Troubleshooting
If you encounter a problem, please review the items in the following
checklist. Also be sure to thoroughly check all other connected components
such as speakers, receiver/amplifier/preamp, VCR, TV, CD player, etc.
Problem Possible Cause and Solution
Power does not come on Check line cord to ensure good connection to the AC outlet and to the
receptacle on the CP-3 rear panel. Check to make sure that the CP-3 rear
panel power switch is ON.
Input level meters not functioning Check to make sure that "LEVEL METERS" (in the DISPLAY ADJUST
sub menu of the Setup menu) is turned ON.
Make sure CP-3 VOLUME is above -54dB.
Make sure that the correct input is selected.
No audio Check input and output connections. They may be reversed relative to
the IN and OUT jacks of your receiver/amplifier/preamp or other
source.
Remote control not working Check batteries to be certain that they are inserted correctly with proper
polarity. Make sure that the infrared sensor on the CP-3 front panel is
not obstructed. Try using the other remote. If neither is working,
the problem is internal. See "If all else fails..." on the following page.
"Wrong remote" message The CP-3 recalls which remote (Standard or Expanded) was last used to
turn it on. Turn the CP-3 off, then back on with the remote you wish to
use.
No output Make sure that signal is coming into the CP-3 by observing the Input
Level meters. Increase VOLUME using the remote control and check
Front/Back and Left/Right BALANCE.
Check the CP-3 MUTE controls to make sure they are not engaged.
Check all other equipment settings and connections and verify that the
amplifiers being fed by the CP-3 are operational.
Remember that the CP-3 mutes the output to any speakers which are
not configured in the Setup menu. If speakers are added to (or removed
from) your system, the Speaker Configuration menu must be altered
accordingly.
Center Channel only plays Check to see if your HiFi VCR has dropped out of tracking — readjust.
Your VCR Stereo/Mono/L-R switch may be in the wrong position —
set it to Stereo.
Muffled sound in L&R channels When no center channel is used, CENTER must be configured for
NONE in the Configuration menu.
Center channel sound muffled The center channel amp may be connected to the subwoofer jack on the
CP-3 rear panel. Reconnect to Center Output jack.
