Aiming
Product Reference Guide 13
Do not hold the scanner perpendicular to the bar code when scanning. Laser light reflecting
directly back into the scanner from the bar code can result in specular reflection, which can in
turn cause difficulties with decoding. Tilt the scanner to avoid the dead zone (indicated by an
‘X’ in
Figure 6 ) up to 65 degrees upwards or downwards.
