■ The Projector Cannot Join the Network
■ You Cannot Operate the Remote Control
Cause Countermeasure
The LAN cable (shielded
twisted pair) is not
connected correctly.
Check whether the LAN cable (shielded twisted pair)
is connected to the projector correctly (P83).
The projector has not
been on long enough
(less than about 40
seconds).
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
(P89).
The projector cannot join
a wireless network.
Follow the instructions in “Network Setting” (P91 –
P92), “Wireless LAN (Wi-Fi)” (P30), and “Detailed
settings (wireless)” (P189 – P193) to set up the
projector again. In PJ AP mode, try changing the
wireless channel on the projector (P189 – P193). In
infrastructure mode, try changing the wireless
channel on the access point. If connection is still not
possible, contact the Canon Customer Support
Center.
A HDBaseT transmitter
or similar device is not
on.
Check the power of the HDBaseT transmitter.
Cause Countermeasure
Batteries are not
installed properly or they
have run out.
Check whether batteries are installed correctly. If
batteries are installed correctly, replace them with
new batteries (P40).
You are operating the
remote control from the
outside of the remote
control operating range.
Check whether you are operating the remote control
within the remote control operating range of the main
unit of the projector (P41).
There is an obstacle
between the projector
and the remote control.
Remove the obstacle between the infrared remote
receiver of the main unit of the projector and the
remote control or point the remote control in an
obstacle-free path.
You are operating the
remote control in an
unsuitable operating
environment.
Check whether the infrared remote receiver of the
main unit of the projector is exposed to direct sunlight
or strong light of lighting apparatus (P41).
The channel setting of
the remote control does
not match the setting of
the projector.
Check whether the channel setting of the remote
control has been changed. You can check the
[Remote control channel] setting in the [System
settings] menu (P168).
