Safety information The 2 x 1:8 active antenna splitter must only be set up and connected by an electrical engineering expert. Never open electronic units! This must only be done by authorized personnel and is all the more important for units connected to AC outlets. If units are opened by customers in breach of this instruction, the warranty becomes null and void! Make sure that the air vents of the unit are not covered or blocked.

Putting the unit into operation Setting up the unit The unit is suitable for use as table top or can be mounted into a rack. 왘 Fix the unit to a 19" rack by using the supplied rackmounting kit. 왘 To set up the unit on an even, horizontal surface, fix the four self-adhesive plastic feet to the base of the unit. Note: Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics.
If you use passive antennas only, the DC supply voltage can be turned off. To do so, remove the two input modules (see “Exchanging the input modules” on page 7) and set the two switches DC-Feed ANT A and DC-Feed ANT B 쐈 to position “OFF”. 쐈 Connecting the receivers Up to eight receivers, e.g. EM 3031, or eight twin receivers, e.g. EM 3032 or EM 3532, can be connected.
When using the selective input modules: y Make sure that all transmitters and receivers of your transmission system operate within the frequency window of the selective input modules! When using the wideband input modules: y Use an active antenna (e.g. A 12 AD antenna) or an antenna with antenna booster (e.g. GZA 1036 antenna with AB 1036 antenna booster). To exchange the input modules: 왘 Use a crosstip screwdriver to loosen the screw of the catch for the input modules 쐆.
Trouble shooting The LED POWER 쐋 does not light up The unit is not powered.
