and the speakers. Check the condition of your speakers care-
fully- connecting this unit to old or degraded speakers may re-
sult in a fault which will damage the audio IC and invalidate the
warranty.
• If this unit is installed in a vehicle that does not have an ACC
(accessory) position on the ignition switch, the red lead of the
unit should be connected to a terminal coupled with ignition
switch ON/Off operations. If this is not done, the vehicle battery
may be drained when you are away from the vehicle for several
hours.
• Secure the wiring with cable clamps or adhesive tape. To pro-
tect the wiring, wrap adhesive tape around them where they lie
against metal parts. To avoid short-circuiting, cover all discon-
nected lead with insulating tape. There is a possibility of short-
circuiting if the leads are not insulated.
• Route and secure all wiring so it cannot touch any moving
parts, such as the gear lever and handbrake. Do not route wir-
ing in places that get hot, such as near the heater outlet. If the
insulation of the wiring melts or gets torn, there is a danger of
the wiring short-circuiting to the vehicle’s body.
• Don’t pass the yellow lead through a hole into the engine com-
partment to connect to the battery. This will damage the lead’s
insulation and cause a very dangerous short.
• Do not shorten any leads. If you do, the protection circuit may
fail to work when it should.
• Never feed power to other equipment by cutting the insulation
of the power supply lead of the unit and tapping into the lead.
The current capacity of the lead will be exceeded, causing over-
heating.
• Since a unique audio I/C circuit is employed, never wire so
the speaker leads are directly grounded or the left and right
– speaker leads are common.
• When this product’s source is switched ON, a control signal
is outputted through the orange lead. Connect to an external
power amp’s system remote control or the car’s Auto-antenna
relay control terminal (max. 300mA 12 V DC). If the car features
a glass antenna, connect to the antenna booster power supply
terminal.
• When an external power amp is being used with this system,
do not connect the orange lead to the amp’s power terminal.
Likewise, do not connect the orange lead to the power terminal
of the auto-antenna. Such connection could cause excessive current
drain and a major malfunction. Refer to the relevant owner’s manual
