Initial operational tests on the power supply can be carried out by switching the unit ON and checking the front panel neon
indicator is illuminated. If the neon indicator is not illuminated, check the fuses are intact in the mains plug (where fitted) and the
unit fuseholder on the rear panel.
THIS OPERATION SHOULD ONLY BE CARRIED OUT BY TECHNICALLY COMPETENT

If the front panel neon indicator is illuminated but the console appears not to have any power then it may be necessary to check
the voltages present on the output connector. Refer to the Technical Specification section in this manual for the DC output
voltage levels. If the +16V and –16V DC supplies are not present, check the DC fuses on the front of the power supply. If the
+48V DC supply is not present, check the internal DC fuse located on the power supply circuit board.
