2.3 Activating the System
The EC400 / EC450 system has a shutdown feature that should be used when the vehicle is in storage
or is not being used for long periods of time. This allows the leisure electronics to be turned off when
not required to save battery power. When in the off state the alarm and tracking system supplies are
still active, most other supplies are turned off.
Before using the system please ensure the shutdown switch is in the system on position (button in).
