Time (sec.) Description of Indications
[Purpose]
• The unit’s operation when a DC/OVER/TEMP/POWER error is detected is described here.
• How to cancel the status after detection of the DC and POWER errors are described here, because no key input will be
accepted after the DC or POWER error detection.
The following processes will take place:
[1] Immediately after a DC error is detected, muting is turned ON and speaker relay is turned OFF.
[2] The DC error count is increased by 1.
[3] The DC circuit is monitored for 3 sec.
[3-1] If the circuit is normalized within 3 sec., the unit will return to a normal mode.
[3-2] If the circuit cannot be normalized within 3 sec., the unit will shut itself OFF.
[3-3] If a user turns the unit OFF within 3 sec. after the detection, it will be turned OFF.
[4] If the unit shuts itself OFF as mentioned in [3-2], you cannot turn it ON unless you perform the procedures described in
“How to cancel the status after detection of a DC or POWER PROTECTION error.”

(OVERLOAD detection)
Time (sec.) Description of Indications
The following processes will take place:
[1] Immediately after an OVERLOAD (overcurrent) error is detected, muting is turned ON and speaker relay is turned OFF,
then the unit is turned OFF.
The processes of muting ON and speaker-relay OFF must be completed before the unit is turned OFF.
[2] The OVERLOAD (overcurrent) error count is increased by 1.
Key operations will not be prohibited even after detection of such an error. (The unit can be turned ON.)
