Field 2 displays the current altitude in increments of 5 meters or 10 feet (depending on the unit of measure
selected); and
Field 3 displays the current time or the current heart rate if the transmitter is worn.
The Outer Circumference graphically displays the altitude in hundreds of meters or feet over a full thousand
where one complete circle is equivalent to 1000.
Note: In order for the HRM feature to be activated the user must be wearing the transmitter belt around his/her
chest. The HRM indicator in the lower right section of the LCD flashes according to the measured heart rate
(beats/minute). Refer to Section 2 Heart Rate Monitor for details in setting and activiting this feature.
When wearing the belt, the current time can be viewed for 10 seconds by pressing the [+] button. If the belt is
not worn, the current time is shown on the bottom row (Field 3), in place of the heart rate.
IMPORTANT NOTE: In order to set the altitude in the Altimeter mode, the altitude must be known. That information
can be found by utilizing a topographical map identifying the current location with the associated altitude marked.
The user can then proceed and follow the instructions, setting the altimeter, provided in the section below.
DETAILS REGARDING THE EFFECT OF AIR TEMPERATURE ON ALTITUDE MEASUREMENT ARE SHOWN
ON PAGE 50 OF THIS MANUAL.
IF THE ALTITUDE IS NOT KNOWN, THE USER CAN SET THE SEA LEVEL PRESSURE IN THE
BAROMETER MODE (refer to page 39, Setting the Sea Level Pressure).
SETTING THE SEA LEVEL PRESSURE WILL ADJUST THE ALTIMETER TO THE CURRENT ALTITUDE
WITHIN APPROXIMATELY TEN METERS OR 30 ft. A 1-mbar CHANGE RESULTS APPROXIMATELY AN 8-
METER (OR 26 ft) CHANGE IN ALTITUDE, AND A 0,05 inHG CHANGE RESULTS A 45 ft. CHANGE IN
ALTITUDE.
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.
