Poor sound quality, echo
1. Check the position. The unit is designed to stand flat on the table. Avoid
moving it around during call. Neither should it be placed too close to a wall or
under objects such as lamp shades or leaves from potted plants.
2. Trim Konftel 50 manually. See the page on manual trimming.
3. Is the volume setting correctly set? See page on volume setting for
microphone.
4. Does the receiving party have a conference unit, sound card or software
which cannot handle full duplex?
5. When the unit is connected to a PC, radio frequency interference may cause
discernible sound. The sound will end when the interference stops.
Can I connect a headset?
Instead of a handset you can connect a headset to the switchbox. You may now
switch between making a call via the headset or Konftel 50 via the On/off button.
Note that the headset must be adapted to suit your telephone system.
Calls are audible through the PC headset but not through Konftel 50.
Check that the software and sound card can handle full duplex.
Maintenance
Clean the equipment with a dry, soft cleaning cloth. Do not use fluid!
