All the warning and fault messages are stored in the memory. You can display particularly warning

messages and particularly error messages. They are stored one by one to the memory. You can

see them on the display. If memory is full, every new message will delete oldest one and move rest

of them one position back. It means that every time last 20 messages are visible on the display.

This an example from previous

attempt, when antenna was

disconnected from the PA during

transmitting.

Reflected power was higher than

250W, warning message “Reflected

power too high” appeared.

If you touch the yellow box, warning

details will be visible.

In the case of some hardware failure or if your power amplifier is not working properly, please

contact the manufacturer or your dealer.

Never try to change or move any part inside the amplifier except of tube or fuses.

Substitution of parts may void intrinsic safety!

Fuse Replacement The user is allowed to change mains fuses (6.3 x 32mm), accessible from the rear panel, only. In the case of fuse (fuses) interruption inside the power amplifier, exchange can be carried out only by professionally qualified person! Internal fuses are located mainly on the SWITCH-on board (next to the HV transformer). One special fuse is used in the model OM2000A+. In the case of an accidental discharges in the tube this fuse saves HV supply circuits.
