To install a new firmware version on a base station and/or handset, please follow the instructions provided in the firmware update guide.

Please read the release notes carefully before upgrading.

WARNING - Please be sure to read this Information!

M5 repeaters are not supported in this firmware version and will not be usable after the upgrade!

New M6 repeater is coming March of 2023.

Downgrade to 530B7 is possible on M900, but will remove "User" and "Engineer" profiles. 

After upgrading from <=530B7, the base asks to set new passwords for "Engineer" and "User". Make sure you either provision the passwords or you change them immediately !!!

Please reboot the base station(s) (chain reboot in multi cells) before triggering the upgrade, to free up some memory and avoid any issues.

This version has two additional user profiles introduced after 530B7. ("User" & "Engineer")

  • The base will ask for new passwords for these profiles after the upgrade. To avoid entering new passwords by hand you shall provision your default passwords of your choice instead. 

    Users and Passwords in the configuration to change:

    <!-- <http_pass>**********</http_pass> -->
    <!-- <http_basic_pass>**********</http_basic_pass> -->
    <!-- <http_engineer_pass>**********</http_engineer_pass> -->
