Possible malfuctions and her cause. software reset
Very slow pairing or no pairing possible:
In the near of strong W-LAN hotspots, the usable frequencies may be overloaded; pair
the devices outside these ranges.
Device out of range, connection lost, LEDs flash 2 x red:
If the connection is not restored automatically, reduce the distance within ¼ hour. In the
receiving area, the devices should then connect again.
Disturbances and interruptions:
Radio waves in the frequency range used (2.4 GHz) reflect very strongly on buildings,
etc., and there is constant interference during the change of location and thus field
strength fluctuations. As a result, disruptions and crashes are possible.
If the team leader makes a call in multi-user mode, no other participants should be on the
phone at the same time; otherwise, it may not be possible to reconnect to them.
Speech is too quiet or microphone does not turn on:
Check the microphone arrangement, the mic. should have lip contact.
Noise, etc .
Reduce the volume, at very high volume settings system typical signals (noise, soft
singing, etc.) can be heard.
Feedback effects:
Turn down the volume and turn on the electronics only if the earmuffs are used properly.
Inexplicable malfunctions, device no longer reacts:
Switch the devices off and on again, if this is not possible, charge the battery, when the
USB plug is plugged in a software reset is automatically performed. If this does not help
either, delete the memory, see next section.
Secure deletion of existing pairings and settings
