Motorola SD4505 is a wireless cell phone dock module that allows you to access your cell phone's features through your cordless phone. With SD4505, you can make and receive calls, access your cell phone's contacts, and even use your cell phone's data services (if available) - all without having to take your cell phone out of the dock.

To get started, simply plug the SD4505 into a power outlet and insert your cell phone into the dock. Once your cell phone is docked, the SD4505 will automatically register with your cell phone and begin syncing your contacts.

To make a call using the SD4505, simply press the "Connect To" button on your cordless phone and select "Cell Dock B." Then, dial the number you want to call and press the "Talk" button. To answer a call, simply press the "Talk" button on your cordless phone.
