Note:
Selectors 1 through 3 are applicable only to models equipped with built-in TADs.
Selector 8 is applicable only to models equipped with V34.
• Selectors 1 through 3: Prevention of line interrupt during ICM recording (ratio of guard
tone response time to call end tone ON time) (Not used.)
If an ICM tone is detected as a call end tone by error, this machine will release the line even
during ICM recording. To avoid this problem, change the setting for the ratio of guard tone
response time to the call end tone ON detection time.
If the actual percentage of guard tone response time is greater than the percentage set by
selectors 1 through 3, this machine will judge that the call end tone has not yet been
detected and will continue ICM recording.
