A: Pulse dial parameters (addresses 68054A to 68054F) are the values for 10 pps. If 20
pps is used, the machine automatically compensates.
B: The first ring may not be detected until 1 to 2.5 wavelengths after the time specified by
this parameter.
C: The calculated level must be between 0 and 10.
The attenuation levels calculated from RAM data are:
High frequency tone:
