The 3910 is auto paired to the base unit. The serial number on the phone must match the serial number on the base unit for it to synch. There is no on/off button for the phone. If it has a charged battery, it should power up once the battery is inserted. If it is not, you have a bad phone.

The 3920 could be synched to other base units. The 3910 cannot. check your serial numbers to make sure they match.
