Because the program files match, there are 2 menu screens and 10 function
keys. The greater than sign (
> ), in the lower right corner of the display,
indicates that a second function key menu is available.
The following functions are available to you:
Function Key Description
[ F1 ], OFFLINE Returns you to the utility menu display.
[ F2 ], UPLOAD
Reads the program from the processor RAM and
copies it to the HHT RAM. This function
overwrites any program currently stored in HHT
RAM.
[ F3 ], DOWNLOAD

processor RAM. This function overwrites the
program stored in the processor RAM.
[ F4 ], MODE

mode to Run, Test, or Program.
[ F5 ], CLR_PRC

Exceptions
The function keys and menus vary depending on how the HHT and processor
programs relate. In the following example, assume that the HHT has
previously been attached to this processor, but the offline program in the
HHT has been altered and no longer matches the program in processor RAM.
If the HHT and processor programs do not match, the following display
appears when you press
[F1] , ONLINE:
