C100 Signalling Tone Remote Help

[Flatbush97]

All,
I recently picked up a C100 remote with MDC signaling capabilities. The remote works well with no issues. I was wondering if anyone knew of a key combination that would allow me to change the screen contrast as it seems very light. I assume that this can be adjusted.

I have a "page" button that seems to send a quick call group. Is there any way to see what group it is sending? Any way to change it? Can the group be entered on the keypad?

Additionally, if anyone knows how to input MDC values that are not 0-9 (ie a-d) using the keypad. I assume that as is usually the case, the F = wildcard and the E as first charachter = group.

If someone has a user manual in available I would greatly appreciate. I currently have the standard C100 tone remote, which does not have any additional information

From what I have seen to date, the C100 is not RSS customizable. If someone knows otherwise please let me know.
Thanks in advance
Aaron
