Chapter 7 - Troubleshooting

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 cannot connect when dialing.

•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.

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, and the liquid crystal display (LCD) should light. If the LEDs and LCD remain off, the modem is probably not receiving power.

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

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

•Make sure the transformer 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 transformer module to another outlet on the power strip.

•Test that the outlet is live by plugging another device, such as a lamp, into it.

•The modem or transformer module may be defective. If you have another Multi-Tech modem, try swapping modems. If the problem goes away, the first modem or transformer module may be defective. Call Technical Support for assistance.

CAUTION: Do not under any circumstances replace the transformer module with one designed for another product; doing so can damage the modem and void your warranty.
