Indicators
  
 
When the MS1690 series scanner is in operation, the scanner provides audible 
feedback.  These sounds indicate the status of the scanner.  Eight settings are 
available for the tone of the beep (normal, 6 alternate tones and no tone).  To 
change the tone, refer to the MetroSelect Single-Line Configuration Guide,  
MLPN
 00-02544 or MetroSet2’s help files. 
 
One Beep 
When the scanner successfully reads a bar code it will beep once and the 
white LED will turn on indicating data is being transmitted. 
 
If the scanner does not beep once and the white light does not turn on, then 
the bar code has not been successfully read. 
 
Short Razzberry Tone 
This tone is a failure indicator (see Failure Modes on page 18). 
 
Long Razzberry Tone 
This tone is a failure indicator (see Failure Modes on page 18). 
 
Three Beeps - At Power Up 
When the scanner first receives power it will start an initialization sequence.  
All LEDs (yellow, white, and blue) will light for approximately two seconds then 
start to alternately flash.  When the scanner has finished initializing the LEDs 
will stop flashing and the unit will beep three times indicating that the scanner 
is ready for use. 
 
Three Beeps - Configuration Mode 
When entering configuration mode, the white LED will flash while the scanner 
simultaneously beeps three times.  The white and blue LEDs will continue to 
flash while in this mode. Upon exiting configuration mode, the scanner will 
beep three times, and the LEDs will stop flashing. 
 
When configured, three beeps can also indicate a communications timeout 
during normal scanning mode. 
 
When using single-code-configuring, the scanner will beep three times: 
a normal tone followed by a short pause, a high tone and then a low tone.   
This indicates that the single configuration bar code has successfully 
configured the scanner.
