10. MAINTENANCE
In the event an error occurs, an error message appears at the bottom of LCD display. Make sure of its
nature. Sections 10.1 Error Messages and 10.2 Status Messages will assist you in identifying the cause
of trouble and finding necessary corrective action. If the problem persists, or if you have any question,
contact the factory.

※
1: Even with the run indicator staying off, the white backlight comes on in response to switch operation when backlight is set in the "ON" or "sleep".
※2: In an alarm, the LED blinks at a faster rate (at intervals of 100ms) than in other alarms (at intervals of 250ms). ※3: Outputs can go uncontrolled under certain circumstances if the transmitter fails, however. ※
4: For 5 minutes after occurrence of an alarm condition (or sleep duration of backlight setting), the ORG backlight comes on; after which it will blink on and off.
