LASER TERMINAL
/ IRU 1700
CRADLE
16
The terminal is a Class I laser product conforming
to the strictest laser safety standards.
However, we recommend that you avoid looking
directly into the laser beam emitter, or pointing
the laser beam directly into someone’s eyes.
Fit the bar code in the laser beam from
margin to margin and pass the scanner
downward over the bar code, as shown in the
scan position illustration.
A ‘Good Read’ means that the scanner has
effectively recognised and decoded the bar
code. In most cases, the application program
will provide an indicator signal or a buzzer
signal to indicate a good read to the user.
When the read is incorrect you can try again,
paying attention to the instructions stated
below.
4.3 If you have problems with the read
operation
Change the angle between the bar code
and the terminal.
Change the distance between the bar
code and the terminal.
If the bar code is larger than the laser
beam, try moving the terminal a bit further
away from the bar code.
Please take care of the handling
precautions.
Please make sure that the terminal is
installed according to the installation
instructions.
Never remove the main battery pack
while the terminal is turned on.
Doing so can cause data in the terminal
to be deleted or corrupted.
4.1 Scan Position
When reading a small bar code, decrease the
distance between the terminal and the bar
code. For larger bar codes, position the terminal
so that the bar code fits into the laser beam.
When reading a very high density bar code,
decrease the distance between the terminal
and the bar code. For a low density bar code,
increase the distance between the terminal
and bar code.
4.2 Reading the bar codes
The scanning sequence is defined by the
user’s application. A typical sequence is:
Press the [PW] key to turn power on.
Check the display for the message:
READ BAR CODE
Point the terminal to the bar code and
press the Trigger key.
Point the laserbeam to the barcode as
shown in the scan position illustration.
The barcode will be read and the reading
results will be indicated.
