- Fl display description of indications key operation 32
- Main unit s operations when a dc voltage or temp error is detected are described in this section because no key input is accepted after a dc or voltage error is generated follow the instructions described in 3 how to cancel the status after detection of a dc error 32
- Note if the unit returns to a normal status within 3 sec after a dc error was detected it can be turned back on again after the shutdown caused by the detection if dc is successively detected for 3 sec or more the unit cannot be turned on after the shutdown caused by such detection for turning the unit on follow the instructions described in 3 how to cancel the status after detection of a dc error 32
- Note the unit cannot be turned on after the shutdown caused by such detection for turning the unit on follow the instructions described in 3 how to cancel the status after detection of a dc error 32
