MAINTENANCE
INTRODUCTION
This chapter provides station microprocessor resetting instructions, maintenance
menu use, troubleshooting guidelines, schematics, assembly drawings, and
component lists.
STATION RESET
The station’s microprocessor has a reset button located in an unmarked hole just
below the program volume knob on the right side of the unit’s front panel. If the
station is acting erratically, try resetting it by performing one of the following:
• Insert a small screwdriver or a stiff piece of wire (such as a bent paper clip) into
the hole and pushing the reset button.
• Unplug the station from AC power and reconnect.
TROUBLESHOOTING
When experiencing the symptoms listed below, attempt the following solutions
in the order outlined. The solutions are listed in order of difficulty with the first
being the most simple and easy.
• The station’s display and all front-panel indicators fail to light.
1. Check mains AC power into the station.
2. Ensure the external power supply is properly connected to the station.
3. Replace the station.
• The display shows unexpected characters.
1. Power the station off and turn it back on.
2. Reset the station’s matrix card in the matrix frame.
3. Replace the station.
