DC Power Cable Installation
Installation Planning
The 3-meter (10-foot) DC power cable shipped with the terminal should be long enough to be
installed in most vehicles. Take the following precautions before you begin:
1. Whenever possible, avoid routing the cable above the catalytic converter.
2. Make sure that the power cable never rests on sharp edges.
3. Use grommets whenever a cable has to pass through a hole in a metal panel.
The following table lists power cables available for this terminal:
In a vehicle with an airbag, make sure that the mounting
location of the mobile terminal, or of any terminal
accessory, is not in the deployment path of the air bag.
Uninstaling the radio
OPTION 1:
Before disconnecting the 13.2 V main power supply from
the radio:
1. Switch off the radio.
2. Wait for a minimum of 4 seconds after the radio switch
is released.
3. Disconnect the 13.2 V main power supply.
OPTION 2:
Turn off the main power supply WITHOUT switching OFF
the radio.
This terminal must be operated only in negative ground
electrical systems. Operating the terminal on a positive
ground system will cause the cable fuse to short-circuit.
Check the vehicle ground polarity before you begin the
installation.
