5. 1. 2. Light source/temperature indicators
• If a problem occurs inside the projector, the light source indicator <LIGHT> or the temperature indicator <TEMP> will inform
you by lighting or blinking.
Light source indicator <LIGHT>
Indicator status
Lighting in red
Blinking in red
(2 times)
Blinking in red
(3 times)
Status
Some of the elements of the light
source are defective and the light
output has decreased.
The light source does not light up, or the light source turns off while the
projector is in use.
Cause
―
Solution
f
Turn the <MAIN POWER> switch to <OFF> , and turn on the power again.
Note
f
The light source indicator <LIGHT> lights in green while the projector is in projection mode if there is no notification by lighting or blinking in
red.
Temperature indicator <TEMP>
Indicator status

Blinking in red
(2 times)
Blinking in red
(3 times)
Status
Warm-up status

stopped.
Cause
f
Did you turn on the power
when the temperature
was low (around 0 °C
(32 °F))?
f
Is the air intake/exhaust port blocked?
f
Is the room temperature high?
―
Solution
f
Wait at least five minutes
in the current status.
f
Use the projector
in an appropriate
operating environment
temperature
*1
.
f
Remove any objects that are blocking the air intake/
exhaust port.
f
Use the projector in an appropriate operating
environment temperature

f
Do not use the projector at an altitude of 4 200 m
(13 780') or higher above sea level
*2
.
f
Repair
*1 The operating environment temperature of the projector differs depending on the altitude or the setting of the [PROJECTOR SETUP] menu → [ECO
MANAGEMENT] → [OPERATING MODE]. Refer to “Operating environment temperature” for details.
*2 When the [PROJECTOR SETUP] menu → [ECO MANAGEMENT] → [OPERATING MODE] is set to [ECO] or [SILENT], the projector cannot be
used at an altitude of 2 700 m (8 858') or higher above sea level.

2) Set the IP address of computer to approximate value of projector IP address.
3) When connecting using DIGITAL LINK compatible device.
The [DIGITAL LINK MODE] of sub menu [NETWORK], please set to [AUTO] or [ETHERNET].
[Note]
• If you have changed the each menu settings, please return settings of the original (customers) after work.
2. Connect the projector and the PC by using a communication cable.
5. 3. 3. Acquisition of log data
1. Switch the projector to "Normal-Standby" mode (STANDBY/ON indicator is lighting in red).
2. Activate a [DataLogBackup.exe] service software.
