Fail-safe timer
The fail-safe timer allows the user to vary the 'waiting' period from the time a loss of echo or
operating fault condition begins, until the fail-safe default is effected. The 'waiting' period is
adjustable from 1 to 15 minutes, in 1 minute increments.
The fail-safe timer value will default to settings determined by the Speed of response
(Page 27). If a different value is desired, the fail-safe timer should be adjusted after the speed
of response is set.
