When the device scans the pairing bar code it issues various beep sequences indicating successful or 
unsuccessful operations. See 

 for beep sequences that occur during pairing operations.

Short low-high beeps

Device has paired with the cradle.

Short high-low beeps

Device has unpaired with the cradle.

Note: When connected to a remote device using SPP or HID, if a 
disconnect beep sequence sounds immediately after scanning a bar 
code, check the host device to determine if it received the transmitted 
data. The device may have transmitted the last bar code scanned after 
losing the connection.

Long low-long high beeps

Unsuccessful pairing attempt. See 

Long low-long high-long low-long high beeps

Remote device rejected connection attempt, possibly due to an attempt 
to pair with a cradle that is already paired with the maximum number of 
devices.

Four long low beeps

1.

A transmission error was detected in a scanned symbol. The data is 

ignored. This occurs if a unit is not properly configured. Check option 
setting.

2.

When communicating with a cradle, the cradle acknowledges 

receipt of data. If the acknowledgment is not received, this transmission 
error beep sequence sounds. Data may still have been received by the 
host. Check the host system for receipt of transmitted data. If data was 
not received by the host, re-scan the bar code.

Five high beeps

Emitted every 5 seconds while a reconnect attempt is in progress. See 

.
