If the CASSIOPEIA does not respond when you briefly press the Power button, press and hold the
button for a full second. If that does not work, try the following steps, performing the next step
only if the one you just performed did not solve the problem.
1. Plug the CASSIOPEIA into AC power.
2. Recharge the battery.
3. Adjust display brightness. While holding down the Power button, press the right or left cursor
buttons to adjust brightness.
4. Adjust display contrast. While holding down the Power button, press the up or down cursor
buttons to adjust contrast.
5. Reset the CASSIOPEIA. See “To reset your CASSIOPEIA” in the Hardware Manual.
Screen is dark
Prolonged exposure to direct sunlight may cause your CASSIOPEIA screen to temporarily
darken. This is normal for LCD screens and is not permanent.

Slow or no response

Modem connection problems
You may encounter the following problems when using a modem.
Cannot dial out
• Remove your CASSIOPEIA from the cradle or disconnect the cable. You cannot connect using
a modem if your CASSIOPEIA has an active connection with the computer.
• Verify that the modem is firmly seated and connected to your CASSIOPEIA and the telephone
jack.
• Make sure the telephone line is analog. (Analog telephone lines transmit data in analog instead
of digital form. Your home telephone line is most likely analog, while office telephone lines are
often digital.)
• If you create a modem connection for an external modem, select Hayes Compatible on COM1
as your modem. If you are using a modem card, select the modem card as your modem.
• To use an external modem, you need to use a NULL modem cable and appropriate adapters to
connect the external modem to your CASSIOPEIA.
• Make sure the modem is waiting for a dial tone. Make sure the “Wait for tone” option is
selected on the Modem Setup screen of the modem you are using. See “To configure a dial-up
connection setup” on page 56 for more information.
