When Unable to Successfully Read Codes
Cause
Countermeasure
Change the BHT scanning angle and try
again.
Specular
reflection
When the light is focused on the printed
surface of the code from directly above,
the BHT may not read the code due to
specular reflection.
Scanning may be unsuccessful if it is
too close to or too far from the BHT
reading window, even when the code is
within the read area.
Move the BHT slowly toward or away
from the code and try again.

curvature
Scanning may be unsuccessful if the
code surface is curved.
Scan the barcode at the center of the
barcode reading window.
Code
surface dirt
Scanning may be unsuccessful if its
surface is dirty.
Wipe the dirt from the code and try again.
Blow any dust away with an airbrush, and
then gently wipe the reading window with
a cotton swab or similar soft object.

Battery Power Level Indicator
The battery power level can be checked at the icon that displays in the task tray.
The battery power displays in four levels. The battery power level indicator is a guideline to notify the
operator to charge the battery promptly when discharged.
: Sufficient battery power remains
: The battery power is partially depleted. Charge promptly.
: The battery power is almost fully depleted and should be charged immediately.
: The battery power is fully depleted. Charge immediately or replace with a fully charged battery.
Battery Service Life
The battery is a consumable part. And it should be replaced upon the earlier of one year or after being
charged approximately 300 times. The performance of the battery’s lithium-ion battery will deteriorate
gradually with repeated charging and discharging, even during normal use. When the battery operation
time becomes shorter even after charging for the specified length of time, replace the battery with a
new one.
