Figure 8: Key Functions for Paging Encoder Setup
Keypad “1” = Test/Adjust Equalization Curve #1
Pressing the “1” key on the paging keypad will send a function sequence out on the
channel (F1-F8) that was selected when the setup mode was entered. This will key up the
transmitter while a test tone at 0 dBm sweeps from 300 to 3000 Hertz repeatedly. Using a
service monitor measuring deviation on the transmit frequency, the frequency response
may be equalized so that paging tones are transmitted with equal levels across the
frequency spectrum. This test provides 30 points across the spectrum that can be adjusted
+/-10 dB each. To make adjustments, use the “*” and “#” keys (also marked as down and
up) to adjust the level in dB, and the “7” and “9” keys to select which of the 30 frequency
bands to adjust. Holding any of these keys will “freeze” the sweep at the frequency shown
on the LCD display so the measurement can be made on the service monitor. For each of
the 30 points, adjust the amplitude up or down until the deviation is correct. When all
frequency bands have been adjusted, save the equalization by pressing the “1” key again,
or cancel the adjustments by pressing the “CLEAR” key or Setup mode Key #9.
Keypad “2” = Test/Adjust Equalization Curve #2
Everything works similarly to keypad “1” except that it applies to the second equalization
curve data set. To save any changes made, be sure to press the “2” key again prior to
pressing the “CLEAR” key or the Setup mode #9 key to exit the test. Cancel the changes
made by just pressing “CLEAR” or Setup mode #9 without pressing “2” first.
To end the setup mode, press the “CLEAR” key or Setup mode Key #9. The Setup mode
will also self-cancel after two minutes of keyboard inactivity. The remainder of the
features and options are set in the PC off-line configuration software. On-line help is
available within this software.
