Troubleshooting Cause The air filter is dirty. The lamp has ruptured (or there is a lamp malfunction). The operating environment is inappropriate. Countermeasure Check whether the air filter is clogged with dust. If the air filter is clogged, clean or replace the air filter (P207, P208). If the lamp has ruptured, follow the instructions in "Note the following precautions when replacing lamps that stop working. Failure to do so could result in personal injury." (P19). Check whether the operating temperature is between 0°C (32°F) and 40°C (104°F) (P24). Projector settings must be adjusted when using the projector at altitudes of 2,300 m (7,545.8') or higher. In the [Install settings] menu, set [High altitude] under [Professional settings] to [On] (P147). ■ The Projector Cannot Join the Network Cause The LAN cable (shielded twisted pair) is not connected correctly. The projector has not been on long enough (less than about 40 seconds). The projector cannot join a wireless network. A HDBaseT transmitter or similar device is not on. Countermeasure Check whether the LAN cable (shielded twisted pair) is connected to the projector correctly (P81). Network functions are not available until about 40 seconds after the projector is plugged in. Wait at least 40 seconds, and then try to connect again (P87). Follow the instructions in "Network Setting" (P89 - P90), "Wireless LAN (Wi-Fi)" (P29), and "Detailed settings (wireless)" (P180 - P184) to set up the projector again. In PJ AP mode, try changing the wireless channel on the projector (P180 - P184). In infrastructure mode, try changing the wireless channel on the access point. If connection is still not possible, contact the Canon Customer Support Center. Check the power of the HDBaseT transmitter. Maintenance / Product Specifications / Troubleshooting Troubleshooting 229
