Error
Message
Description Corrective Action
Error06
NVRAM parameters have been lost. The MPRX
will not function properly because the RF
section is shut off 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 8-14 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.
ErrorRF1
Warning message that the RF board did 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.
