Timex Watch (T2P277) T2P277 Scheda Tecnica

Before use, the compass must be calibrated.
Since a compass uses the earth’s magnetic field, you 

must be aware of large metallic objects, such as vehicles 

or bridges, or objects that give off electromagnetic 

radiation, such as televisions or computers, which 

could affect the magnetic field around the watch. If the 

compass is calibrated near such objects, it will only 

work properly in that same location. If the compass 

is calibrated away from such objects, it will not work 

properly near them. For best results, calibrate in the area 

of intended use.
In calibrating and taking headings, it is important, as with 

all compasses, to keep the compass level. Calibrating or 

taking a heading when the watch is not level can result 

in large errors. Also avoid areas that may exhibit higher 

than normal concentrations of hard and soft iron, as they 

may cause inaccurate headings. Whenever a heading is 

suspect, recalibrate. 
Do not store the watch near any source of magnetism, 

such as a computer, appliance, or television, as the 

watch can take on a magnetic charge, yielding inaccurate 

headings. Typical accuracy of wrist-worn instruments is 

within +/- 10 degrees.
To calibrate the compass:
1.  Pull the crown to its middle position and wait for the 

indicator hands to stop moving.

2.  keep the watch level or place it on a level surface (if 

the band interferes, place the watch on an inverted 

cup). The watch may be face down, but take care to 

protect the watch face.
