The speaker volume can be set by scanning the following QR Code symbol only. No "Start setting" or "End
setting" QR Code symbol is required to be scanned.
Adjusting the speaker volume
Scanning this QR Code symbol cycles the speaker volume through High, Medium and Low. The factory default is
High.
This QR Code symbol applies only to the speaker beep. Adjusting the playback volume of audio data files requires
