Power Cable PCH–4J
The power cable connects the standard handsfree unit HFU–2 to the ve-
hicle's power supply. The red wire must be connected to the + voltage on
the vehicle's power supply via the supplied fused connector. The black
wire must be attached to a good negative GND connection.
The blue ignition sense (IGNS) wire is connected to +12 V voltage con-
trolled by the vehicle's ignition key via the supplied fused connector.
See section "Ignition Sense".
The yellow wire is used for car radio muting (XCRM). The line goes down
to 0 volts during a call. See section "Car Radio Muting".
The green wire is used for motor antenna (AMC). The voltage in this out-
put is +12 V whenever the phone is on. See section "Antenna Motor Con-
trol".

External Mobile Antenna (not supplied)

The cellular phone is designed to operate with a high quality external an-
tenna. However, due to many different types of antennas being available,
an antenna is NOT included as part of this kit. Please, consult the dealer
to find out which is the most suitable antena type for your installation.
