Base Button
The Base contains a button which is used primarily to perform a paging function. Pressing the 
button causes a sound signal to be emitted by all scanners linked with this Base, as long as the  
scanner is awake (see Powerdown Timeout on page 266) and reception is enabled (see Sleep 
Mode Timeout on page 94). The button can also be used to "force device connection" via the 
Datalogic Aladdin Software tool (available for free download from the Datalogic website). See 
the Aladdin Online Help for 
details.
