Appendix B: Minimum Software
Requirements for Rev C Handsets
Recent hardware changes affect the Spectralink 80-Series Handsets. The affected products can
be identified by a “Rev C” on the label.
The changes require the minimal software version
122.024
to run on the handset.
The default software installed at the factory will not allow older versions of code to be
downloaded to these handsets, either over the air or via the Handset Administration Tool
(HAT).
If a site is set up to download older code over the air (from a TFTP server), Rev C handsets will
silently fail to download the code, will boot to the functional code currently installed and will
display a download icon with a strikeout (X) through it to indicate the download failed due to
incompatible software. For more information on the failed download icon, please refer to the
Status Icons
section in Chapter 1 of the
Spectralink 80-Series Handset User Guide with
Spectralink Radio Protocol (SRP)
.
If a system administrator attempts to download down-rev code to the phone using the HAT tool,
HAT will display an error and fail to download the code.
Note that due to this behavior, it is possible that a site may be running older code on pre- Rev C
handsets and newer code on Rev C handsets. This is an acceptable configuration, but users
should be aware that there may be slight changes in behavior with different versions of
software.
