When all the memory places are filled, the logbook starts recording new logs on top of the oldest recordings.
This is what is meant when we say the logbook is “self-erasing”.
You can clear the history of the logbook; i.e. where you get the cumulative ascent and descent information
based on the logs recorded into the logbook.
The number of logs you can record into the logbook depends on the chosen interval and the length of each log.
For example, if your interval is 1 minute, you can get a total of 1,900 minutes of logs into the logbook. This
equals 1.32 days if the recording is continuous (24 hours = 1,440 minutes; 1,900/1,440=1,32).
To avoid excessive battery drain, the recording is not continuous. The recording functions have certain timeouts
(i.e. the recording will be turned off automatically after a certain time). The timeouts are shorter for the shorter
interval and longer for the longer interval.
The duration readout tells you how many hours and/or minutes the event recorded into the logbook lasted. For
example, if you’re hiking from 1 p.m. to 6 p.m. and the logbook is on during this time, the readout would show
a duration of 05:00 hours.
The maximum figure that can be shown on the display is 29,999,999 representing feet or meters depending on
the unit of measurement set. This should be enough for most users: 29,999,999 meters is roughly three-
quarters around the globe.
There are several answers to this question related to different situations.
