6.3 Automatic Firmware Upgrade Procedure

With automatic firmware upgrade function enabled by default, the Gateway automatically
checks if a new version firmware file is uploaded on the dedicated server on an
applicable external network and, when a new version firmware file is found, upgrades the
firmware as scheduled. For the purpose of this automatic firmware upgrade, a new
version firmware file is downloaded in the Gateway upon finding on the server or, if the
connection is busy, at the time of upgrading the firmware.
The said checking for a new version firmware file is performed once within 24 hours of
initial startup of the Gateway and once per day thereafter.
