Power cable

The power cable has the following wires and fuses:
• +12 V, car battery +, red (1)
• Ground, car battery -, black (2)
• Car radio mute, yellow (3)
• Car ignition sense, blue (4)
• 2 A fuse (5)
• 1 A fuse (6)
To connect the power cable, do as follows:
1. Connect the black wire to the vehicle ground.
2. Plug the yellow wire into the mute connector of the car radio.
When a call is answered, the car kit switches the yellow wire to ground,
muting the car radio. When the call is ended, the yellow wire is separated
from ground, and the car radio is unmuted.
If the car radio does not have a mute connector, this wire can be left
unconnected. In this case, the car radio is not muted automatically when you
answer a call.
Alternatively, an additional relay can be used to mute the car radio and to
connect the car kit directly to the car speakers. The mute signal is used to
switch the relay.
3. Connect the blue wire to the ignition sense line of the car using the supplied
1 A fuse.
Some vehicles do not support the ignition sense connection. In this case the
blue wire can be left unconnected but the car kit does not switch off
automatically when the car ignition is turned off.
When the ignition sense wire is not connected, the car kit automatically
switches off after two minutes if it is not connected to the phone to prevent
accidental draining of the car battery.
