Welch Allyn OAE Hearing Screener - User Manual - Manual (Page 22)

Clock settings
Set the date and time before using the screener. The clock should be set prior to testing
because changing the date and time after tests are saved will not change the date on the
printout.
Seasonal time changes, such as Daylight Saving Time, also require resetting the clock.
Note If the screener is being powered on for the first time or if the battery is
completely discharged and is not charged within approximately one hour,
an Error! Reference source not found may appear. If this message
appears, reset the date and time.
