OTHER FUNCTIONS
Reconnection
bluMe Duo can remember up to 2 devices paired previously, and will attempt to
pair with the last connected devices automatically once it is turned back on.
bluMe Duo will not initiate reconnection. If bluMe Duo itself is turned off, it is
recommended to turn it back on first before turning on the paired devices so
that it can accept the incoming Bluetooth connection from the devices.
Adjusting the Volume
bluMe Duo, by design, is a passive transmitter or receiver and has no volume
control. User volume level must be adjusted via the input and output sources
connected to bluMe Duo.
Volume can be individually adjusted on each set of headphones paired with
bluMe Duo using the built-in volume controls on the headphone. With some TVs
and connection options, TV volume may be further raised or lowered to
change the volume of all headphones paired with beamit. In this case, volume
should be maximized on the TV and then adjusted via headphones for best
audio quality.
Factory Reset
With bluMe Duo powered OFF, press and hold the MFB for approx. 10secs until
the display shows “Reset Device”. The unit will enter pairing mode and any
previously paired devices will be cleared from its memory.

TROUBLESHOOTING TIPS
Unable to pair and connect bluMe Duo to my Bluetooth device.
Make sure you are operating bluMe Duo in the appropriate Bluetooth mode.
In TX Mode: bluMe Duo can only pair with a Bluetooth receiving device such as a
Bluetooth headphone, speaker or receiver. In this mode, ensure that bluMe Duo
and the Bluetooth headphone, speaker or receiver are in pairing mode at the
same time and are within 1 meter (3 feet) of each other.
In RX Mode: bluMe Duo can only pair with a Bluetooth transmitting device such as
a smartphone, tablet or computer. In this mode, ensure that Bluetooth is turned
‘ON’ on your smartphone, tablet or computer. Make sure bluMe Duo is ready to pair
and your device and bluMe Duo are within 1 meter (3 feet) of each other.
My Bluetooth headphone is connected but there is no audio output.
1. Ensure that your audio source (TV) OUTPUT is properly connected to bluMe Duo
audio INPUT. Audio inputs are used with TX MODE only.
2. Check whether the audio input source is correctly selected on bluMe Duo
(AUX / OPT). If AUX is selected, make sure your audio source is connected to the
AUX input. If OPT is selected, make sure your audio source is connected to the
Optical input.
3. Confirm that audio is playing on the TV and the volume is set to “High” on the TV.
Make sure that the volume is sufficiently high on your Bluetooth headphone/speaker.
4. If you are using an Optical connection, make sure nothing is connected to
the AUX input of bluMe Duo.
16
Smartphone is connected but cannot hear any sound from my audio system.
1. Ensure that your audio source (Home audio system, stereo speakers, etc.)
INPUT is properly connected to bluMe Duo audio OUTPUT. Audio outputs are
used with RX MODE only.
2. Check whether the audio output source is correctly selected on bluMe Duo
(OPT / AUX). If AUX is selected, make sure your audio source is connected to
the AUX output. If OPT is selected, make sure your audio source is connected
to the Optical output.
3. Verify the volume levels on your audio system and player app.
4. If you are using an Optical connection, make sure nothing is connected to
the AUX output of bluMe Duo.
The volume output level is Low.
In TX mode: Adjust the volume both on your Bluetooth headphones / speakers
and on the TV or other connected device as both may control the volume.
In RX mode: Verify the volume levels on your smartphone / computer OS and
player app. Also check the volume levels on your powered speakers or stereo
system.
The sound quality is poor and / or the audio is cutting out.
1. For the most noise-free audio, maximize the volume on your audio source (TV ,
home audio system, powered speakers, etc.) and adjust volume via the Bluetooth
enabled headphones, speakers or smartphone.
17

2. Make sure you are within range of your Bluetooth-enabled device.
3. Bluetooth devices are susceptible to interference from other Bluetooth
devices, cordless phones, routers, microwave ovens, and wireless devices
operating on the 2.4 GHz band. Eliminate as many potential sources of
interference as possible while using your Bluetooth headphones / speakers.
There is a delay (latency) in audio
1. Bluetooth is a digital wireless signal and there is some latency expected due
to the coding/decoding and compression/decompression steps that must occur.
2. The aptX® Low Latency audio codec supported by bluMe Duo is notable for
having a much lower latency (smaller delay), compared to regular Bluetooth audio.
3. Using bluMe Duo with a headphone that supports aptX® Low Latency will
minimize audio lag.
4. Some modern TV’s and receivers also have an audio delay option. Make
sure that audio delay is set to 0 to minimize lag.
