Yaesu MH-36D8 DTMF Microphone Question
 

Greetings...just picked up the MH-36D8 hand microphone for use on my
FT847. There are two buttons on the mic, labeled A and B. The little
paper that came with the mic states that these buttons are used to
"Activate an accessory function" When I push either of them they both
change the tuning rate on the FT-847 to FAST. I "think" that I should
be able to assign a function to either of these keys, but can't find
any mention of it in the FT-847 manual or on the little scrap of paper
that came with the mic...Any ideas? Thanks....
