1.1 GENERAL INFORMATION
The Observer Wristop Computer is a reliable high precision electronic instrument, intended
for recreational use. The outdoor enthusiast who enjoys venturing in sports like skiing,
kayaking, mountain climbing, hiking and biking can rely on the Observer’s accuracy.
NOTE:
The Observer should not be substituted for acquiring measurements that require
professional or industrial precision and should not be used to acquire measurements when
skydiving, hang gliding, paragliding, gyrocopter riding and flying small aircraft.
The Observer is available in three different material combinations:
Observer Sr with stainless steel housing and elastomer strap, Observer St with stainless
steel housing and stainless steel / elastomer bracelet and Observer Tt with Titanium housing
and Titanium / elastomer bracelets. All material versions have identical functions and
operation.
1.2 CARE AND MAINTENANCE
Perform only the procedures discussed in this manual.
Never attempt to disassemble or service the Observer.
Protect your Observer from shocks, extreme heat and prolonged exposure to direct sunlight.
If not in use, your Observer should be stored in a clean, dry environment at room temperature.
The Observer can be wiped clean with a lightly moistened (warm water) cloth. Applying a
mild soap to the area can clean stubborn stains or marks.
Avoid exposing the Observer to strong chemicals like gasoline, cleaning solvents, acetone,
alcohol, insect repellents, adhesives, and paint, as they will damage the unit’s seals, case
and finish.
Make sure the area around the sensors (located on the right of the instrument) is kept free of
dirt and sand. Never insert any objects into the sensor openings.
