If you have another analogue or digital STB and you wish to use the same RF Signal then
you can connect it via the loop through. Connect one end of a RF cable to the TV/VCR on
the STB and connect the other end to the RF(ANT) on your second STB.
HUMAX digital set-top box is a highly sophisticated product - incorporating one of the best
software applications.
Whenever a problem is found with this software or, in fact, extra functions or enhanced
applications are added, the software in the equipment has to be upgraded.
In order to maintain proper performance of the product, it is essential to have the most
up to date software. The latest news and release of software versions may be found at
HUMAX website - http://www.humaxdigital.com.
It is recommended that users register to HCSA (HUMAX Customer Service Area) and
periodically check for the availability of software upgrade.
There are three methods to upgrade the software :
(a) set-top box to set-top box download (copies the software of the main unit into slave unit);
(b) pc to set-top box download (downloads the software directly from pc to the model
requiring upgrade);
(c) OTA over-the-air (downloads the software where the manufacturer reserves the right to
decide when and where to release over the air).
Over The Air (OTA) is simply another alternative for downloading software versions.
However, the manufacturer reserves the right to decide when and where this software
upgrade can take place by "beaming" latest software versions over the air.
SUSS (TM) is an official trademark and logo for HUMAX loader software to perform OTA.
The software upgrade will only occur under the following circumstances:
1) the equipment should have appropriate loader software;
2) the manufacturer decides to release software downloading;
3) the equipment must be "tuned" properly to the OTA channel that the manufacturer uses.
