Screen no display or
- -
display insufficiency
NOTE:
1. When the unit has error, the buzzer of the operation panel will make an alarm sound, and there will
show "Alarm" on the screen panel.
2. "ERROR CODE" will show on temperature display location by alternately.
3. Part of the error alarm can be automatically restored (resumed). That is the appeared alarm can be
eliminated by electronically controlled self-test.
4. Some of the error alarm is caused by large fluctuation of the external power, by this, just power off and
restart the unit to clear the error.
5. When the machine has error alarm and restart still can not eliminated error, please contact the after
service as soon as possible for solution.
