How to use Bellman Audio Domino The BE2210 and BE2230 Bellman Audio Domino Personal Hearing Systems are personal hearing systems which have been specifically developed to provide an excellent sound experience even in demanding situations. Bellman Audio Domino works extremely well for speech and music. You can use the built-in microphones in the Receiver Unit and the Transmitter Unit or use an external sound source.
Symbols and indicators The following symbols are used in the user manual and can be explained as follows: The warning triangle indicates information which must be followed in order to guarantee operation and also in some cases to ensure personal safety. The light bulb (tip, note) indicates information which can be useful to help you get the most out of the product. 5s I II V 58 III IV I A permanently lit LED is indicated by a solid indicator.
Charging Both the Transmitter and Receiver Units are supplied with built-in rechargeable batteries. The batteries in both the Transmitter and Receiver Units must be charged before using the products for the first time. Bellman Audio Domino contains Lithium-Ion batteries and a universal charger with plugs for the EU, United Kingdom, USA and Australia to suit the majority of wall sockets used around the world.
Using the Receiver Unit Connect BE9122 Bellman Stereo Headphones, BE9128 Bellman Neck Loop, BE9125 Bellman Stetoclip, BE9124 Bellman In-ear Phones or another listening product recommended by Bellman & Symfon to the headphone output (13) on the right-hand side as illustrated in the fold-out section of the manual. Switching on the Receiver Unit Press the On/Off button i (6). The Battery Status LED (3) starts to shine with a green light to indicate that the unit is on.
Selecting the tone Use the tone control’s < button (11) to reduce and the > button (12) to increase the treble in the tone. The Volume and Tone LED Indicator (8) shows the selected setting. The LED indicator goes out 5 seconds after the sound quality has been set. DE DK EN ES The Receiver Unit can be used as a small and adaptable self-contained call amplifier, but together with the Transmitter Unit it opens up a whole new range of possibilities.
Listening via the Transmitter Unit To listen on the microphone in the Transmitter Unit press the R button (7) on the Receiver Unit. The external sound LED (4) comes on and the sound detected in the Transmitter Unit is now heard in the headphones. Listening on the Receiver Unit’s microphone again If you want to switch back to the internal micro-phone, give a short press on the M button (5).
OFF 1s OFF 1s Switching off When you have finished you can switch off the Transmitter and Receiver Units by pressing the On/Off buttons i (6, 18) and holding them down until the Battery Status LEDs (3, 17) go out. DE DK EN ES Choice of microphones Bellman Audio Domino contains two microphone options so that you can easily switch between an omnidirectional and a directional microphone. FI FR IT JP The microphones on both the Receiver Unit and Transmitter Unit have this function.
Choice of microphone on the Receiver Unit You can switch between omnidirectional and di-rectional microphone reception by pressing the M button (5). The omnidirectional microphone is indicated by the Microphone LED (2) lighting up green and the directional microphone by it lighting up orange.
External sound source If the audio cable supplied, (which has a small 2.5 mm jack plug on one end), or if the External Microphone is connected to the Transmitter Unit’s external sound source input (20), the Transmitter Unit’s internal microphone will be disconnected and the external sound source will be automatically selected. The Battery Status LED blinks orange several times to confirm that an external sound source has been connected.
In some cases it may, for example, be easier for a lecturer to have an external microphone and a Transmitter Unit in his/her pocket than to speak in a loud voice or carry a wired microphone. A Transmitter Unit can transmit speech to one or more Receiver Units at the same time. The input sensitivity is automatically adjusted to a suitable amplification when an external microphone is connected.
The sound from the Transmitter Unit is mixed with the sound from the internal microphone. You can adjust the balance between the Receiver Unit and the Transmitter Unit’s microphone by holding down the M button(5) at the same time as setting the balance using the < (11) or > buttons (12). DE DK EN ES FI FR IT If you want to go back to listening on the Transmitter Unit, press the R-button (7) and if you want to switch over to listening on the internal microphone, press the M button (5) instead.
Battery indicator The Battery Status LED (3, 17) normally lights up green. This indicates that the unit is switched on and the battery level is satisfactory. When the battery is low, the Battery Status LED (3, 17) blinks green until the battery is almost completely flat when it blinks orange instead. As soon as it blinks green it is time to charge the unit again. If the unit is not charged, it is switched off automatically.
