CHAPTER 1 INTRODUCTION
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.

1.3 ADJUSTING THE BRACELET (ST AND
TT MODELS)
The metal / elastomer bracelets of the Observer
models St and Tt have to be adjusted for the user.
The steps are
1. Remove the buckle by releasing the spring bars
with pin, paper clip or other sharp object.
2. Remove both spring bars from the pin holes.
3. Shorten the bracelet by cutting along the grooves
on the inner surface of the bracelet. You can do
this for instance with scissors. If you are unsure
of the correct length, cut the pieces one by one
and test the length after cutting each piece. Cut
in turns from both sides of the bracelet to keep
the sides equally long. Be careful in order not to
shorten the bracelet too much.
4. Replace the spring bars into the last pin holes of
both sides of the bracelet.
5. Attach the buckle to the bracelet by placing the
spring bars into the holes in the buckle. In both
sides of the buckle are holes for two different
positions. This can be used for fine adjusting of
the bracelet length. Make sure that the spring
bars are positioned straight in the buckle.
