Motorola HT 1000 service manual Transmit Deviation Limit

9.Repeat steps 3 through 8 for the remaining test frequencies. 10.Press F10 to return to the TRANSMIT menu.

NOTE: The step size change for step 5 is approximately 2.5% per softpot value. This adjustment should only be made to the 3kHz deviation. Do not adjust the 80Hz deviation.

Transmit Deviation Limit

1.Press F5 to select the TRANSMIT DEVIATION LIMIT softpot. The screen will indicate the transmit test frequencies to be used.

2.Begin with the lowest test frequency shown on the screen.

3.With the meter selector switch (RTX4005B) set to MIC, inject a 1kHz tone on the AUDIO IN terminal on the test set, 80mVrms as measured on the AC/DC MTR port.

4.Press F6 to key the radio, and use the UP/DOWN arrow keys to adjust the deviation per the values shown in Table 16.

Table 16 Transmit Deviation Limit

BAND	Deviation (KHz)
VHF/UHF/800 MHz	4.30 - 4.60
900 MHz	2.20 - 2.30

5.Press F6 to dekey the radio, and press F8 to program the softpot value. Press ENTER to move to the next softpot value.

6.Repeat steps 3-5 for the remaining frequencies shown on the screen.

7.Press F10 to return to the TRANSMIT menu.

Transmit Deviation Limit Reference

NOTE: This procedure is required for VHF, UHF, and 800 MHz models with 20kHz channel spacing and VHF and UHF models with 12.5kHz channel spacing. This procedure is not required for 900MHz models.

1.Press F6 to select the TRANSMIT DEVIATION LIMIT REFERENCE softpot.

2.With the meter selector switch (RTX4005B) set to MIC, inject a 1kHz tone on the AUDIO IN terminal on the test set, 80mVrms as measured on the AC/DC MTR port.

3.Press F6 to key the radio, and use the UP/DOWN arrow keys to adjust the deviation per Table 17.
