Single unit operation of the powered subwoofer unit (HTZ-SW7)
(1) When the display unit is connected
When the display unit is connected, there are no other special connections.
The display unit has a remote control light receiver.
(2) When the display unit is not connected
When the display unit is not connected, the "remote control light reception jig GGF1270" must be connected. Please connect it to the point
shown in Fig. 3.
Cautions for making service connections
When power is to be supplied from an external power supply and when the relay is to be short-circuited forcibly, always
disconnect the system cable between the DVD center unit and the subwoofer to prevent equipment breakage.
When the DVD center unit and the subwoofer both are present at the time of servicing, servicing in normal mode (user used
condition) is recommended except for DVD test mode. (Test modes other than the DVD test mode are not supported when
both units are connected.)
