Before placing an repair order
Please make sure of the following:
Symptom Please check:
The computer does
not recognize the SD
card.
Writing cannot be
performed.
The image from the
PC is not displayed.
The PC does not
recognize the
wireless card.
Transfer rate has
become lower.
"Projector search" of
the Wireless Manager
2.0 does not detect
the projector.
• Is the PC card adapter inserted into the PC card slot of the PC until it
reaches the end?
• Is the SD card inserted into the SD card slot of the PC card adapter
until it reaches the end?
• Is the driver installed?
• Are there sufficient IRQ (interrupting signal) numbers? (Refer to the
online help of Windows.)
• Is the write-protect switch of the SD card set to "LOCK"?
• Is the external video output of the notebook computer properly
selected? (In some cases, the setting of the output is changed if Fn
and F3 buttons are pressed simultaneously. Since this depends on
the model, refer to the instruction manual supplied with your PC.)
• Is the wireless card inserted into the PC card slot of the PC until it
reaches the end?
• Is the driver installed?
• Are there sufficient IRQ (interrupting signal) numbers? (Refer to the
online help of Windows.)
• If WEP is enabled, transfer operation takes a longer time because
the image data needs to be converted.
• If another wireless device uses the same channel, the transfer rate
may become lower. Select other channel for setting.
• Immediately after the projector is turned on, it is on the way to establish
the network communication. Perform the search again after a while.
• Check whether the distance is too far between the PC and the projector,
or if any obstacle between is making the radio waves unstable.
• Make sure that the IP address and the subnet mask are correctly
assigned.
• Is TCP/IP installed in your personal computer?
• Does the WEP setting correspond with that of the projector?
Communication with the projector cannot be established if the WEP
function was enabled when a third-party wireless card was used or
the access point was used. Disable the WEP function.
• In the Ad Hoc mode, use the same channel setting for the projector
and the PC.
• In the Infrastructure mode, use the same setting for the projector and
the PC as the access point "SSID". Alphanumeric characters (case
sensitive) can be used for an SSID. Make sure that the user is not
using the function for controlling PCs that can communicate with the
access point.
• In the PEER-TO-PEER mode, use the same setting for channel and
SSID of the projector and the PC.
• Is any network device other than the wireless card enabled? Check
with the device manager of Windows.
• Is any proxy-client software operating? Disable it when
communicating with the projector.
• When a projector LAN card is used, ensure that the projector and the
PC are directly connected with a cross cable.
If connection is made between the projector and the PC through a
hub or other relaying device, follow the connection method of the
projector.
