[Wi$e]

Прошивка процессора MP20 для OfficeServ 7200, версия 4.53a.

1. The database of OS7000 series software package V4.53 is not compatible with that of any earler package version than V4.52. (The database of V4.53 is only compatible with that of V4.52)
Therefore, you have to download the database from the system before upgrading main software package to V4.53 and then upload it after upgrading the software to V4.53.
2. OS7400 MP40 and OS7200 MP20 V4.53 packages cannot be directly upgraded from any earlier version of package (V4.1x, V4.2x, V4.3x and V4.4x) using Installation Tool. It is only possbile through V4.51 because of the size of main software package, that is, you have to upgrade twice (V4.1x~V4.4x -> V4.51 -> V4.53) when you upgrade it by IT.
However, you can drectly upgrade the main software to V4.53 when you upgrade the software by copying the main software package to SD card using PC.
The other systems such as OS7030, 7100 MP10a/MP11 and OS7200 MP20 are free from this limitation although you try to upgrade to software package using IT.
