Congratulations on purchasing your doorbell transmitter acoustic.
We hope it will give you many years of reassuring operation. Please read
through these operating instructions carefully. They tell you how to set up
the system correctly and explain all the system’s features to you.
Standard components
Please check if all following components are included:
- lisa radio doorbell transmitter acoustic
- microphone cable 1 m
- stylus for setting the signal type
- 9 V block battery
- operating Instructions
- warranty card
If any parts are missing, please immediately contact your dealer or the manufacturer directly.
Operating principle
A signaling system consists of at least one transmitter and one receiver. The
radio doorbell transmitter acoustic uses a microphone to pick up the signals
from doorbell. It converts these signals into radio pulses (868.35 MHz) and
transmits them to the receiver without the need for wi-res.
Special features
When a signal is detected, it is transmitted for a total of 22 seconds. This increases both the reliability and the range of the system.
Setting up the system
Inserting the battery
There is a battery compartment on the back of the radio doorbell
transmitter acoustic. Open it by sliding the cover of the battery compartment
to the right of the receiver using your thumb. Connect a 9 V block battery to
the connector plug, insert the battery into the battery compartment and close
the device. When the battery is connected, the receiving signals may be
triggered once.
Setting the correct radio channel
A special digital transmission process 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 radio doorbell transmitters acoustic 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.
Installing the microphone cable
Use the adhesive ring to glue the microphone to the sound outlet of your
doorbell/intercom system and plug the microphone cable into the connection
jack on the bottom of the radio doorbell transmitter acoustic.
To do this, pull off the backing foil from the adhesive ring on the
microphone.
For optimum function of the transmitter, its sensitivity dial switch must be
set so the transmitter reliably responds to the doorbell.
Fig.: Plug in the microphone cable and stick the microphone over the acoustic output cover of your door-bell.
Setting the sensitivity
Set the sensitivity controller to its lowest level (turn to the anticlockwise
stop). Activate the doorbell and gradually increase the sensitivity of the
transmitter (by turning the dial clockwise) until the transmitter reacts to
the doorbell.
If your intercom system operates with different signal tones, make sure that
both signal tones are reliably detected.
Setting the type of signal
You can select one of the two signal types on the right-hand side of the radio
doorbell transmitter acoustic. Use the stylus that comes included with the
device to push the signal selection switch to the desired setting.
Doorbell 1
To indicate a signal from Doorbell 1, set the signal selection switch to the
top position. This will send the Doorbell 1 signal to all the receivers that
are switched on and set to the same channel.
Doorbell 2
To send a signal for Doorbell 2 to all the receivers which are switched on,
set the signal selection switch to the bottom position.
Call button
Pressing the call button on the radio doorbell transmitter acoustic causes a
signal to be triggered on every receiver, which is set to the same radio
channel as the transmitter. The call button lamp lights up to indicate this.
This makes it possible to call people who are in different rooms. Also, this
button can be used for checking the system of its functioning even when the
microphone cable is not connected.
Mains operation
You can also operate your radio door-bell transmitter acoustic via the plug-in
power supply unit (A-2992-0). To connect the PSU, insert 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 building 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 sur- faces, which reflect radio waves, for example floors and walls. This may lead to the signal wave being weakened or even cancelled out by the reflected wave.
- Metallic objects reduce the range due to the shielding effect of the metal.
- Particularly in towns and cities, the- re 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 transmitter, in
order to achieve the greatest possible range from the radio transmitter:
- 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 re- stricted by metallic shielding.
Maintenance and care
The radio doorbell transmitter acou-stic does not require any mainte-nance. 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 radio doorbell trans-mitter acoustic where it will be expo- sed 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.

invoice/ till receipt.
Always specify the product number in any event.
Battery life
Under normal conditions (7 transmis-sions a day), the transmitter battery
should last for about 1 year. Press the pager button on the transmitter to
test the battery charge status. If the „Send“ signal LED on the transmitter
does not come on, the battery needs to be replaced!
