Removing Power to the Vehicle Computer
If it is required to remove the vehicle computer from a power source (replace a vehicle’s battery):
1. Ensure that all the Forklift Ignition Off wakeup settings are set to No. Tap > Settings > Control Panel >
Power icon > Wakeup tab to view the wakeup settings.
2. Press the Power button on the Quick Access Panel to place the vehicle computer in suspend mode.
3. Turn the vehicle ignition switch to the off position, if applicable.
4. Remove power to the vehicle computer.
5. After re-applying power, turn the vehicle ignition switch to the on position, if applicable.
6. Press the Power button on the Quick Access Panel to resume normal operation.
NOTE 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 (see Ignition Sensing on page 3-17 for setting the timeout value).
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.
NOTE Place the vehicle computer in suspend mode prior to removing power.
