[Standard] Standard mobile dualbnd 5718 and control head

[Martyp]

Hello all,
  I own a Standard dual bander model C-5718
with the CMP control head. I am visually impaired and have installed the
tranciever into my wife's car. My problem is how to get it to go from the
outboard speaker mode to the one on the handhelp control head. If anyone
can help my wife do this, I would appreciate it...when we moved, we lost
the manual. Thanks in advance. I believe it was their last dual bander with
800-900+ mhz capabilities without modifiying it.

Kind regards,
Martin Jay Pearlman, W3QK
