How do I Enter or Exit Shipping Mode in the Vantage Lite?
Enter Ship Mode
If you ever have to ship the Vantage device for servicing, always put the device in Shipping Mode. This will preserve the batteries while the device travels and prevent accidental activations during transit.
Go to the Toolbox by selecting the Tools 
Key on the top of the EssenceVT case. Next select the Maintenance Menu then Enter Shipping Mode.
You see a message asking if you want to enter Ship Mode now. Answer YES or NO. (NO is the same as Cancel.)
If you answer YES, unplug the battery charger. Once the charger is unplugged, your device will enter Shipping Mode.
Exit Shipping Mode:
Plug in your battery charger. Then press the ON/OFF button on the top left front of the case.
or if the charger is not available, press and hold the ON/OFF button 
on the front of the case for 10 seconds.
Let go of the button.. The device is released from Shipping Mode after selecting I Agree to the software license agreement.
