AURAL WARNING SYSTEM - TEST
General
The aural warning system test checks the aural warning module for correct operation. You hear the intermittent horn and the clacker sounds for a good test.
A test switch is on the top of the aural warning module. The test switch is spring loaded so that it returns to center when it is released. Use a screwdriver to turn the switch. Turn the switch clockwise to test channel
A. Turn the switch counterclockwise to test channel B.
Turn the switch to hear the intermittent horn. Release the switch to hear the clacker.
The clacker stops at the end of the test.
