KONFTEL - telefon audiokonferencyjny FAQ

I hear no sound from my Konftel. What is the problem?
* Check that the telephone is turned on. The green microphone indicators should be lit.
* Check the connections:
   Analogue connection: Check that the POTS network cable is connected between the POTS connection input and an
   analogue telephone jack.
   Digital connection: Check that the ISDN network cable is connected to an ISDN connection input and a digital jack
   (ISDN/So).
* Bypass any extension cables and see if the system works correctly.
* Disconnect the extra microphones and see if the Konftel 200/NI works without them. If the Konftel 200NI needs to wait
   for a second dialling tone, you should enter a pause using the pause/mute button when you enter the telephone number
   before calling or in the telephone book.

   telephone number as an instruction or in the telephone book. If this does not help, contact your retailer or our technical
   support.

I have a Konftel 50/60W/100/D and get no sound. What is the problem?

* Check that the telephone is turned on. The LEDs should be lit.

* Trim the Konftel 100/D manually by pressing the volume buttons + and – at the same time. With the Konftel 50 and 60W,
press the Trim button.

* Check that all cables are properly connected. Disconnect any extension cables and see if the system works. If not,
contact your retailer.

* If you have connected the Konftel 50, 60W or 100/D to a PC, check that the sound card and software are capable of Full
Duplex. Also check that you have connected the Y cable plugs to the right output on your PC. See the user instructions,
under Volume settings.

* Check that the party you are calling or connecting to has a conference unit, sound card, and software that is capable of
Full Duplex, and has sufficient capacity (bandwidth) on their connection. If this does not help, contact your retailer or our

What is the difference between a normal speakerphone and a Konftel telephone?

All Konftel telephones have OmniSound^®audio technology, which includes Full Duplex and 360 degree audio pick-up and reproduction. Full Duplex means that you can talk simultaneously, so-called double direction speech communication, without clipping the audio signal. In other words, you can hear your conversational partner while you are talking yourself. With your normal speakerphone you have surely noticed that you sometimes lose words, sometimes even entire sentences during a call. This doesn’t happen with Konftel’s telephones.

The sound is too faint sometimes, what should I do?

Adjust the speaker volume on the keyboard.

The person on the other end who called in to the meeting thinks I sound faint/too loud, what should I do?

If you have a Konftel 50, 60W or 100/D the microphone volume can be adjusted. Increase/decrease the volume a notch as shown in the instructions in the user guide, under Volume settings for microphones.

When connecting the telephone clicks one or more times. What is the problem?

There is nothing wrong. All Konftel telephones make this noise at the beginning of every call. Either once or three times. When this click occurs, a room calibration takes place to ensure that the telephone works perfectly in your room. When the click occurs three times, it is because the room has difficult acoustics, such as a long echo (longer than 0.5 seconds) or the level of background noise is louder than 45 dBA. Because of the environment, the telephone does not then provide optimal performance.

I hear an echo during the call. What should I do?

Perform a manual room calibration (trimming). This is heard as static of about 0.5 seconds in length. From the remote or the keyboard, do the following:

* Konftel 50 and 60W: Press the Trim button.

* Konftel 100/D and 100/R: Press the + and - volume buttons simultaneously.

* Konftel 100, 200 and 200NI: Press the volume buttons (down arrow /up arrow) simultaneously or press the trim button on
the remote.

The person on the other end who called in to the meeting says they hear an echo, what should I do?

First perform a manual trim, see the question above. If you have a Konftel 50, 60W or 100/D the microphone volume may be set too high. Decrease the volume a notch as shown in the instructions in the user guide, under Volume settings for microphones.
