3M does have a 2 channel programmable instrument with up to 8 programs in
the MultiPro version (BTE, canal, or ITE) or 1 program in the SinglePro
version (BTE,canal, or ITE). The instruments are programed using a
model80 interface box a battery bill and a PC. It is a very good system
and does not need a remote control. The programs are changed on the
MultiPro by pushing a button.
