Automatic Shutdown
The OtoRead instrument has an automatic “shutdown” feature,
designed to prolong battery life. The unit will automatically
shut down after 1 minute (default) of inactivity. To turn it back
on, simply press the DOWN Key. This feature can be re-
programmed for various periods of inactivity before
“shutdown.” (See the Changing Instrument Settings – Auto-
Shutdown Time section on page 29 for further information on
this feature.)
