[3] The unit's operation when a error is detected
[Purpose]
• The unit's operation when a DC/OVER/TEMP error is detected is described here.
• How to cancel the status after detection of a DC error is described here, because no key input will be
accepted after a DC error detection.

*1 The time required for the unit to be shut off after an error is detected depends on the circuit configuration.
(However, 3 seconds after DC is internally detected, the unit will shut itself off.)
*2 If the unit is automatically shut off after a DC error is detected, no key input will be accepted afterward.
(The power will not be turned ON.)
To turn it on again, see "3.4 How to cancel the status after detection of a DC error" below.
A key input will not be inhibited after an OVERLOAD/TEMP error is detected. (The unit can be turned ON.)
