To check whether the backup battery in the vehicle computer is charged, tap

 icon to display the 

window.

To save battery power, set the vehicle computer to turn off after a specified number of minutes.

The vehicle computer contains an Ignition Sense feature that detects when the ignition switch is turned off and 
shuts the vehicle computer down after a preprogrammed timeout. This feature allows the operator to use the 
vehicle computer for a predetermined time period after the ignition switch is turned off, then shuts the vehicle 
computer down automatically to prevent over-discharge of the forklift battery. The timeout period is adjustable by 
the user. The normal current draw of a suspended vehicle computer is approximately 500mA. When the vehicle 
computer shuts down using the Ignition Sense feature, current draw is reduced to approximately 5 mA. This feature 
provides the automatic shutoff functionality of an external relay, without requiring an actual relay and has the added 
benefit of allowing the user to work for a preset time period before shutting down.

The power cable must be connected to the ignition switch. See 

 for information on 

connecting the power cable to enable the Ignition Sense feature.
