Temperature Exceeded
If the Temperature Exceeded indicator message appears, and your projector turns off during use, one of the
following issues is occurring:
• Your projector has overheated internally. The projector can overheat due to a blocked air intake or
exhaustor and ambient temperature over 55°C.
• The temperature outside your projector is too high.
1. Wait 15 minutes for the projector to cool down before attempting to restart.
2. Make sure that nothing is blocking the air intake and exhaust.
3. Disconnect the power cable from the power outlet.
4. Reconnect the power cable.
5. If the previous steps don’t resolve the issue and your projector still doesn’t turn on, disconnect the power
cable, and then contact your authorized SMART reseller.
