Mount of bass speaker and VCD
(a) bass speaker
Connect the audio output wires of bass speaker with the sockets in bass speaker correspondingly according
to the wire color (red plugging element should be plugged in red socket, yellow plugging element in white
socket, the grounding wire (black), power wire (yellow) and signal wire (blue) should be fixed at the
corresponding positions (GND
12V
REM) on bass speaker tightly.
(b) multi-disc VCD
The feed cables of VCD main device should be connected as marked, when connecting the plugging element
of wire harness of video camera (CAM) with the plugs on main device (CAM), notice should be taken on the
two arrow marks so as to prevent the plugging element damage; The audio output wire plugging elements (red
and yellow plugs) of bass speaker should be connected with the red and white sockets of mainframe (AV OUT);
the plugging elements of TV receiving input wire of amplifier should be connected with either of the plugging
elements(AV AN) of the mainframe; the plugging element (black and white ACC) of anode wire of power
supply should be connected with the red socket (ACC) of mainframe wire harness; grounding wire plugging
element (black GND) should connect with the black socket of mainframe wire harness; the plugs of audio input
wire of deci-disc data converter should be connected with the red and white socket on mainframe according
to the plugs color (the plugs (red, white CD OUT) of audio input wire of eight-disc box should be connected
with the red, white socket (CD IN) on mainframe according to the plug color, the yellow power wire plugging
element (BATT) should be connected with the yellow power wire socket (BATT) on mainframe, the electric
aerial, plugging elements of control wire of function amplifier should be connected with the electric aerial
(CTL), socket of control line of function amplifier on mainframe. After completing the connection of plugging
elements, wrap the connecting position with adhesive strap in order to prevent those plugging elements from
peeling off, the plugging element of feed cable of TV receiving aerial can connect with any two of the four
holes on amplifier, meanwhile, turn on the switch (with a red indicating lamp) of amplifier when watching the
TV play. When mounting the VCD mainframe, push the wire harness innermost as can as possible so that there
is spacious room for mainframe, then push in the mainframe, notice should be taken not to damage the wire
harness. Fasten the mainframe to the degree that it cannot be pull out by hand after assembling, if it cannot be
clamped tightly, prize out the two clips on the inner sleeve, then fasten the mainframe, and mount on the
external decoration frame finally. When disassembling the mainframe, tear down the external decoration
frame first, then insert the special key into the open grooves at two sides to pull out the mainframe.Body Electric System
