select a specific option, scan the associated bar code
beginning on page 40.

The host sends a Laser On command. The laser remains on
and decode processing occurs until a good decode, the
Laser On Time-out is reached, or the host sends a Laser Off
command.

The laser remains on and decode processing continues
