INSTALL INSTRUCTIONS:
=====================
Load “alp.bin” and “twebsite.bin” from the zip file into the root directory (not in a folder) of a FAT32 formatted USB drive.
With the T-series unit switched on, insert the USB drive into the “CONFIG / FIRMWARE UPDATE” socket on the front panel.
Power cycle the T-series unit, or Restart from the Network tab of the web interface.
The unit will restart – DO NOT TURN OFF THE POWER. The status LED will flash amber, then the unit will start as normal. This should take only a few seconds. The LED will continue to flash amber while the revised website is loaded. All previous user settings will be maintained and applied.
Remove the USB stick from front panel.
