.

Step 19. Enter 34# to turn off the DTMF

tone.

SAT Deviation Adjust

Step 20. Enter 251# to enable a 6000 Hz

SAT tone.

Step 21. Read the average deviation on the

communications analyzer. If the reading is

1.4 kHz + 10% (corresponds to 2.0 kHz

peak), proceed to Step 33. If it is not, enter

72#, use the * button to toggle down to Step

09 (left side of display), and use the

volume control or enter numbers

via the keypad (as explained in Step 6) to

After adjustment, exit the 72# command by

repeatedly depressing the * button until the

display shows the ’ prompt.

Step 22. Enter 26# to turn off the 6000 Hz

SAT tone.

Data Deviation Adjust

Step 23. Enter 14# to turn on the 10 kHz

signaling tone.

Step 24. Read the average deviation on the

communications analyzer. If the reading is

5.7 kHz + 10% (corresponds to 8.0 kHz

peak), proceed to Step 36.

If it is not, enter 72#, use the * button to tog-

gle down to Step 08 (left side of display),

and use the volume control or enter numbers

via the keypad (as explained in Step 6) to

display shows the ’ prompt.

Step 25. Enter 15# to turn off the 10 kHz

signaling tone.RX Discriminator Adjust

RX Discriminator Adjust

Step 26. Inject a -50 dBm, 883.020 MHz

(channel 434) signal FM modulated with a 1

kHz tone at + 2.9 kHz deviation into the

antenna port, using an SLN8576A antenna

test adaptor.

Step 27. Enter the following commands:

08# to unmute the RX audio 474# to set the

receive audio volume to level 4356# to select

the external handset audio path

Step 28. Enter 72#, use the * button to toggle

down to step 0A (left side of display), and

use the volume control or enter numbers via

the keypad (as explained in Step 6) to obtain

100 mV rms +15% at pin 7 of J3 (RX audio

out). After adjustment, exit the 72#

command by repeatedly depressing the *

button until the display shows the ’ prompt.

Step 29. Exit Manual Test Mode by

depressing the PWR button. This

completes the keypad adjustment

procedure.
