Technical characteristics of the radio nurse
Before purchase of the radio nurse pay attention to her main technical characteristics. Devices can be digital and analog. They differ with communication quality and, respectively, the price. Analog radio nurses often work with hindrances, it is better to use them on open space. With higher quality - digital devices, they are protected from hindrances and have many settings. Various models of radio nurses have several power supplies. It is better to buy the device working both from the power supply network, and from accumulators (or batteries).
At vyby radio nurses it is necessary to consider that the range of signal transmission decreases in the closed space.
In some models of the radio nurse (baby minder, i-niania, maman wt, care, chicco, brevi) between the transmitter and the receiver only the unilateral communication when parents hear the child who is in the nursery exists. In other models (the two-way communication is philips, tomy, chicco, brevi, motorola), in this case parents can communicate with the child.
The average distance of signal transmission variously can also make up to 400 meters. Models with action to 100-150 m can be chosen for use in the small private house. For the city apartment there is enough radio nurse with signal transmission distance to 50 meters. In a travel or to a trip to giving it is better to buy the device with range to 400 m. If the transmitter and the receiver strongly moved away from each other, the radio nurse will give a special signal.
Main operating modes, additional functions of the radio nurse
The radio nurse has several modes of observation: sound, light and vibromode. The main mode – sound, at the light mode in case of fixation by the sound transmitter the receiver gives a signal by means of indicators. It is convenient to use the vibromode on the street: the device can be hung up on a hand or to put in a pocket. Some models of radio nurses have useful additional functions, for example, a children's night lamp. It joins automatically when the child gives a vote, and is disconnected in the absence of a sound within several minutes.
