Data Capture 2 - 7
After a programmable time period (see Momentary Trigger Mode Timeout on page 4-16), the aiming dot turns off
and the digital scanner returns to presentation mode, ready to read bar codes without use of the trigger. For beeper
definitions, see Table 2-1.
Aiming in Momentary Trigger Mode
When scanning, the digital scanner projects a red aiming dot which allows positioning the bar code within its field of
view. See Decode Ranges on page 2-8 for the proper distance to achieve between the digital scanner and a
symbol.
Figure 2-5
Imager Aiming Dot
If necessary, the digital scanner turns on its red LEDs to illuminate the target symbol.
To scan a symbol, center the aiming dot on the symbol, in any orientation.
Figure 2-6
Scanning Orientation with Imager Aiming Dot
The digital scanner can also decode with the aiming dot on a symbol but not centered. The top examples in
Figure 2-7 show acceptable aiming options, while the bottom examples may not be decoded.
Figure 2-7
Acceptable and Incorrect Aiming
The aiming dot is smaller when the digital scanner is closer to the symbol and larger when it is farther from the
symbol. Scan symbols with smaller bars or elements (mil size) closer to the digital scanner, and those with larger
bars or elements (mil size) farther from the digital scanner.
The digital scanner beeps to indicate that it successfully decoded the symbol. For more information on beeper and
LED definitions, see Table 2-1 and Table 2-2.
