WARNING

Disconnect AC power from the unit before removing the cover. Even when the front panel power switch is in the OFF position, live line voltages are exposed when the cover is removed. Repairs and adjustments must be made by experienced service technicians only.

WARNING

Use a non-conducting, straight-blade screwdriver to adjust the trim pots.

CAUTION

Follow established antistatic procedures. There are static-sensitive parts on the printed circuit boards.

You will need to remove the power supply’s cover to access the programming and readback calibration potentiometers which are located on the A2 PCB. See Figure 5.1 to locate the potentiometers.
