When the connection is made as in 3 above, the unit's
power will not be linked to the ignition key. For that reason,
always make sure to turn off the unit's power when the
ignition is turned off.
To link the unit's power to the ignition, connect the ignition
cable (ACC...red) to a power source that can be turned on
and off with the ignition key.
1 (Default setting) The A-7 pin (red) of the vehicle's ISO
connector is linked with the ignition, and the A-4 pin (yellow) is
connected to the constant power supply.
2 The A-7 pin (red) of the vehicle's ISO connector is connected
to the constant power supply, and the A-4 pin (yellow) is linked
to the ignition.
3 The A-4 pin (yellow) of the vehicle's ISO connector is not
connected to anything, while the A-7 pin (red) is connected to
the constant power supply (or both the A-7 (red) and A-4

Make sure that the unit is installed securely in place. If the unit is
