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 30).
If a different value is desired, the fail-safe timer should be adjusted
after the speed of response
is set.

and proceed as follows:
1.
Press the "20" key to increase the 'waiting' period, and press the "4" key to decrease it.
2.
Once you have reached the appropriate value, stop pressing the key. The display
automatically returns to the Run mode (6 secs).
