3.2 Trouble shooting
Please contact the dealer or call at the service center for usage or post-sale service of
the CRUISER (XCM-2000) cable modem. We advise you to check the followings
beforegivingusacall.
•On unpacking the CRUISER(XCM-2000)cable modem package,You can request the
dealer to exchange the damaged or lost contents. ( damaged adapter, damaged
XCM-2000,defective contents,etc.)
•You must check the followings first if LEDs do not turn on at all or do not normally
operatein spiteof acorrect connection ofthe adapter.
-There may be a problem with the power connector or power adapter.
Therefore, you need to make sure that the power plug is correctly
connectedtothepowerconnector.
Note:Regardingpowersupply of XCM-2000, youdonotneedtoworryaboutwhethertoset it
to110Vor 220V nortoperformanyuserdefined special operations.
•You cancheck thefollowings for badconnection.
- Theremaybe a problem with thecableif‘RDY’and/or‘SYNC’oftheLEDs
do not turn on. You must check if the coaxial cable is correctly connected
and, if so, you should wait for minutes after pushing the‘RESET’key.
Nevertheless, if those LEDs‘RDY’and‘SYNC’do not turn on, you must
haveitcheckedbytheserviceprovider.
- Ifyouarenot able to access Internet despitethat‘RDY’and‘SYNC’areon,
you can check the Ethernet port. Then, you must verify that your PC and
LAN card or the HUB port in use is on and check the Ethernet cable over
again. If you are still not able to access Internet, you can check if the LAN
card or HUB is correctly set up. Also, you may be able to get help from the

If the CRUISER (XCM-2000) cable modem does not properly work in spite of your
actions according to the instructions above, you can disconnect the power adapter
forabout5~10secondsandthenconnect it to the modem again.
Since there are no further complicated items with the CRUISER (XCM-2000) cable
modem that users have to understand themselves besides connection of the power
adapteror cables, you wouldbetter get help (post-saleservices) from the dealer for
