MAINTENANCE
INTRODUCTION
This chapter provides panel microprocessor resetting instructions,
maintenance menu use, troubleshooting guidelines, schematics,
assembly drawings, and component lists.
PANEL RESET
The panel’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 panel 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 panel 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 panel’s display and all front-panel indicators fail to light.
1. Check mains AC power into the panel.
2. Ensure the external power supply is properly connected to the
panel.
3. Replace the panel.
• The display shows unexpected characters.
1. Power the panel off and turn it back on.
2. Reset the panel’s matrix card in the matrix frame.
3. Replace the panel.
• The LED indicator above a selector does not light when the
selector is pressed.
1. Ensure the selector has a label assigned to it (the LED indicator will
not light without an assigned label).
2. Reset the panel.
3. Replace the panel.
• Keypad button functions do not operate, or the panel beeps
when a button is pressed (affected buttons could include
“Assign,” “Panel,” “Dial,” “Menu,” and “Swap”).
