Audio adjustments
Audio level and ringtone volume can be adjusted during conversation by
means of special controls (see chapter \ on page 2.11). Normal audio
levels are set in the factory; settings on the back of the device must be
changed only if really necessary.
Setting the sound levels.
- If audio is excessively intermittent during the conversation or the
speaker tends to distort it during the call, it is recommended to slightly
change the microphone sensitivity using the SENS trimmer on the
back of the video-intercom.
- In case of problems in getting the audio in one of the two directions,
slightly increase the level of the disturbed channel and decrease the
level of the other channel using the
phone volume.
