the track, and that the four socket-head-cap screws on the weather cover are

The Radio Test option is used to broadcast a short message through the speaker (inside the
SmartScanIS enclosure) and through the radio. Similarly, the 1KHz Test Tone option is used
to generate a continuous tone for about 15 seconds through the speaker and the radio. Using
either of these options will let you verify that the speaker and radio are working properly.
At single-track sites, the text of the message is "Testing, U-P detector, milepost (milepost
number), testing, one, two, three, four, five, four, three, two, one, testing detector-out." At
double-track sites, the text of the message is "Testing, UP detector, milepost (milepost
number), track (track designation), testing, one, two, three, four, five, four, three, two, one,
testing, detector-out."
