The temperature is abnormally high.
• The temperature protector has been activated. If the room tem-

perature is high, move the projector to a cool place. If the
projector’s internal temperature is high, check the cooling fan’s
ventilation slots and clean them if they are clogged.

• When the temperature protector is activated, the power turns

off and in some cases will not turn back on immediately. In this
case wait about 90 seconds, then try again.

The fan has stopped.
Unplug the power cable and contact a store that sells the U4-237
for repairs.

Should an indicator be in a condition other than normal or flash at a rate other than the aforementioned, disconnect the power
cable and contact your store of purchase.

Thermal Protector

When the temperature inside the projector becomes abnormally high, the STATUS indicator blinks red (0.5 seconds on/0.5
seconds off), the STANDBY indicator is a steady red, and at the same time the temperature protector operates and switches off
the power of the projector.
Should this happen, please take the following actions.

1. Switch off the power and disconnect the power plug from the wall outlet.

2. Check the following matters and take the required measures.

When the projector is being used in a location that has a high ambient temperature, set it up again in a cool location. Check the
outflow and intake holes and clean them if they are obstructed.

3. Wait about 60 minutes until the temperature of the projector drops.

If after having performed the above matters, the problem still has not been solved, please contact your store of purchase.

STATUS

The lamp will not light.
Wait at least 90 seconds, then turn the power back on. If the
problem persists, unplug the power cord and contact a store
that sells the U4-237 for repairs.
