Service Information

NOTE

The LEDs only indicate the presence of a DC voltage, not the DC voltage level. Use
the indicated wire locations for voltage measurements, TP1 is your common. Refer
to

d.

If there is no DC power, suspect the power supply module. The actual power
supply terminal connection should also be confirmed with a DVM by removing
the bottom cover and using the power supply label to identify the terminal
voltage values.

e.

If all of the DC Input LEDs are On and the fan is not working, replace fan.

f.

Using a DVM confirm that the RF Switch power regulator output (> 21 Vdc) is
present on the Switch Driver board, at the side of the SMT Cap (C90) as shown
in

NOTE

The +9 and -10 Vdc indicators are not used in this instrument (Off is normal).
