The base station is switched off or in an unknown state.
Unplug the USB cable from the base station while leaving the power adapter plugged in, then reconnect it to the base station after 30 seconds. The pairing LED should then flash and remain lit once the connection to OSKAR easy has been established.
Problem with the power adapter.
To investigate further, use a different USB-C power adapter with an output current of at least 2 A and a different USB-C cable.

No sound – LEDs are flashing
The pairing LED
on the base station and the status LED
on OSKAR easy flash after switching on or occasionally during operation.
Possible cause
Possible solution
The wireless connection between the base station and OSKAR easy is unstable or affected by other wireless sources. Devices such as smartphones, Wi-Fi access points and microwave ovens generate radio waves and may cause radio interference.
Place OSKAR easy and the base station at a sufficient distance from such devices. Disable Bluetooth or Wi-Fi on those devices when not needed. If necessary, pair the base station and speech amplifier again.
Sound interruptions or no sound from OSKAR easy
Possible cause
Possible solution
OSKAR easy is too far from the base station, for example in another room.
Reduce the distance to the base station.
The sound is too quiet
The sound is too quiet even though OSKAR easy's volume is set to maximum.
Possible cause
Possible solution
The TV's output volume for the connection in use is set too low.
Check the output level in your TV's sound settings and increase it or set it to maximum.
The TV's output level may be fixed and linked to the TV's volume control.
Set the TV volume to a high level (usually ¾ of the maximum) and adjust the desired volume on OSKAR easy using only its control. This also ensures that OSKAR easy receives a sufficient signal level to operate.
The sound is distorted
OSKAR easy's sound is distorted when the TV's headphone output is used.
Possible cause
Possible solution
The signal sent to the base station is too high.
Check the output level in your TV's sound settings and reduce it. Check that the sound is not distorted even when OSKAR easy's volume control is turned up.
A high output signal is being sent to the base station, and the output level is linked to the TV's volume control.
In this case, set the TV volume to a lower level and adjust the desired playback volume on OSKAR easy using only its volume control. Check that the sound is not distorted even when OSKAR easy's volume control is turned up.
A humming noise is heard during playback
Possible cause
Possible solution
The AUX cable is not plugged into your TV's AUX or headphone socket.
Check that you are using the correct socket on your TV.
The AUX cable is not fully inserted into the base station or TV.
Make sure that both ends of the cable are fully inserted into the corresponding sockets.
The TV socket is oxidised/dirty and has poor contact.
Insert the cable into the TV socket several times. Repeated insertion may improve contact.
TV sound and OSKAR easy sound are not synchronised
This may occur when using an optical connection.
Possible cause
Possible solution
The TV sound is not muted. The built-in TV speakers are still active.
Mute the TV sound or set its volume to 0.
ℹNote:
Disable the built-in speakers in your TV's sound settings (audio output selection). For optimal speech intelligibility, we recommend switching off the TV speakers' sound while using OSKAR easy. If you still wish to listen to both at the same time, a delay may occur. Enable “Audio delay” in your TV's audio settings and select a value that synchronises TV sound and OSKAR easy sound. Refer to your TV's user manual for this.
The battery is not charging
Possible cause
Possible solution
OSKAR easy is not making charging contact with the base station.
Clean the charging contacts with a soft cloth. To avoid malfunctions, do not press too hard on the charging contacts.
