Turn the hand-held on. Wait until the unit has booted up completely.
Important: If an aiming dot is available on the installed scanner, the dot will
be enabled for a configurable time period (including off), after
which normal scanning begins. Refer to “Dot Time (msec)” on
page 137 for details.
Double-clicking the trigger will override the aiming delay and
initiate an immediate scan. Note that the aiming dot is standard
on long-range and high visibility internal scanners.
Aim at the bar code and press the scan key or the trigger. A scan beam and a
warning indicator appear until a successful decode is achieved or six
seconds have elapsed.
