Vehicle Adapter 
The Vehicle Adapter is an optional device that supplies power from the vehicle battery to operate the 
computer and charge the battery installed in the unit. It typically connects to the vehicle battery using the 
cigarette lighter socket.
To prevent possible damage to the battery, the system will not allow the battery to charge at extreme 
temperatures. Be aware of the following charging characteristics, especially if the computer is left 
unattended in a closed vehicle. 
 To connect the vehicle adapter 
1. Insert the vehicle adapter’s power cord into the power port on the back of the computer. 
2. Insert the cigarette lighter adapter into the vehicle’s cigarette lighter socket, turning it slightly to 
make a good connection. 
The power light illuminates to indicate that current is reaching the vehicle adapter. When you 
connect the vehicle adapter, it automatically begins charging the computer’s battery. At moderate 
temperatures, around 21°C (70ºF), the battery will be fully charged in approximately four to five 
hours. However, under extremely cold or hot temperatures, or if the system is on, it will take 
longer to charge the battery (up to 16 hours).
