If there more than two identical digits are to be transmitted the repetition tone is appended to the digit
tone (e.g., 22222 is transmitted as f2 fw f2 fw f2, where f2 is the tone for "2" and fw is the repetition
tone).
For MODAT mode having nominal tone durations of 40 ms, the duration of a single tone may vary ± 5 ms.
Decoding the selective calls is started by clicking on a system. If transmission and system selection con-
form, the call sign is displayed on the monitor. In the Options menu a Time stamp function can be ena-
bled to add date and time to each call.
