7.1 Troubleshooting
PROBLEM
During a power failure,
extensions assigned for
power failure operation do
not operate.
Originating an outside call,
Call Transfer, or
Conference cannot be per-
formed.
7.1.4 Using Reset Button
PROBABLE CAUSE
• A DPT or APT is con-
nected to the extension
port.
• The dialing mode (tone or
pulse) is improper.
The corresponding CO but-
ton does not exist on the
proprietary telephone.
If the system does not operate properly, use the Reset Button.
Before using the Reset Button, try the system feature again to con-
firm whether there definitely is a problem or not.
Notes:
(a) When the System Clear Switch is set to "NORMAL," pressing
the Reset Button causes the following:
1. Camp-on is cleared.
2. Calls on Hold are terminated.
3. Calls on Exclusive Hold are terminated.
4. Calls in progress are terminated.
5. Call Park is cleared.
Other data stored in memory except the above is not cleared.
(b) When the System Clear Switch is set to the "CLEAR" posi-
tion, you must press the Reset Button with caution. All data
stored in memory will be cleared by the following operation:
pressing the Reset Button and setting the System Clear Switch
to the " NORMAL" position while the Power Indicator is
flashing.
Operation
(A) If the system does not operate properly,
1. Make sure that the System Clear Switch is set to the

2. Press the Reset Button with a pointed tool.
POSSIBLE SOLUTION
• Disconnect the DPT or APT and
