Error Messages
The MPRX transmits an error message if a command received from the host is not a recognized command
or if information supplied with the command is incorrect. The reader sends this message to diagnostic
commands if the reader fails the specified test.
Table 28 contains a list of error messages.
Table 28 Error Messages
Error
Message
Description Corrective Action
Error06 NVRAM parameters have been lost.
The MPRX will not function properly
because the RF section is shut o until the
frequency is reset.
Reset the frequency using Command
#647XXX.
Error07 The RF phase locked loop (PLL) has
lost lock and is unable to operate at its
intended frequency. RF output is disabled
while the MPRX attempts to reset the PLL.
Reset the RF frequency. Refer to “Radio
Frequency” on page 6–93 for instructions.
Error08 The RF PLL has successfully regained lock
and has been reset to its proper operating
frequency. The RF section is returned
to its state prior to losing lock (enabled/
disabled). #Error08 will only be issued
after #Error07 has been issued.
No action necessary; the previous error has
been corrected.

not return an update acknowledge signal
If the reader indicates a single #ErrorRF1
event and recovers from the error, no
corrective action is required. You may want
to track this error message if it should occur
again. If the reader indicates repeated
#ErrorRF1 warning messages then return
the reader to the factory.
ErrorRF2 Warning message that the RF module did
not return an INIT DONE signal
If the reader indicates a single #ErrorRF2
event and recovers from the error, no
corrective action is required. You may want
to track this error message if it should occur
