If you experience problems with your 2743, please check the items listed below.
1. Verify that the AC adapter is plugged into a working outlet. The outlet may be
verified by plugging a lamp or other device into it.
2. Verify that the AC adapter is plugged securely into the 2743. This may be verified by
checking that the 2743 status indicator is blinking.

switch settings.
