Communication Errors
A communication error occurs when the scanner, cradle or host fails to properly
communicate. When a communication error occurs using the default application, the
scanner emits 4 beeps (LO HI LO HI) and displays a "Failed Communication" error
message, like the one shown below. The three-digit error code on the scanner screen
indicates what type of communication problem occurred. Error code 015 generally
indicates the scanner is out of RF range, not properly paired to the base, or the base may
have lost power. For a detailed list of all the error codes see Appendix D, Messages and
Error Codes and Beeper Indications / Default Application Error Codes on page 4-7.
To return to the application, press <ENTER>.
Three types of communication errors can occur:
1. The RF transmitted data was NOT received by the cradle.
2. The cradle received the RF transmitted data, but the scanner did NOT receive a
cradle's acknowledgment.
3. The host and cradle are not communicating properly.
RF Communication Errors
1. If the RF transmitted data was NOT received by the cradle, move the scanner
closer to the cradle to reestablish communication, then re-scan the bar code. If the
communication has been reestablished, the scanner will sound a good decode
beep and no error beeps. Resume normal scanning.
2. If the cradle received the RF transmitted data, but the scanner did NOT receive a
cradle's acknowledgment, move the scanner closer to the cradle to reestablish
communication, then re-scan the bar code. If the communication has been
reestablished, the scanner will sound a good decode beep and no error beeps. In
this scenario data may have been transmitted to the host. If the cradle had
previously sent data to the host, it will NOT pass this re-scanned data to the host.
Resume normal scanning.
