manipulatingyourPC.Exercisecautionatalltimeswhen
working with AC powered and static-sensitive equip-
ment. Turn off and unplug your PC before installation.
Dischargeanystaticelectricityfromyourbodybytouch-
inganygroundedmetalsurfaceofthePCsystem,such
as its power supply cover.
1. Turn off and unplug your computer from the AC
outlet.
2. Remove your computer's cover (refer to your
computer's owner's manual).
3. Selectanyavailable32-bitPCIcardslotand remove
the slot cover (refer to Figure 2-3).

4. Carefully slide the PCI internal modem into the slot
you have chosen, applying even pressure until the
modem is completely seated in the slot.
5. Fasten the retaining bracket with the screw from
the slot cover. Make sure the modem is properly
aligned. Store the slot cover for future use.
6. Replace the computer cover and plug in your com-
puter.
7. Connectthetelephonecablefromthemodem'sLINE
connector to the telephone wall jack.
8. Optionally, connect your telephone to the modem's
PHONE connector, a microphone to the MIC con-
nector and a speaker to the SPK connector.
9. Turn your computer on. Your modem is now in-
stalled.

Section Six - Troubleshooting
Thissectiondescribessomeofthecommonprob-
lemsyoumayencounterwhileusingyourmodem.Ifyou
cannotresolveyourdifficultyafterreadingthischapter,
contact your dealer or vendor for assistance.
Modem does not respond to commands.
1. Make sure the modem is not configured with a
conflictingCOMportandIRQsetting(seeSections
2.2-2.5). As an example, your modem can not be
configuredasCOM1ifanotherdeviceinyoursystem
isalsoconfiguredasCOM1.
2. Makesurethecommunicationsoftwareisconfigured
to“talk”tothemodemonthecorrectCOMportandIRQ
setting (same COM port and IRQ setting as the
modem).Yourcommunicationsoftwaremustknow
whichaddressyourmodemisusinginthesystemin

3. Make surethat yourmodem isinitialized correctly.
Yourmodemmayhavebeeninitializedtonotdisplay

Modem does not dial.
1. Make sure the modem is connected to a working
phoneline.Replacethemodemwithaworkingphone
toensurethatthephonelineisworking.
Modem dials but does not connect.
1. Make sure the IRQ setting is identical on both the
modem AND the software. Modem and software
mustbeconfiguredidentically.
2. Makesurethephonelineisworkingproperly.Replace
themodemwitharegularphoneanddialthenumber.
If the line sounds noisy, you may have difficulty
