9. FAILURE INDICATION
The FS-7000CP, FS-7000JP, FS-7000RF, FS-7000RM, FS-7006PA, and FS-7012PA are equipped with
failure indicators that show the status of any problems that may occur. When such an indicator lights or
flashes, it means that a problem may have occurred in the equipment or in the wiring.
If the power indicator is not illuminated, the equipment could be malfunctioning. In such cases, check to see if
power is being supplied correctly, or if a fuse has blown. A blown fuse often means that the problem may have
occurred within the wiring as well as in the equipment itself.
In such cases, replace the fuse(s) and check the correctness of the wiring before turning the power on again.
If an indicator lights continuously or flashes, the following possible causes may be considered:
Symptom Possible Cause Check/Remedy

7000RM units.
• Confirm that the FS-7000RM's address is
set correctly.
• Confirm that there is no fault with the
wiring leading to the FS-7000RM.
If all of the above are found to be in
correct working order, then it is likely that

• Confirm that there is no fault with the
wiring leading to the FS-7000RF.
If all of the above are found to be in

If the indicator light does not go out, or if it
goes out but then lights again within a
short period of time, consider whether the
following may be the problem:
