Motorola SD4500 advanced digital cordless phone system
As more consumers now use their mobile number as their primary contact, there's a growing market for products that integrate a cell phone and a cordless landline phone into one system. The Motorola SD4500 advanced digital cordless phone system is one such solution as it allows you to make calls on your cell phone's network using a standard cordless phone. Expandable and customizable, the SD4500 system includes the Motorola SD4505 cell phone dock ($99.99) and a choice of up to six Motorola cordless phones with varying features. We used the Motorola SD4581 ($89.99) for our tests, but you also can choose the Motorola SD4502 cordless phone, which plays video from the accompanying Motorola SD4504 wireless camera. Though all pieces are sold separately, the system may be worth the expense if--and only if--you already own a Motorola cell phone. It's a convenient arrangement not only because most cell phones are uncomfortable to hold for long periods of time, but you can also place the cell phone dock at a spot with the best reception, thus guaranteeing crystal-clear sound no matter where you are in the house.
The core product in the Motorola SD4500 system is the SD4505 cell phone dock station. Styled in basic silver, it's relatively compact (3.4 by 4.0 by 1.5) and lightweight (0.3 ounce), so you can fit it almost anywhere in your house. On the outside, its only feature is a small LED that glows when your cell phone is connected. Only Motorola phones are compatible with the dock (check with Motorola for the full list of models), so if you have a mobile from another manufacturer, you should check out theinstead. We plugged in our and found that the dock also charges the phone. The V330 fit securely in the docking station, and we had no problem making the connection.
As stated previously, we tested the docking station with the Motorola SD4581 cordless phone, which includes a 2.4GHz cordless phone, a charging base, and an answering machine. Like the RCA Cell Phone Docking System, the SD4581 can support both landline and cell phone calls, but you don't need a landline to connect it to your cell phone. The base looks fairly complicated, with a total of 13 buttons on its surface, all of which were tactile and easy to use. Just under the handset charging dock is a Page button, which is used to page the handset, as well as register accessories such as the cell phone dock (see below). On the left of the Page button is a charge-indicator light, and on the right is an indicator light that remains lit when the handset is in use and blinks when there's new voicemail if you're signed up with such a service from a landline phone provider--though having an answering machine makes voicemail seem superfluous. Next to the dock on the right is a circular LED that displays the number of answering-machine messages. Underneath are four answering machine buttons in a diamond shape--play/stop, skip backward, skip forward, and delete--while below them are three pill-shaped buttons that turn the phone on and off, record announcements, and record memos/forward messages. At the bottom right, there are three more circular buttons that are used to set the date and time. The most prominent feature of the phone base, however, is the large speakerphone grille on the bottom left that's appended with two volume buttons.
