Supplied with the transmitter are one neck strap and one chest strap. [. . . ] His neighbourtalking) thanks to an 8-pin microphone socket to which (Ior example) the plug-in microphones MKE 2012 or MKE 4012 can be connected. By means 01the appropriate switch, the receiver can be set lor two different modes 01operation: a) Inlrared reception + microphone and b) inlrared reception + microphone automatic. II a hearing-aid is plugged into the microphone socket, an automatic lade-out device built into the receiver ensures that the level 01the microphone situated in the hearing-aid drops by around 20 dB every time a signal (e. Speech or music) is received lrom the transmitter. Like the inlrared transmitter, the receiver EKI1 011 can also be powered Irom either three Mignon batteries or lrom rechargeable Mignon accus. II accus are used, these can be recharged in the charger SZL 1011 via the two charging contacts situated one on either side 01the receiver. Included in the packaging 01the receiver are one neck strap and one chest strap. CD Open battery compartment by following first A and then Band insert batteries. (2) Hook the neck strap into the corresponding notches and lock into position by pulling upwards resp. In orderto avoid this, here are a lewtips on inlrared transmission in general: The invisible inlrared light still obeys the same laws as visible light. A dark sur/ace, it will be partially or totally absorbed and il it hits allat, white sur/ace, a large proportion olthe inlrared light will be reflected. Normal window panes are no obstacle lor inlrared light. On the SKI1 011 , the inlrared emitter diodes are arranged in such a way that a large part 01the inlrared light reaches the receiver EKI1 011 by reflecting off the walls and ceiling. This ensures that the room in question is illuminated in an even manner. The conditions lor the propagation 01 inlrared light can be regarded as being optimal when: 1. And when the walls are not hung or covered with any light-absorbing materials or objects. For illuminating rooms with a floor space greaterthan 30 m2 it is necessary to use one or more transponders (inlrared light impulse ampliliers) 01the type SZT 1011. The transponder picks up the inlrared signal emitted by the transmitter with its own array 01 receiving diodes, amplilies it and transmits it lurther.
