Introduction
Your MultiModemZDX modem was thoroughly tested at the factory be-
fore it was shipped. If you are unable to make a successful connection,
or if you experience data loss or garbled characters during your connec-
tion, 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 may encounter:
• None of the LEDs light when the modem is on.
• The modem does not respond to commands.
• The modem dials but cannot connect.
• 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.
• Fax and data programs can’t run at the same time.
If you experience problems, please check the following possibilities be-
fore calling Technical Support (see Appendix C).
None of the LEDs Light When the Modem Is On
When you turn on the ZDX, the LED indicators on the front panel should
flash briefly as the modem runs a self-test. If the LEDs remain off, the
modem is probably not receiving power.

Make sure the modem’s power switch is on, especially if you nor-
mally turn on the modem by turning on a power strip.

If the power supply is plugged into a power strip, make sure the
power strip is plugged in and its power switch is on.
