The Radio Signal Test Program allows checking the correct functioning of radio transmission
between photocells and the display board, as well as the signal power (0-100%).
Enter the P98 program and generate an impulse interrupting the photocell/reflector beam. If
nothing appears on the display board, check (and change) the transmission channel as per
program P99 (see chap. 2.20).
If the impulse is received, on the left side a counter is shown which increases with each impulse
and on the right side the percentage indicating the signal power.
To begin a new test press the yellow L

ESET
button, in order to reset the counter and
percentage.
