Updating a firmware
While each of these platforms are currently using versions in the 5.4.x branch the actual release versions may or may not have the exact same build number between the different platforms.Note that it is possible to load the wrong firmware on a device in the event that the software packages are somehow mixed up between these various products.
As previously covered in this article a centralized provisioning server can be deployed, or an existing deployment designed for other Polycom SIP phones can be leveraged by the Trio.(Note that while the some VVX desktop phone models do include a standard USB port they do not currently support this USB upgrade method.) While most any USB flash drive should work for this process it is recommended to use a USB 2.0 drive.And because the firmware is only a few hundred megabytes then pretty much any available USB drive can be used.You can update the TS-480HX/SAT firmware by connecting the TS-480HX/SAT to the PC by using an RS-232C cable.When the KENWOOD HF/6m linear amplifier TL-933 (only for Japanese market) is connected and the TL-933's [TUNE] button is pressed and the TL-933's automatic antenna tuning is completed, receiving audio from the TS-480HX/SAT is muted on rare occasions.
