Chapter 2 – Installation

This chapter shows you step-by-step how to set up your Multi-Tech MT9234ZBA modem.

Safety Warnings

•Use this product only with UL- and CUL-listed computers (U.S.A. and Canada)

•To reduce the risk of fire, use only 26 AWG (.41mm) or larger telephone wiring.

•Never install telephone wiring during a lightning storm.

•Never install a telephone jack in a wet location unless the jack is specifically designed for wet locations.

•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

•Use caution when installing or modifying telephone lines.

•Avoid using a telephone during an electrical storm; there is a risk of electrical shock from lightning.

•Do not use a telephone in the vicinity of a gas leak.

•This product must be disconnected from the telephone network interface when servicing.

Step 1: Change the Internal Jumpers

This step is required only if:

•You intend to use the modem on a leased line.

•You intend to add a monophonic external speaker to your modem with the voice option. No changes are needed for stereo.

This will require you to open the modem and move one or more jumpers on the modem’s printed circuit board. Warning: The following procedure must be performed by authorized service personnel.

Caution: The circuit board can be harmed by static electricity. Before you open the case, touch a grounded object, such as the metal chassis of your computer, to discharge any static electricity in your body, then touch the metal shell of the modem’s RS-232 connector to ensure that there is no voltage difference between you and the modem.

Opening the Modem

1.If the modem is connected, turn it off and remove all connecting cables (including the power and line cables).

2.Turn the modem upside down.

3.On the bottom of the modem are two screws, which hold the case together. Remove both screws and set them aside.

4.Turn the modem right side up.

5.Before touching anything inside the modem case, discharge any static in your body by touching a piece of grounded metal such as the computer chassis. Electrostatic discharge (ESD) is the release of stored static electricity that can damage electrical circuitry or components. Static electricity is often stored in your body, and discharged when you come in contact with an object of a different potential.

6.Perform the procedure below described in this section only at an ESD workstation using an antistatic wrist strap. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal ground screw (lug).

7.Remove the top part of the modem case.

8.To close the modem, reverse Steps 1–5.
