Firmware
Each unit is shipped with the latest firmware version installed. As newer firmware becomes available it can be
downloaded from the Zaxcom website:
http://www.zaxcom.com/firmware-updates
Newer version of beta firmware may be found on the Zaxcom Forums:
It is recommended to keep a copy of the “SNXXXX.ME” file for each transmitter. The SNXXXX.ME file contains the
setup parameters of that specific transmitter - so in the event that there is a problem with the transmitter and the
settings get corrupt the SNXXXX.ME file can be used to recreate the setting for that transmitter. To copy and save
the SNXXXX.ME files simply format a card in each transmitter then copy and archive the SNXXXX.ME files to a
computer.
