Manual
When turn on scanner I get rapid beeping. Seems no customer service exists anymore. Has anyone experienced this ?
Look through here:

It MAY be this:
"Turning The Keytone Off/On Contents
You have the option of turning the key conformation tone off or on (to confirm that the keys have been pressed). The keypad area is kind of small so some of us with big fingers, afraid that they have pressed more than one key at a time, might appreciate this. This will also kill the annoying 'battery low' beep every 2 seconds.
To turn the Keytone off, turn off the scanner. Turn on the scanner and press 2 while the welcome screen is displayed. Key-tone ON will briefly appear.
To turn the Keytone on, turn off the scanner. Turn on the scanner and press 1 while the welcome screen is displayed. Key-tone OFF will briefly appear.
