Electrical Accessories

1.  This player is used on vehicles with a 12 V battery and negative ground. If this player is to be installed 

on a vehicle with a 24 V battery, please install voltage reduction equipment.

2.  To avoid short circuiting the electrical system, cut off the battery negative end's connection wire before 

installation.

3.  Please arrange the connection wires at fixed locations, as to make sure they will not make contact 

with any portable parts, such as the parking brake control mechanism assembly, gear lever, the seat's 

fixed track, and so on. Please do not arrange the wires in a heat source area, like near the discharge 

outlet of the heater, etc. Otherwise the heat source will cause the insulating layer to melt or wear out, 

and then lead to a short circuit between the connection wire and the vehicle body.

4.  Do not put the power cord through the mounting hole into the engine box and then connect it to the 

battery. Otherwise it might damage the power cord and then lead to a short circuit between the power 

cord and the vehicle body.

5.  When changing the fuse, please use the specified 15 A fuse. Fuses with an unmatched size will lead 

to abnormal operation, and even damage the player or cause a fire hazard.

6.  Please do not share the player's power supply with other equipment, otherwise it might lead to a 

malfunction due to overloading.

7.  Please wrap up the exposed places of the wire with insulating cement to avoid short circuiting.

8.  Bind up all the connection wires well to avoid any connecting term inal  touching  the  player  or  other 

mental parts of the vehicle body and leading to a short circuit.

9.  When switching the player's power on, the external connection amplifier's controlling signal will output 

through the lead wire P.CONT. If the player is connected with an external connection amplifier, please 

do not connect the lead wire P.CONT to the amplifier's supply terminal, otherwise it will cause a 

malfunction.

10. The player's outputting terminal must not be grounded, otherwise the amplifier may burn out. Please 

do not use a 3-wire type speaker system which shares the ground cable. Please do not connect the 

speaker wire to the vehicle body.

11. The maximum rated power of the speaker connected to this player is 50 W, resistance value is 4 Ω.
