Abstract (en)
The invention relates to a procedure used in an elevator, whereby the brightness and sound volume of the signalling of the signal devices are controlled on the basis of the background illuminance and the noise in the environment. The intensities of the background noise and illuminance are measured before the signalling and the values obtained are compared with given reference values (12 and 13). Based on these, the brightness and sound volume of the signalling are adjusted to suitable values by volume and brightness control units (4,5; 6,7). <IMAGE>
