➇ Microphone

Behind the front cover, a high quality electric microphone can be found for a clear

speech transmission. Hold the device at a distance of some 5-10 cm from the

mouth and speak at a normal volume. Speaking too loudly can lead to distortion

and as a result to a decline in understanding. Also, the range will not be greatened

through loud speech. If an external microphone is put in the MIC socket above, the

internal microphone will be turned off automatically.

€ Loudspeaker

Behind the front cover, a high quality loudspeaker can be found for clearly spoken

reports. Turn on the volume VOL on the top for the best report. Too great a volu-

me can lead to the distortion and also to a deterioration of understanding. Also,

the electricity consumption will increase. If an external loudspeaker is put in the

SPK socket on the top, the internal loudspeaker will turn off automatically.
