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.
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.

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.
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.
