Ignition Sense IGNS
The ignition sense feature prevents your car kit from draining the car battery by executing
an auto power off 20 seconds after the ignition key has been turned off. The blue cable
from PCH-4J is used for the ignition sense feature. The use of ignition sense is
recommended to prevent accidental draining of the car's battery. The cable is connected
EN
via a 1-A fuse to a 12- V supply that is controlled by the ignition key. Do not connect it
directly to the high voltage sections of the ignition circuit.
Car Radio Muting CRM
The car kit offers a feature that can mute the car radio automatically during a
conversation. The following is the circuit diagram for CRM.

Another possibility is to use a special muting unit, which mutes the radio by connecting
load resistors to the speaker lines of the car radio.
Antenna Motor Control AMC
The antenna motor control may be used to turn different devices on and off. The
maximum output current is 200 mA; therefore, for example, a motorized antenna must be
controlled via a relay, see diagram below.

All installations should take into account any special requirements of the customer.
However, should the customer require an installation that is illegal or unsafe these facts
must be pointed out to the customer and a policy of non-compliance adopted.
