1. Introduction
Thank you for buying the Trelock Geo Coach.
This watch has electronic sensors that
measure and display the outside conditions:
altitude, temperature, air pressure and
compass. The watch shows you all important
information - as well as a weather forecast
- you will need when hiking, camping or other
outdoor activities over a longer period of time.
Important notes
For the best reading of the
temperature, remove the watch from
your
wrist and wait for approximately 15 to 30
minutes. For more
information see the expla-
nation of the thermometer on page 58.
For correct use of the altimeter, adjust it as
often as possible. For
more information see
the explanation of the altimeter on page 58.
