You only need to setup your Read With Me™ controller one time per DVD player. Your Read With Me™ controller can setup to be played with up to 3 different DVD players. There is a 3-position memory switch on the underside of your Read With Me™ controller. Each position of the switch can be programmed to a different DVD player. Refer to your Read With Me™ User’s Manual for instructions on how to use the 3-position memory switch.
