MultiModemDSVD User Guide 5 Solving Problems
49
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. How-
ever, 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 before 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, the 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.
If the power supply is plugged into a power strip, make sure the power strip is
plugged in and its power switch is on.
Make sure the power supply module is firmly connected to the modem and to
the wall outlet or power strip.
If the power strip is on and the modem switch is on, try moving the modem
power supply to another outlet on the power strip.
Test that the outlet is live by plugging a lamp into it.
The modem or power supply may be defective. If you have another Multi-Tech
modem, try swapping modems. If the problem goes away, the first modem or
power supply may be defective. Call Tech Support for assistance.
CAUTION: Do not under any circumstances replace the power supply module with
one designed for another product, as it can damage the modem and void your warranty.
