Table 9-1 Error Messages
Error
Message
Description Corrective Action
Error06
NVRAM parameters have been lost. The
Encompass 4 Reader 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 Encompass 4 Reader attempts to
reset the PLL.
Reset the RF frequency. Refer to “Radio
Frequency” on page 8-15 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.
Error11
The operator is attempting to use an
Intellitag-based tag in Wiegand mode while
the Encompass 4 Reader is in ID-only
mode, thus Wiegand compatibility issues.
Enable eATA mode using command #489
if Wiegand operation is needed and the
tags are programmed with Wiegand data.
