Clearing Period Information/Starting a New Period
Beginning a new period clears all data from the previous period. The system
stores the beginning date of the period, which you may display along with the
number of days which have elapsed since the beginning of the period. A new
total UV radiation dose begins to accumulate and the Health EM begins to cal-
culate a new average daily UV radiation dose. To clear period information and
begin a new period you may clear total UV dose as described in “Clearing
Daily and Total UV Dose” on page 23 or as described below.
Note:
The system records the start time of the period to the nearest 90 minutes. Therefore, all average val-
ues are exact to the nearest 90-minute mark throughout the period. However, averages calculated
during the period are most accurate when the period length is an exact number of days (that is, if
you display the average at the same time of day at which the period started). When the length of the
period is displayed, the GroWeather rounds down to the nearest whole day COMPLETED.
1. Press UV as necessary to display the period information.
2. Press and hold down CLEAR.
As you hold down CLEAR, the display alternates between showing the
number of days in the period and the word
A L L
and showing zeros
(
0 0 0 0
) on both sides of the display. This provides you ample warning that
the Health EM is preparing to clear the period information and begin a new
period.

3. To clear the UV period totals and begin a new period, hold down CLEAR until the dis-
play stops flashing and the period information display returns to normal.
When the display stops flashing, it means that the Health EM has cleared
the UV period totals and begun a new UV period.
Alarms
You may set a high alarm for current UV radiation intensity and “daily” UV
radiation dose. (See “Alarms” on page 42.)
