SET-UP PROCEDURE

Set-up Procedure
1. Remove the cover.
2. Connect input signal to the “Input” of the RF switch compartment.
3. Connect the “Output to Secondary Amp” of the RF switch compartment to the “Input” of the amplifier compartment.
4. Connect the “Output” of the amplifier compartment to the “Input from Secondary Amp” of the RF switch compartment.
5. Connect the “Output to Primary Amp” of the RF switch compartment to the “Input” of an external amplifier.
6. Connect the “Output” of the external amplifier to the “Input from Primary Amp” of the RF switch compartment.
7. Connect signal strength meter to the “Output” of the RF switch compartment.
8. Adjust the external amplifier to get the desired level.
9. Connect 24 VDC or 24 VAC to the appropriate input of the power supply compartment.
10. Push the “Set Ref. Levels” switch.
11. Connect the “+” and “-” contact of the remote switch with a jumper to force the microcontroller switch to the secondary
amplifier.
12. Adjust the gain and slope control in the amplifier compartment to get desired signal level.
13. Remove the jumper from the remote switch.
14. Remove the signal strength meter from the “Output” of the RF switch compartment.
15. Connect the “Output” of the RF switch compartment to the desired output cable.
16. Use a voltmeter to measure the DC voltage on the “Secondary Amp DC Level” test point. Adjust the variable attenuator
on the secondary amp level detector to get the voltage to a nominal 2.5V if possible. (For lower RF levels, the detected
DC voltage may not reach 2.5 VDC. This is normal).
17. Use the voltmeter to measure the DC voltage on the “Primary Amp DC Level” test point. Adjust the variable attenuator
on the primary amp level detector to get the voltage close to the voltage on the “Secondary Amp DC Level” test point.
18. Put the cover back on.
19. Press “Controller Reset”.
20. Press “Set Ref Levels”.
