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.
