IF THE ALTITUDE IS NOT KNOWN, THE USER CAN SET THE SEA LEVEL PRESSURE IN THE BAROMETRIC
MODE (REFER TO PAGE 31, 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.
3.1 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 rate of vertical movement within a
chosen interval of time).
To begin:
1. PRESS the [Select] button and hold in 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 (Fig. 2).
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 (Fig. 3).
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.
