People Finder LT

[pfdunit138]

Hello...

My fire department uses a Motorola People Finder LT for two-tone encoding. We have a list of the 2-digit numbers to enter to page our department, but we would like to add additional tone frequencies for different paging purposes (officers, engineers, etc.) but don't know how to determine what numbers sound what frequency. (i.e. when we enter "98", we get a two-tone transmission of 1985.0 Hz and 1530.0 Hz. We have the instruction manual for the unit, but it provides very little information.

Is there a way to determine (or change) what the numbers do? I've come to find that information on this tone encoder, even on this board, is scarce at best Hopefully somebody can help!

From your tones you listed, you are using Plectron tones. I don't know how the numbering scheme goes with Plectron on PeopleFinders.

My best suggestion would be to get someone with a service monitor and read the tones directly.

Later versions of PF's were programmable but the early versions required a PROM, good luck on getting one of those.

For the People Finder LT and Plus, the tones and capcodes are determined by how it was previously programmed. They have their own RSS and you can set up the tone programming accordingly.

They were also programmable from the front keypad, but I'm not sure if you can define paging tones that way.
