Refer to fig 12a to set the sea level pressure. Repeat this procedure
after changing the battery or after one year of operation.
BAROMETRIC HISTORY
Your unit retains the hourly barometric pressure for the past 24
hours. Refer to fig 12b to recall the reading for a certain hour.
WEATHER FORECAST
Apart from determining the altitude, the barometer also helps forecast
the weather for the forthcoming 12 to 24 hours basing on barometric
pressure changes. The effective range is 30 to 50 km.
The forecast will be automatically displayed in one of these four
icons:

RATE OF CHANGE IN ALTITUDE
You may monitor the actual rate of change in altitude during your
trip. The maximum ascending speed as well as the descending speed
will be recorded automatically. You may recall and erase this
memory record (fig 11).
Note:
please refer to Section 7 for overall erase memory record.
SECTION 4 THE BAROMETER
This section applies to all models.
There are two display modes in BAROMETER:
• Sea pressure and clock
• Sea pressure and temperature
Refer to Fig 12 to change among the display mode.
HOW TO SET THE SEA LEVEL
PRESSURE
When you first use the OUTBREAKER, please calibrate the sea
level pressure. It will not be altered due to the change in the altitude
but with regard to the barometric change only.
You can obtain the current sea level pressure from newspaper, local
news and radio weather reports or through the internet weather
station.