Proceed as follows to establish a temporary radio link between a transmitter and a receiver: • • • Start both the units with the On/Off buttons i (6, 18). Hold down CONNECT (19) on the Transmitter Unit. Hold down both the M button (5) and the R button (7) on the Receiver Unit. 5s 5s A ”running light” on the Receiver Unit’s Volume and Tone LED Indicator (8) moving towards the centre indicates that the link has been established.
Troubleshooting in brief Problem Nothing happens when you try to start the units. Solution Connect the charger and check that charging starts within 10 seconds. Please note! If charging does not start within 10 seconds, disconnect the charger immediately and contact the nearest dealer! No sound can be heard in the headphones when the Receiver Unit is switched on. Turn up the volume using the volume control (9).
Problem Solution Connect the radio link and check that the connection is made without problems. Check that the Transmitter Unit can switch between the omnidirectional and directional microphone position. Check that the sound source is correctly connected to the Transmitter if the stereo cable is connected to the External Sound Source Input (20). A high-pitched noise is heard in the headphones. The sound breaks up or comes and goes.

Appendix Settings Bellman Audio Domino has more settings than those you can access in user mode. By going into the Settings Menu you can adjust settings that you do not normally need to change or which are adjusted when first used and never need to be changed again. Settings menu Start the Receiver Unit with the On/Off button i (6). Hold down the On/Off button i (6) and press the Volume Button - (10) within 1 second until the RF LED (4) starts to blink.
Overview of the Settings Menu In the settings menu you can move between the different settings by pressing the R button (7) or the M button (5). Each press on the R button moves you clockwise on to the next setting in the list and the M button takes you anti-clockwise to the previous setting in the list. 8s When you have finished adjusting your settings, give a short press on the On/Off button i (6) to return to normal user mode.
Balance control The balance between the right and left-hand channels can be set to compensate, for example, for a hearing loss in one ear. Press the < button (11) to adjust the balance on the left and the > button (12) to adjust the balance on the right. The standard setting is centred balance. Basic attenuation Different headphones have different sensitivity levels and you can compensate for this with basic attenuation.
MAX Use the < button (11) to reduce the basic attenuation (increase the volume) and the > button to increase the basic attenuation (reduce the volume). The basic attenuation is adjusted in increments of 3 dB. The standard setting is 0 dB attenuation, which corresponds to the maximum output signal. STEREO Stereo/Mono The line-in signal can be rendered in either Stereo or in Mono. The speech intelligibility can be increased in certain listening situations such as when watching TV if the signal is in Mono.
Bass reduction Low-frequency interference such as fans and road noise can be tiring if you are exposed to it for a long period. By activating bass reduction, low-frequency interference and sounds are reduced. BASS Press the + button (9) to activate Bass Reduction. BASS Press the - button (10) to deactivate Bass Reduction and get level frequency response. The standard setting is deactivated Bass Reduction.
Adjusting the Tone Control The Tone Control Blocking function has been developed in case you want to make it easier for the user to use Bellman Audio Domino. This setting can be used to choose whether the user should be able to adjust the tone control or not. If you choose to switch off the tone control buttons, you can preset the tone control that will be used in user mode.
Please note that if the tone control is on, the preset value will be changed as soon as the Tone Control is changed in user mode. 8s Resetting to the factory setting You can use this to reset all settings to the standard settings that the products were supplied with from the factory. Press and hold down the + button (9) until all the LEDs on the display are lit. After resetting is completed, the display will blink for a short period.
Pairing of units The Transmitter and Receiver Units in the Bellman Audio Domino system must have the radio link established in order for radio communication to operate. To make it easier to get started, a Receiver Unit and a Transmitter Unit which are paired together are always supplied so that they will work together. Where you want to pair a Receiver Unit with a Transmitter Unit which is different from the Receiver Unit it was originally supplied with, you can do this in the Settings Menu.
Please note! If you pair up a Transmitter Unit and a Receiver Unit in the Settings Menu, this replaces the pairing carried out in the factory. This can be useful when changing a Transmitter Unit under guarantee or if you want to pair up several Receiver Units to a Transmitter Unit (e.g. in a conference room).
