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.
<0°C (<32°F)
>50°C (>122°F)
There are no user-replaceable parts within the Vehicle
Adapter, so do not open the Adapter case. The Vehicle
Adapter is internally protected. It resets automatically if
there is a power fault.
Do not use the Vehicle Adapter to charge the computer
battery overnight. Pull the lever out to turn off Vehicle
Cradle charging at the end of each work day to prevent
draining the voltage in your vehicle's battery below
starting levels.
1. Insert the Vehicle Adapter's power cord into the power port on
the side of the T5200 computer.
