One-way Audio
It is possible that you have one-way audio, i.e. you don't hear anything either on the Behnke Station or the phone on the other side. This can have different causes. To localize the problem, please proceed as follows:
1. Audio test
An automatic audio test can be carried out on the web interface to check whether there is a problem with the Behnke Station's speaker or microphone. To do this, simply switch to "Acoustics" in the menu on the left. There you will find the audio test in the "Audio" section. Simply click on the button trigger.
While the audio test is running, the Behnke Station tries to output a sequence of tones via its speaker, which is then recorded again via the microphone. If this doesn't work, there is most likely a problem with either the speaker or the microphone. The result of the test is displayed after a few seconds below the trigger button:
- audio test ok: if the audio test is passed, there is most likely no problem with the speaker and/or microphone. In this case, please continue with step 3 on this page (Generating diagnostics).
audio test failed: if the audio test fails, there could be a problem with the speaker and/or microphone. In this case, please continue with step 2 (Checking speaker/microphone) on this page.
2. Checking speaker/microphone
If the audio test failed in step 1, the Behnke Station's speaker and microphone should be checked. Maybe they are not connected correctly or one of the components is defective. If you know whether the sequence of tones could be heard on the Behnke Station during the audio test, a problem with the speaker can be ruled out.
2.1 Checking the connection
It's possible that the speaker and/or microphone were simply incorrectly connected when installing the Behnke Station. To check it, simply remove the electronics box from the Behnke Station and check the connection panel. If necessary, connect the components correctly.
2.2 Checking for defect
If the speaker and microphone are connected correctly but the audio test still fails, there could be a defect. If you have a multimeter handy, you can check the speaker/microphone for a defect by measuring the impedance:
-
The speaker should have an impedance from 6 to 8 Ω. If the impedance is lower or higher, the speaker is defective.
-
The microphone should have an impedance of either 800 Ω or 1.6 kΩ. If the impedance is lower or higher, the microphone is defective.
If you have found a defect in one of the components, please contact our sales department (auftrag@behnke-online.de) or the supplier who sold you the Behnke Station, stating the delivery note/invoice number.
3. Generating diagnostics
If the audio test was successful or you can rule out a hardware problem with the speaker/microphone, we need the Behnke Station's diagnostics for trouble shooting. Before you download the diagnostics from the Behnke Station, it should be ensured that the error (call with one-way audio) occurred shortly before, so that the error can be seen in the diagnostics. If in doubt, simply trigger a faulty call again, with both sides speaking into their microphones if possible.
Then call up "Diagnostics" on the Behnke Station's web interface in the menu on the left. There you simply click on the download button in the "Log" section and send in the file. You can create a support ticket via the following link, after which you will immediately receive a reply. You can then simply reply to this e-mail and attach the diagnostics file.
