For Interdigit Timer Master Override, enter S0 to reduce the short inter-digit timer to 0 seconds, or enter L0 to reduce the long inter-digit timer to 0 seconds. To pause, enter P, the number of seconds to pause, and a space. This feature is typically used for implementation of a hot line and warm line, with a 0 delay for the hot line and a non-zero delay for a warm line.
