The Observer has four main modes: TIME, ALTIMETER, BAROMETER, and COMPASS.
In each of the features there are associated sub modes providing further enhancements to
its usefulness during your outdoor adventures. All key features and sub features will be
discussed in further detail following this chapter.

1.5 BACKLIGHT FEATURES

The Observer has an electroluminescent backlight. To activate the backlight, press and hold
the [MODE] button for 2 seconds. The backlight will remain on for approximately 10 seconds. If
you press buttons to operate, the backlight remains on 10 seconds from the last pressing.

1.6 WATER RESISTANCE

The Observer is water resistant up to 100m/330ft. However, it is not a diving instrument and
therefore the buttons should not be operated (put in use) while underwater.

and [SELECT].
The MODE Button
Located on the top right of the Observer performs the following functions:
• A short press allows you to move from one mode to the next (TIME, ALTI, BARO, COMP).
• While in the sub mode level, a short press returns you to the main mode.
• During the setup process, a short press accepts all changes and exits the set function.
