10 Maintaining an I-Series Intercom Panel
This chapter provides maintenance information: troubleshooting tips, block diagrams,
component layout drawings, bills of materials, and schematics.
CAUTION: These servicing instructions are for use by qualified personnel only. To reduce
the risk of electrical shock, do not perform any servicing other than that contained in the
operating instructions unless you are qualified to do so.
10.1 General Troubleshooting
Every I-Series panel’s microprocessor has a reset button located, as shown in Figure 1, in
an unmarked hole located next to the program volume knob (labeled “VOL/PROG”). If a
panel acts erratically, try resetting it. Often this will clear the problem.
To reset a panel, insert a small screwdriver or a piece of wire (such as a bent paper clip)
into the hole and push the reset button. Another way to reset the panel is to disconnect
and re-connect the AC power cord.
