*1 The number of displayable characters is the maximum value when the status display is not visible. If the status display is shown, the number of vertically displayed characters with a 16-dot font is 2 lines or 1 line with a 24- or 32-dot font.
*2 Operation confirmation with a KEYENCE device uses the following standard codes: QR and DataMatrix (2D codes), and CODE39 and CODE128 (barcodes).
*3 This is the continuous usage time for round-trip wireless communication when code reading is performed 1 time every 20 seconds at normal temperatures with the operation confirmation LED and vibration function turned off, the buzzer turned on (at a low volume), the backlight turned on (at low brightness), and the operation speed set to standard.
*4 When using the product wirelessly, we recommend that you keep the temperature between -5 and +0 °C and that you keep the remaining battery power at 3.
*5 This is a test value and is not guaranteed.
