How to switch from hand controller to chin controller

[luckywife]

We have a permobil c300. My husbands hand is too weak to control the joystick. We have a chin boom on the chair, but I cant figure out how to switch from the joystick to the chin control. Any help would be appreciated.

Have you tried the Permobil web site. They should at least have a number to call.
