*1 This is the continuous usage time with the operation confirmation LED and vibration function turned off, with the buzzer turned on (with low volume), with the backlight turned on (with low luminance), at normal temperature, and when barcode reading is performed and round trip wireless communication is made once per 20 seconds.
*2 When the main battery is not attached or has no remaining charge.
*3 In a low-temperature environment, the lithium ion battery’s continuous usage time decreases. Be sure to check operations before using the product.
*4 This is a test value. The value is not guaranteed.
