PERSONAL HEARING SYSTEM
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 to be
changed again.
Settings menu
Start the Receiver Unit with the On/O button (6) for about 3 seconds.
Hold down the On/O button (6) and press the Volume Buttton (10) within 1
second for at least 3 seconds.
You are now in Balance Control mode.
Overview of the Settings Menu
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.
Basic attenuation
Different headphones have different sensitivity levels and you can compensate
for this with basic attenuation. What you actually set is the attenuation you
require at the maximum power output you want to have (which is therefore 0dB
attenuation). This setting is useful when you want to adjust the maximum
volume in user mode for a pair of headphones or in-ear phones with a higher
sensitivity than the BE9122 Bellman Stereo Headphones or, for example, if you
want to limit the volume for a child.
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.
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.
The standard setting is tone control activated.
Activating and deactivating Tone Control in User Mode
Press the + button (9) to activate the tone control buttons and the –
button (10) to deactivate them.
Presetting the Tone Control
Press the < button (11) and the > button (12) to preset the tone control to
the level that will be used in user mode.
The standard setting is Tone Control centred (level frequency response).
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.
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.
Version information
The product version information is presented here via a pattern of lit and
blinking LEDs. This internal information is only intended as an aid for
servicing and support.
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. Proceed as follows to pair up the units:
- Start both the units with the On/Off buttons i (6, 18).
- Go into the Settings Menu.
- Hold down the CONNECT button (19) on the Transmitter Unit.
- Hold down both the M button (5) and the R but- ton (7) on the Receiver Unit.
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.
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).
Educational Mode
The Domino Pro has a mode especially developed for use in an educational
setting.
This mode sets the microphone in the transmitter to be active by default.
The microphone in the receiver can be momentarily activated to allow
conversation with peers and support staff around the user.
- By pressing and holding the MIC button, the sound from the local microphone will be mixed with the sound from the transmitter microphone
- When the MIC button is released, the receiver will go back to the transmitter microphone again
Turn On the Educational mode
- Enter the “Settings menu” (refer to Page 314)
- Use the MIC (5) button to move between settings until the LED’s over the MIC (5) and RF (7) buttons flash (this is the “Resetting to the factory setting” menu).
- Press and hold the Volume down button (10) for 20 seconds.
- The LED lightbar will flash to acknowledge the change of mode.
- Press the power button once shortly to set education mode and return to the normal menu.
Turn Off the Educational mode
The Educational mode is turned OFF by restoring Factory settings (refer to
Page 320).
Note: The factory default setting is Educational mode OFF.
Testing
It is easy to test the Bellman Audio Domino Personal Hearing System. If Bellman Audio Domino does not operate as described below, you can carry out further troubleshooting as instructed under Troubleshooting.
How to test
The testing of Bellman Audio Domino has been divided into three parts. One
part for the Receiver Unit for which only the Receiver Unit is required, one
part for the Transmitter Unit for which both units are required and finally
one for charging the two units.
Receiver Unit
- Switch on the unit and make sure that the Battery Status LED (3) lights up green.
- Connect the headphones to the Headphone Socket (13) and scrape carefully on the round microphone (1) with your finger and check that there is a scraping sound in the headphones.
- Press the M button (5) and make sure that the Microphone LED (2) changes color and lights up orange.
- Scrape carefully on the small microphone hole on the top (1) and the round microphone (1) with your finger and check that there is a scraping sound in the headphones.
- Press the buttons (9, 10, 11, 12) and check that the Volume and Tone Indicator changes.
Transmitter Unit
- Switch on the unit and make sure that the Battery Status LED (17) lights up green.
- Press the R button (7) and make sure that the External Sound LED (4) lights up green.
- Carefully scrape on the round microphone hole (16) on the top of the Transmitter Unit with the finger and check that there is a scraping sound in the headphones.
- Press the R button (7) and make sure that the External Sound LED (4) changes colour and lights up orange.
- Carefully scrape on the round microphone (16) on the Transmitter Unit with the finger and check that there is a scraping sound in the headphones.
- Connect an external sound source to the External Sound Source Input (20) and check that the sound from the sound source is heard in the headphones. The external sound source input (20) can be tested, for example, by connecting a CD player or a radio to the input via the audio cable supplied. The transmitter unit automatically switches to an external sound source when a connector is connected to the External Sound Source Input (20).
Charging
- Connect the charger to the mains socket and check that the LED on the charger light up green.
- Connect the charging cables to both the charger and to the charging sockets on the Receiver Unit and the Transmitter Unit (14, 21), see the fold-out section of the manual.
- Check that the LED on the charger change from green to red.
- Check that the Battery Status LEDs on both the Transmitter Unit and Receiver Unit light up orange.
