|Radio Shack Wireless Mail Guard, Audio & Visual Alert|
Using your RadioShack Mail Guard is a convenient way to monitor your mail box without walking outside to check for yourself. When the photo sensor senses a change in light (when the mailbox is opened), the system's base (receiver) beeps and its indicator lights. You can set the transmitter to the desired sensitivity setting for the appropriate lighting environment, Hi for darker mailbox interiors, or LOW for interiors which may leak light inside. The system can transmit up to about 150 ft, clear line-of-sight on one of three channels (A, B, or C) so you can have the best transmission with little or no interference from nearby sources.
