7 Solving Problems

Introduction

Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a successful connection, or if you experience data loss or garbled characters during your connection, it is possible that the modem is defective. However, it is more likely that the source of your problem lies elsewhere. The following symptoms are typical of problems you might encounter:

•None of the LEDs light when the modem is on.

•The modem does not respond to commands.

•The modem dials but is unable to make a connection.

•The modem disconnects while online.

•The modem cannot connect when answering.

•File transfer is slower than it should be.

•Data is being lost.

•There are garbage characters on the monitor.

•The modem doesn’t work with Caller ID.

•Fax and data software can’t run at the same time.

If you experience problems, please check the following possibilities be- fore calling Technical Support (see Appendix D).

None of the Indicators Light

When you turn on the modem, the LED indicators on the front panel should flash briefly as the modem runs a self-test. If the LEDs remain off,

4the modem is probably not receiving power.

Make sure the modem’s power switch is on, especially if you normally turn on the modem by turning on a power strip.
