2 Installation

Step 1: Mount the Feet

The modem comes with a strip of self-adhesive plastic feet, which you can optionally mount on the bottom of the modem. To install the feet, simply peel them from their paper strip and press them into the recesses on the bottom of the modem.

Step 2: Change the Speaker Jumper (MT5600DSDV only)

This step is required only if you intend to connect a monophonic speaker to your mo- dem. (This step is not required for stereo speakers or for the included headset.) If you do not intend to connect a monophonic speaker to your modem, skip to Step 3.

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 RS232 connector to ensure that there is no voltage difference between you and the modem.
