requirements of the user.

See SETUP 5 before carrying out this procedure.

1)

Ensure that the R.F. probe fitted to the directional coupler is
correctly orientated. Increase the output power for an external
reading of 3000 W.

2)

Adjust trimmer R66 on the protection card to obtain the same reading
on the VJ3000 meter (9 Fig.3) as on the external wattmeter.

3)

Reduce power to 1500W (equivalent to a 3dB drop).

4)

Connect an Ohmeter between pin 9 of the Telemetry connector
(SETUP 9) and ground.

5)

Adjust trimmer R158 to cause the Ohmeter to read open circuit. This
will establish the Power Good threshold.
