Troubleshooting
Here is an overview of the most common problems. If you have any further questions please contact your Canton dealer,
call our Service Hotline on [phone] or send us an e-mail at [e-mail].
Problem Possible cause Solution
DM system does not turn
on
1. Power cable not connected to the power outlet and /
or DM system
Check connection
2. The power has not been turned on Switch to “ON”
Sound reproduction too soft 1. Volume of DM system set too low Increase the volume using the “Volume” button
DM system does not
respond to remote control
1. The battery is flat Change the battery
No sound reproduction 1. Sound format of the source device wrongly selected
(Digital input „AUX“)
1. Please check the correct setting of your source device (see Page 6).
„DTS“ or „Dolby Digital“ coded output formats cannot be reproduced
2. Source device not producing any signal 2. Digital output on the source device not activated (please refer to device instructions)
3. Cable not correctly connected / faulty cable 3. Check the connection of the source device to the DM 8.2 and
change the cable where necessary
DM system hums 1. Signal lines from source device to DM system too long Use shorter signal line
2. Signal line used is not fault-protected or the protection
has been damaged (defective)
Change signal line for a fault-protected line
3. Ground loop (ripple pickup) generated A ground loop can be generated when two or more devices connected via a signal
line (cinch) are plugged into separate sockets (e. g. amplifier and computer). Plug all
devices connected to the DM 8.2 into a multiple socket output using safety plugs
4. Another piece of equipment on the same circuit has no
interference suppression (e. g. fridge)
Switch off possible sources of interference to test; unplug the device concerned to see
if the humming noise disappears or connect the source of interference to a different cir-
cuit (L1, L2 or L3). (Where necessary take advice from your electrician.) Insert a special
“ferrite common mode filter” (available from specialist retailers) between the amplifier
and the DM system to eliminate the humming. Turn the power plug round to reduce the
so-called ripple voltage (particularly important if the source device is not earthed)
