The aiming pattern does not appear
when pressing the trigger. No power to the digital imager
scanner. If the configuration requires a power
supply,
re-connect the power supply.

cable.

medium/short high beep sequence
(power-up beep sequence) more than
once. The USB bus may put the digital
imager scanner in a state where
power to the digital imager scanner is
cycled on and off more than once. Normal during host reset.
Digital imager scanner emits aiming
pattern, but does not decode the bar
code. Digital imager scanner is not
programmed for the correct bar code
type. Program the digital imager scanner to
read that type of bar code. See
Chapter 10, Symbologies .
Bar code symbol is unreadable. Scan test symbols of the same bar
code type to determine if the bar code
is defaced.
The symbol is not completely inside
aiming pattern. Move the symbol completely within
the aiming pattern.
Digital imager scanner emits 4 short
high beeps during decode attempt. Digital imager scanner has not
completed USB initialization. Wait several seconds and scan again.
