Roomperfect™ Troubleshooting; Cleaning And Maintenance - Lyngdorf Audio TDAI-1120 Owner's Manual

RoomPerfect™ troubleshooting
The calibration microphone is very sensitive and may pick up unwanted noise, including subsonic signals
and background noise, which disturbs the measurements. If the signal is disturbed it will take longer for the
system to make a correct measurement.
A measurement that has been disturbed by noise but completed will always be correct; it is not necessary to
redo it. If the measurement has stopped due to an error, one of the following error messages will be shown.
Signal error! Check microphone and cable, then press enter
No microphone is connected, or the microphone cable is defective. Check that the microphone cable is
connected to the microphone socket on the back panel. If the problem continues, test the microphone cable
by connecting the microphone directly to the microphone socket and select Retry.
If the microphone is detected, replace the microphone cable and retry the measurement.
Error: Signal clipping - or - Error: Too much noise
Either the incoming signal has been classified as too loud, resulting in clipping or distortion, or a loud noise in
the immediate environment has corrupted the measurement results. If a loud noise has in fact occurred,
such as the sound of a closing door, reduce noise levels inside and in the immediate vicinity of the room and
repeat the measurement. If no loud noise has occurred, reduce the volume of the signal and repeat the
measurement.
Error: Signal too low
This error message is displayed when the measurement has lasted more than 5 minutes for the low-
frequency signal or more than 2 minutes for the high-frequency signal. This happens most often when using
a low-level measuring signal compared to the background noise in the listening environment, which results in
prolonged measuring times. Raise the measuring signal volume or reduce the noise in the environment
before continuing with the measurement.

Cleaning and maintenance

The TDAI-1120 does not require any regular maintenance except to keep its exterior clean. Simply wipe it
with a clean, soft cloth. A small amount of non-abrasive cleaner may be used on the cloth to remove any dirt
or fingerprints. Do not use abrasive cleaners or cleaners containing liquid solvents.
