Once you have set the reference altitude of the current location to the known altitude, the Ob-
server will also correct the sea level pressure, and therefore, it will not be necessary for this
function to be set.

LOGBOOK MODE
Starting and Stopping a Logbook Recording
In the main altimeter mode, a logbook recording starts by performing two short presses of the
[ON OFF] button. An ongoing recording is indicated with flashing LOG text in the bottom
field. To stop a logbook recording, you must be in the altimeter mode and perform two short
presses of the [ON OFF] button again.
The memory capacity is 99 logs, each at maximum 20 hour duration. After recording the 99
th
logbook, the Observer writes the next logbook over the logbook number 1 (the oldest log) and
then continues in numeric order.
The logbook is recording in 10-second intervals, which is quick enough for all activities. It is
not possible to view the individual values of the logbook.
