3. Multiply the lengths of the cables between the transmitter and each radiator with the
cable signal delay per meter. These are the cable signal delays for each radiator.
4. Determine the maximum signal delay.
5. Calculate for each radiator the signal delay difference with the maximum signal delay.
6. Divide the signal delay difference by 33. The rounded off figure is the signal delay switch
position for that radiator.
7. Add delay switch positions for radiators under a balcony, if applicable (see section
Systems with more than 4 carriers and a radiator under a balcony, page 50 ).
8. Set the delay switches to the calculated switch positions.
The next figure and table illustrate the calculation of the cable signal delay.

Notice!
*The used cable signal delay per meter is an example. Use the actual signal delay per meter in
this calculation as specified by the manufacturer.
Determining delay switch positions by using a delay measuring tool
The most accurate way to determine the cable signal delays is to measure the actual signal
delay for each radiator as described in the following procedure:
1. Disconnect the cable from a radiator output of the transmitter and connect this to a delay
measurement tool.
2. Disconnect a radiator from this cable.
