2. Provide a Reliable Power Source
If you have not already done so, install the terminal hardware and provide a reliable power
source, as described in Chapter 2. If the terminal is mounted on a vehicle, it can remain
mounted as long as the internal battery is fully charged (see page 2-8) and you can position
it close enough to the Host PC for the cables to reach. Otherwise, remove it from the vehicle,
position it on a workbench and provide operating power with a Symbol AC Universal Power
Supply.
Note:
If there is a power interruption during the file transfer process, restore
the power and start again at step three (Prepare the Terminal for
Transferring Files).
3. Prepare the Terminal for Transferring Files
This section describes how to run the Program Loader utility on a VRC 6940 terminal, so the
terminal can receive files transferred from a Host PC. To set up the terminal:
1. Boot the VRC 6940 into Command Mode:
a. With the terminal in suspend, press and hold
the A and D keys.
b. Press and release the ON/OFF key.
c. Release the A and D keys.
2. The terminal boots to the Command Mode
screen, shown in Figure 4-4.
