m-e BELL-510 RX Wireless Doorbell


Thank you for purchasing this radio doorbell from the Bell series.
Please read the operating instructions carefully and keep them for future use.
This radio doorbell can be used on the move thanks to its built-in rechargeable battery. The battery is charged via the integrated charger with the linchpin.
If a tuned-in radio doorbell transmitter is actuated, the radio doorbell plays a ring tone and/or signals the ringing visually, depending on the setting.
In addition, the radio doorbell is equipped with a repeater module and can forward received radio signals to more distant receivers of the Bell series.
Depending on the transmitter model, the range is between 100 and 500 meters under optimal conditions. The range is influenced by various factors, e.g. metal or UPVC door frames, walls or other devices operating on the same frequency.
All transmitters in the Bell series are compatible with this radio doorbell.

Press the lynch pin lock down to unfold the lynch pin and plug the radio doorbell into a mains socket. The charging process begins and the control LED flashes green. The radio doorbell does not have to be switched on for this. If the control LED lights up green continuously, the charging process is complete.
To be able to use the receiver on the move, push the linchpin back until it snaps back into place under the linchpin lock.


Use the function selector switch to choose whether the radio doorbell only plays the ring tone or only the light panel flashes or both together. Slide the switch to the desired position.

  • Button Icon Only flashing light panel

The control LED indicates various states.
If the radio doorbell is plugged into a 230V mains socket, the control LED flashes green to indicate the charging process.
If the LED lights up green continuously while the radio doorbell is plugged into a mains socket, the battery is fully charged.
If the LED flashes red, the battery is almost empty and the radio doorbell must be recharged.
If the LED flashes blue, the radio doorbell is in learning mode.


If no transmitter has been taught-in to the radio doorbell yet, the radio doorbell is in teach-in mode immediately after it is switched on; the control LED indicates this by flashing blue. Now trigger the desired Bell transmitter to learn it. The radio doorbell plays a ring tone and automatically leaves the learning mode.
To teach in another transmitter, press and hold the learning code button for approx. 3 seconds. The control LED flashes blue when the learning mode is activated. Then trigger the Bell transmitter to which the radio doorbell is to addition ally respond. The radio doorbell plays a ring tone and automatically leaves the learning mode.
This procedure must be repeated for each additional transmitter. A maximum of 4 transmitters can be taught in.


The volume can be adjusted in several steps via the two keys Plus (4) and Minus (5). Briefly press the Plus key to increase the volume one level or the Minus key to decrease the volume one level.


The color of the light panel is set with the color selection key (6). A total of 7 different colure  are available. Each press of the key changes to the next color. The last color played back is automatically saved.


The radio doorbell has an integrated repeater function, i.e. it can forward radio signals from several transmitters of the Bell series and thus increase the range of the transmitters.
It is not necessary for the Bell transmitter to be tuned in to the radio doorbell in order to be forwarded. The repeater function is always active and cannot be switched off.
Bell transmitters that are tuned in to the radio doorbell are also forwarded. The radio doorbell itself, however, only rings for transmission signals that have also been tuned in to the radio doorbell.
This makes it possible, for example, for the radio doorbell in a two-family house to ring only when the bell button for family 1 is pressed. The radio signal of the bell button for family 2 is only forwarded without the radio doorbell itself ringing

Note Icon Note: There is a time delay of approx. 3 seconds between the reception of the signal until it is forwarded. The control LED indicates a forwarding by briefly lighting up.


To reset the radio doorbell to factory settings, press and hold the learning code button for 3 seconds until the control LED flashes blue. Release the button and hold it down again until the control LED stops flashing. After this, the radio doorbell is back in the delivery state and no more transmitters have been learned.
Then switch the radio doorbell off and on again. The control LED flashes blue and the radio doorbell is in learning mode. Now all the desired transmitters can be taught in again. Please refer to the section “Programming transmitters”.
