Components not included

External microphone.

Functional principle

A signalling system consists of at least one transmitter and one recei-ver. The RF baby cry transmitter records the sounds a baby makes via a microphone. It converts these signals into radio pulses (868.35 MHz) and transmits them to the receiver without the need of wires.

Special features

When a signal is detected, it is transmitted for a total of 22 seconds. his increases both the reliability and the range of the system.

Inserting the battery

There is a battery compartment on the back of the RF baby cry transmitter. Open it by your thumb, with sliding the cover of the battery compartment to the right of the receiver. Connect a 9 V block battery to the connector plug, place the battery into the recess and close the receiver again. When the battery is connected, the receiving signals may be triggered once.

Setting the correct radio channel

A special digital transmission pro-cess ensures that the radio signals are picked up without errors. This process also makes it possible to set 10 different radio channels. When supplied from the factory, all RF baby cry transmitters are set to channel 0. It is only necessary to set units to other channels if you have several different users operating units in the same building. Set the required channel by using a small screwdriver to turn the channel selector switch, which is located towards the top of the battery compartment, to the required channel number. All transmitters and receivers must be set to the same channel.

Setting the microphone

The RF baby cry transmitter has a built-in microphone which reacts to the sounds made by your child. The dial switch for setting the sensitivity of the microphone is located on the underside of the unit. Set the sensiti-vity so the RF baby cry transmitter reliably reacts to the sounds made by your child. Dial switch is set to the anticlockwise stop: Low microphone sensitivity. Dial switch is set to the clockwise stop: High microphone sensitivity.

Positioning the unit

Switch on the unit and position it close to your child. It is possible that the transmit signal may be triggered once when you switch on the unit.

External microphone

(A-2971-0): Simply plug the microphone cable into the socket on the underside of the RF baby cry transmitter. The microphone can now be placed very near to the baby if the built-in microphone is too far from the baby to pick up the sound adequately.
Warning : The additional microphone and lead could prove a danger to a baby or small child. Ensure that they are well out of reach.

Person call button
Pressing the person call button on the RF baby cry transmitter causes a signal to be triggered on every receiver which is set to the same radio channel as the transmitter. This makes it possible to call people who are in different rooms. Also, this button can be used for checking the system is functioning.
Mains operation
You can also operate your RF baby cry transmitter via the plug-in power supply unit. To connect the PSU, ins-ert the connector on the end of the PSU cable into the corresponding socket on the left-hand side of the device. Then plug the power supply unit into the normal 230 V socket in your house.

Radio range
The radio signals are designed to have a range of 80 meters under optimum conditions. The following conditions may result in a reduced range:

•  Signal transmission through buil-ding structures or vegetation.
•  Interference from TVs, computer monitors and mobile phones. Under certain circumstances, this may prevent the receiver from func-tioning at all.
•  Positioning of the transmitter at an unfavourable distance from surfa-ces which reflect radio waves, for example floors and walls. This may lead to the signal wave being weakened or even cancel-led out by the reflected wave.
•  Metallic objects reduce the range due to the shielding effect of the metal.
•  Particularly in towns and cities, there may be many other sources of radio waves which can disrupt the original signal.
•  Having units operating at similar frequencies located close to one another may also result in mutual interference.

Positioning the radio transmitter

Bear in mind the following points when positioning the radio transmit-ter, in order to achieve the greatest possible range from the radio trans-mitter:

•  The radio transmitter should not be set up close to devices which emit powerful interference signals, such as TVs, computer monitors or mobi-le phones.
•  The radio transmitter should not be placed on metallic objects, since otherwise the radio range will be restricted by metallic shielding.
•  Position the radio transmitter as close to the centre of the building as possible, at a medium height in the room.

Maintenance and care

The RF baby cry transmitter does not require any maintenance. If the unit does become dirty, simply wipe it clean with a soft, damp cloth. Never use spirits, thinners or other organic solvents.
Do not set up the RF baby cry trans-mitter where it will be exposed to full sunlight for long periods. In addition, it must be protected against excessive heat, moisture and severe mechanical shocks.
Note: This product is not protected against splash water. Do not place any containers filled with water, such as flower vases, or anything with an open flame, such as a lit candle, on or near the product.
Please make sure that the batteries are not exposed to excessive heat from such as sunlight, fire or anything similar.
