Alert Info for Uniden EXP1240

So I just purchased the Uniden EXP1240 that FreePBX showcased at Asterisk World.

The owner’s manual is listed below, but I can’t find anything about distinctive ringing. Does anyone know what would be put in the FreePBX Alert Info field to enable a distinctive ring? Thanks.
