IF THE ALTITUDE IS NOT KNOWN, THE USER CAN SET THE SEA LEVEL PRESSURE IN
THE BAROMETRIC MODE (REFER TO PAGE 37, SETTING THE SEA LEVEL PRESSURE).
SETTING THE SEA LEVEL PRESSURE WILL ADJUST THE ALTIMETER TO THE CURRENT
ALTITUDE WITHIN SOME TEN METERS OR FEW HUNDRED FEET.
INFORMATION ON THE CURRENT SEA LEVEL PRESSURE CAN BE OBTAINED THROUGH NEWSPAPERS, LOCAL
NEWS AND RADIO WEATHER REPORTS, THE LOCAL AIRPORT FACILITY OR THROUGH THE INTERNET UNDER
LOCAL WEATHER.
Setting the Altimeter
In setting the Altimeter, there are three processes that can be performed:
the Reference Altitude (known altitude at the current location),
the Altitude Alarm (signifies the user when a certain altitude, programmed, is reached), and
the Logbook Recording Interval (allows the user to view the altitude and average rate of vertical
movement within a chosen interval of time).
To begin:
1. PRESS the [Select] button and hold for 2 seconds. Located in Field 1 is the text RE (indicating reference
altitude), located in Field 2, the current altitude will begin to flash.
2. PRESS the [+] button to scroll the altitude upward or
PRESS the [-] button to scroll the altitude downwards.
3. At the desired reference altitude, either PRESS the [Mode] button to accept the changes and return to
the main mode or PRESS the [Select] button to move to the next setting. Located in Field 1, the ON
or OFF will begin to flash.
4. PRESS either the [+] or the [-] button to toggle between the ON and OFF for the Altitude Alarm.
5. At the desired setting, PRESS the [Select] button to move to the next setting. Located in the center of
Field 2, the alarm altitude will begin to flash.
6. PRESS the [+] button to scroll the altitude upward or
PRESS the [-] button to scroll the altitude downwards.
7. At the desired altitude, either PRESS the [Mode] button to accept the changes and return to the
main mode or PRESS the [Select] button to move to the next setting. Located in Field 1, the text INT
and located in Field 2 the time interval will begin to flash.
