Figure 55. Model 640 Database POCSAG Subscriber Record
Note: The example shows a POCSAG pager, but another type of digital pager record will
also work. Program a record that corresponds to the equipment you intend to use.
The Model 640 database programming for the radio station adjustments is complete. Continue
with the alignment procedures below.
VOICE Audio Adjustment
Follow the steps below to perform the VOICE audio adjustment:
q 1. Call the first 2-tone test pager defined in Figure 54. The Model 640 responds with 3
short beeps to indicate the start of voice message recording.
q 2. Hold down a key on the touch-tone phone, so that a long tone is recorded.
q 3. Hang up or press pound (#) to terminate recording.

4. Use the radio service monitor to measure the RF deviation of the transmission. While
the long DTMF tone is playing, adjust the VOICE potentiometer on the rear panel of
the paging terminal for about 3.0 - 4.0 kHz deviation. Figure 56 shows the location of
the radio station pots.
