Connecting the System
Before installing the unit
• This unit is for vehicles with a 12-volt battery and negative grounding. Check the battery
voltage of your vehicle before installation.
To prevent damage
• When disconnecting a connector, pull the connector itself. Do not pull the lead, as you
may pull it out of the connector.
• This unit cannot be installed in a vehicle that does not have an ACC (accessory) position
on the ignition switch.
• To avoid short-circuiting, cover the disconnected lead with insulating tape. It is especial-
ly important to insulate all unused speaker leads, which if left uncovered may cause a
short circuit.
• Attach the connectors of the same color to the corresponding colored port, i.e., blue con-
nector to the blue port, black to black, etc.
• The black lead is ground. Please ground this lead separately from the ground of high-
current products such as power amps.
Do not ground more than one product together with the ground from another product.
For example, you must separately ground any amplifier unit away from the ground of
the Hide-away unit. Connecting grounds together can cause a fire and/or damage the
products if their grounds became detached.
• Refer to the owner’s manual for details on connecting the power amp and other units,
then make connections accordingly.
• When replacing the fuse, be sure to use only a fuse of the rating prescribed on the fuse
holder.
• Since a unique BPTL circuit is employed, do not directly ground the
≠
side of the
speaker lead or connect the
≠
sides of the speaker leads together. Be sure to connect the
≠
side of the speaker lead to the
≠
side of the speaker lead on the display unit.
• If the RCA pin jack on the unit will not be used, do not remove the caps attached to the
end of the connector.
•
When the auto antenna function is used by connecting the blue lead to the vehi-
cle with the auto antenna function, either turning off the ignition switch or
detaching the front panel will retract the auto antenna of the vehicle.
