1.3 Modem Rear Panel

Located on the modem rear panel are the power switch, power socket,
volume control, RS-232 connector, and two modular jacks, as shown
in the schematic.

The power socket is labelled 9V or 12V AC (optional) and corresponds
with the power supply unit packaged with your modem. Never use a
non-specified power supply unit, as it might damage your modem.

To turn on the modem, toggle the power switch to ON. Likewise, to
turn off the modem, toggle the power switch to OFF. Always turn your
computer on prior to turning on your modem and turn off your modem
prior to turning off your computer.
