Temperature

The temperature of a venue also plays a crucial role in affecting the Room delay. The SR 400 D allows you to enter in

the current room temperature. Once the correct temperature is entered, the SR 400 D will re-calculate the Room

delay so the correct delay is used.

The procedure for changing the Temperature of the SR 400 is as follows:

From performance mode, press the <Utility> button and use the <Bypass> and <Mode> button to scroll to the

Temperature setting. Now depending on the Temperature Unit Selection (Page 6), the the temperature will either

read in Celsius (0 to 30 degrees)or Fahrenheit (32 to 86 degrees). Now use the <Data Wheel> to select the

desired temperature. Once selected, the SR 400 D will re-calculate and the correct Delay is heard.

Note: This utility function can only be used when the Delay Unit is being measured in Feet or Meters.

To Factory reset the SR 400 D to its original default settings, you must perform the following procedure.

Press and hold the <Bypass> button while supplying power to the unit. The display reads: Reset SR 400D? Now

release the <Bypass> button and press the <Delay 2> button. The SR 400 D will now be returned to its original

default settings.
