Hand-Held
 Trigger Mode

Parameter #
138
  (SSI # 8Ah)
This parameter allows you to change your scanner's behavior to initiate a decode.
Choose one of the following to select a trigger mode for the scanner:
  • Standard (Level) - A trigger press activates decode processing. Decode processing continues until the barcode decodes, you release the trigger or the Decode Session Timeout occurs. If the trigger is released before the timeout expires, the decode session terminates and no decode occurs.
  • Presentation (Blink) - The scanner activates decode processing when it detects a barcode in its field of view. After a period of non-use, the LEDs turn off until the scanner senses motion.
  • Auto Aim - The scanner projects the aiming pattern when lifted. A trigger press activates decode processing. After a period of inactivity, the aiming pattern shuts off.
    Then, after an additional time period where no activity occurs, the scanner enters low power mode to conserve battery power, and remains in low power mode until a trigger pull. See Timeout to Low Power Mode from Auto Aim to set this timeout value.
