SCANNER OPERATION 
Indicators 
Audible  
When the scanner is in operation, it provides audible feedback.  These sounds 
indicate the status of the scanner.  Eight settings are available for the tone of the 
beeper (normal, 6 alternate tones and no tone).  To change the tones, refer to 
the MetroSelect Single-Line Configuration Guide (MLPN 00-02544x) or 
MetroSet2’s help files. 
One Beep  
The scanner will beep once after communication has been 
established and the unit is properly placed into the cradle.  
When the scanner successfully reads a bar code, the scanner’s white 
LED will flash and the unit will beep once.  
When the CodeGate button is pressed for 3 seconds, the scanner will 
indicate it has entered full sleep mode with a extended beep.  
Two Beeps  
When the scanner has a low battery voltage, it will emit two beeps 
after a successful scan and flash the amber LED every 5 seconds. 
When there is a Flash ROM upgrade needed, the scanner will beep 
twice followed by alternating flashing of the blue and white LEDs. 
When communication has been broken between the scanner and 
cradle, the scanner will emit two combined high and low tones while 
the blue LED flashes. 
Three Beeps  
When entering configuration mode, the white LED will flash while the 
scanner simultaneously beeps three times.  
When exiting configuration mode, the scanner will beep three times 
and the white LED will stop flashing. 
When using single-code-Configuration, the scanner will sound a  
3-combination tone (a short pause followed by a high tone and a low 
tone).  This indicates a single configuration bar code has successfully 
configured the scanner. 
When scanning a Bluetooth address bar code, the scanner will beep 
three times. The scanner’s blue LED will start to flash as it attempts to 
establish a communication link. The scanner will emit a 3-combination 
tone and the blue LED will stop flashing, staying steadily illuminated 
to indicate communication between the scanner and the cradle has 
been successfully established.  
Razzberry Tones 
This tone indicates a type of failure.  Refer to “Failure Modes" on 
page 25.
