BLUETOOTH: (MODE key)
Your appliance allows the reception of audio signals sent since any devices having a
Bluetooth transmitter (Smartphone, tab, computer…).
First time association:
- Activate the Bluetooth connectivity of your emitter device;
- Select your appliance on the list of possible receiver (named ATOLL HD120);
- With key of the remote or with keys SEL +/- (18) of the front panel, select the
Bluetooth input of your HD120 (led 15 lighting in blue).
The whole audio signals which will be read on your device source will then be
transmitted towards your HD120. Your emitter device will remain associated until
you switch off your HD120 but he will remain visible for your emitter.
Association of another emitter:
Once associated to an emitter, you’ll need to switch completely your HD120 off in
order to make it visible from another emitter.
The quality of reception of the signal can be dependent on the power of the Bluetooth
emitter and the distance between the 2 devices. Avoid being up to more than 5 meters
of your HD120 for a correct reception without any risks of signal cuts.
