Phone Connection
For voice-only calls, you can optionally plug a telephone into the modem’s PHONE
jack.
Microphone Connection
Plug the microphone plug of the supplied headset into the MIC jack on the side of
the modem. Optionally, plug an unamplified microphone into the MIC jack. The mi-
crophone should have a 1/8-inch mini plug.
Speaker Connection
Plug the speaker plug of the supplied headset into the SPKR jack on the side of the
modem. Optionally, use a 1/8-inch-plug male-to-male stereo patch cord to connect
the SPKR jack on the side of the modem to the LINE IN jack on your sound card.
If you do not have a sound card, you can plug an amplified speaker directly into the
SPKR jack.
Power Connection
Plug the power supply module into an AC power outlet or power strip. Plug the
power supply’s cable into the PWR jack on the modem.
Note: Use only the power supply supplied with the modem. Use of any other power
supply will void the warranty and could damage the modem.
Power-On Test
Test the modem by turning it on (a power switch is located on the right side). When
you apply power, the modem performs a diagnostic self-test, indicated by several
indicators flashing for a second or two, after which the 56 indicator should light. If
this does not happen, check that the power switch is on, the power supply is solidly
connected, and the AC outlet is live. If these measures do not work, see Chapter 6,
“Solving Problems.”
Surge Protectors and Lightning
Because of power surges and other transient voltages on power and telephone lines,
we recommend that you plug the modem into a surge protector rather than directly
into a wall outlet, preferably a surge protector that provides protection against elec-
trical spikes on the telephone line as well as on the power line. Please note, however,
that not even a surge protector can guard against damage from a nearby lightning
strike.
