2.At the “Enter Channel Number” prompt, type 25 for antenna #1 or 27 for Antenna #2 and press the Enter key. The Analog Input Channel screen for that antenna should then appear on the terminal.

3.Type 6 (for item #6 - Lower Alarm Limit) and press the Enter key.

4.At the “Enter New Data” prompt, type the new value and press the Enter key. The screen should then be updated to show the new value.

7.Type E (to End programming this channel) and press the Enter key. The Setup Selection Menu should then appear on the terminal.

This completes the re-configuration of the Upper and Lower Alarm Limit parameters for the selected antenna channel number. If this parameter needs to be changed for the other antenna, repeat steps 1 through 7 for that antenna.

Antenna SWR Alarm Limit

The upper alarm limit for each antenna’s SWR may be re-configured as follows:

1.With the Setup Selection Menu shown on the terminal, type 6 (for item #6 - Analog Pseudo Channel) and press the Enter key.

2.At the “Enter Channel Number” prompt, type 1 (for antenna #1) and press the Enter key. The Analog Pseudo Channel 1 screen should then appear on the terminal (see Figure 22).

3.Type 7 (for item #7 - Upper Alarm Limit) and press the Enter key.

4.At the “Enter New Data” prompt, type a new SWR upper limit (see Table 8) and press the Enter key. The screen should then be updated to show the new SWR upper limit.

5.Type E (to End programming this channel) and press the Enter key. The Setup Selection Menu should then appear on the terminal.

This completes the re-configuration of the SWR Upper Alarm Limit parameter for the selected antenna channel number. If this parameter needs to be changed for the other antenna, repeat steps 1 through 5 for that antenna.
