Firmware versions and this manual
TE's guide describes OS 1.1.15, while this manual targets OS 1.1.33; facts that changed later carry the release that changed them. How to see which OS your unit runs.
OS 1.1.17 to 1.1.33 added features and fixes that TE's guide does not mention yet. When an answer depends on the version, check the boot screen first; this manual assumes 1.1.33.
