Thanks for your reply, but I am still not clear.

>> You can check what version software that you have by going to:
>> HELP -> ABOUT

This gives the current version, not the next update version.

>> If you click on the help (?) it will give you information about update.

I think this just gives general info on updating - not the version numbers.

>> to install go to
>> MAINTENANCE -> software update -> Function: System software update.
>> Browse for the update
>> Upload the update

Under MAINTENANCE -> software update there is no Function: System software update
Here is a copy of what I see

1. Apply update
Update complete.
Press reboot to start from new system.

2. Reboot from new system
Copy current settings
reboot

Run previous system
Press reboot to run form previous system

I think that an update has already been uploaded & so the Function: System software update
is not present. My problem is that if I press "Press reboot to start from new system" there
is no information as to which new system I will update to. It is possible I suppose that I uploaded an update a while ago while testing the system.
