reception is interrupted
GPS reception may be interfered
with in forests, when you are

information can be called up on
the device under “Settings” ->
“GPS Info”.

sources of interference such as
magnets or high-voltage power
lines close by.

calibrated
When there are changes in the
weather or you experience great
gains or losses of altitude, you
should calibrate barometer
several times a day.

calibrate the barometer manually,
by entering an altitude, in
particular before recording a
