Error type
Expression of Central Icon LED
Note: Pins are monitor microprocessor pins unless otherwise
specified (IC2001).
Lamp failure
Flashes once
(High speed)
H: ON
L: OFF
LAMP_ERR (19pin): Abnormal H.
Confirmed after 8 consecutive detections at 64ms intervals
(detected only when the backlight is on).
NOTE: After 5 detection counts, the lamp cannot be activated
except in the monitoring process.
To confirm the problem, “Lamp Error detection off-mode”
is prepared.
This mode compulsorily starts the set disregarding the
count.
