Certain products such as portable phones, broadcast to the base unit of the phone to the same frequency as the monitor. This results in signals being picked up by the nursery monitor. In addition, many external conditions can affect the range on the monitor, including electrical equipment, power lines, concrete, steel studs in walls, burglar alarms, televisions and computers. To make them even more convenient for parents, today s monitors have a variety of features. Portability Portability provides parents mobility and freedom with a parent unit that operates from the base or batteries, and most provide a belt clip for attachment to clothing.
Some models have the same option on the baby s unit as well.
Channel Selection One of the most important features on a unit is channel selection because it helps eliminate interference. Most monitors have two preset channels, which is similar to having two preset channels on your car radio. If parents experience interference from within the home or from a neighbor, the unit can be changed to an alternative channel. If there is interference on both channels, move the monitor to a different area of the room. Sound Display Lights Lights allow parents to see, as well as hear, if baby is making noise, in a loud environment or if the parents are watching TV and don t want to hear static sounds from the monitor.
