126Solving Problems
■Make sure the audio cable is connected securely at both ends. For 
computer audio, connect the cable to your computer’s headphone jack or   audio out jack.
■Make sure the volume control on your computer is not turned all 
the way down or muted. In Windows, you may be able to use the 
volume control in your Windows system tray (lower right corner 
of the screen). On a Mac, you may be able to adjust the volume 
from your menu bar (top right corner of the screen) or via the 
volume control function keys. 
■If you are using a microphone connected to the projector’s Mic 
port, make sure the cable is connected correctly and the 
Mic 
Input Volume
 option on the Settings me nu is adjusted correctly. 
See page 94 for more information.
Solving Network Problems
You can’t display an image using Quick Wireless 
Connection.
You may need to restart your computer to connect.
You can’t connect to the projector using NS Connection.
■Make sure the network cable is  connected, as described on 
page 54.
■If you are using the optional wireless LAN module, make sure it is 
installed correctly in the proj ector, as shown on page 57.
■Restart your computer.
■Make sure your projector and computer are configured correctly; 
see page 62 (Ad Hoc mode) or page 68 (Access Point mode).
■If you are using the optional wireless LAN module, make sure 
that you have sufficient wireless signal strength (above 50 
percent). On a Mac, check the AirPort icon on the Mac menu 
bar. In Windows, see the documentation for your computer’s 
wireless card or adapter for details. 
						

							
Solving Problems127
■Make sure you aren’t projecting one of the NS Connection 
configuration screens. (You should see a message that the 
projector is ready to connect.) If you have to exit a configuration 
screen, restart NS Connection.
■If the projector is configured for Access Point mode and you’re 
using DHCP, allow time for your pr ojector to appear. It takes the 
server a little while to pick up the IP address.
■If you’ve changed any settings for  your projector or network, or 
restarted your computer, allow a minute or two for the 
connection to appear. If you’re us ing AirPort, try turning AirPort 
off and then on again.
■Make sure that you’re trying to connect to the right network. In 
Windows, verify that you’ve enabled your computer’s connection 
to the access point (see page 74) or that your wireless card or 
adapter is enabled and its SSID is set to match the projector’s 
SSID (see page 66). On a Mac, click the AirPort icon at the top of 
your Mac desktop to make sure AirPort is turned on and the 
projector’s SSID or your Ai rPort network is selected.
■If you have an access point or AirPort base station and you’re not 
using DHCP, check your projector’s IP address on the Access 
Point mode advanced settings screen. The first three segments of 
the IP address should be identical to the first three segments of the 
IP address of your access point or base station. The last segment of 
the projector’s IP address should be close, but not identical, to the 
last segment of the IP address of  the access point or base station. 
■If you’re not using DHCP, check your projector’s Gateway 
address on the projector’s Access Point mode advanced settings 
screen. It should be identical to the IP address for your access 
point or AirPort base station.
■If you’re using a projector keyword, it changes each time you turn 
the projector off and then on again. Check the projector’s 
keyword on the LAN standby screen and enter it at the prompt. 
						

							
128Solving Problems
■If you’re using AirPort, check the configuration of your network. 
Start the AirPort Admin utility, select your base station, click 
Configure and click Show All Settings. Click the Network 
tab. If you set up your projecto r to connect in DHCP mode, turn 
on 
Distribute IP Addresses and Share a Single IP Address. 
■If you’re using AirPort and DHCP is turned off on your 
projector’s Access Point mode advanced settings screen, make sure 
Distribute IP Addresses is off. 
■If you’re using Access Point mode and you’re connecting to the 
wrong network, you may be experiencing signal interference from 
another network. Try resetting your access point or base station, 
then restart NS Connection.
■If you’re using AirPort, the pr ojector’s SSID should match the 
AirPort network name, not the name  of the AirPort base station. 
To check the network name, start the AirPort Admin utility, 
select your base station, and click 
Configure. Then click Show 
All Settings
. The network name appears on the AirPort tab.
■If you’re prompted for a passwo rd when you connect, enter the 
WEP encryption key (if you’re using WEP encryption).
You are not receiving mail  when a projector problem occurs.
■Make sure the Mail settings are correct in the Network menu. For 
details, see page 84.
■To receive mail notification when the projector is in standby 
mode, you need to set 
Standby Mode to Communication On 
in the Extended menu. See page 101. 
						

							
Solving Problems129
Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 30. 
■Make sure you are within about 20 feet (6 meters) of the projector 
and within range of the projector’s front or back sensor 
(approximately 30° to the left or right and 15° above or below).
■Dim the room lights and turn off any fluorescent lights. Make 
sure the projector is not in di rect sunlight. Strong lighting, 
especially fluorescent lights, may affect the projector’s infrared 
receivers. Also, turn off any nearby equipment that emits infrared 
energy, such as a radiant room he ater. To avoid interference, you 
can also turn off the projector’s front or back sensor with the 
Remote Receiver setting (see page 94), but this may limit where 
you can use the remote control.
■Make sure the projector’s sensors have not been turned off with 
the 
Remote Receiver setting (see page 94).
■If any buttons are held for longer than 30 seconds, the remote 
enters sleep mode. Release any butt on that is held to wake the 
remote. 
■If you’re using the remote control as a wireless mouse, make sure 
the 
USB Type B setting in the Extended menu is set to Wireless 
Mouse 
(see page 101).
