is normally indicated on maps. The diff erence is called declination, and
it can vary depending on where on Earth you happen to be standing. For
example, in the United States, declination can vary from approximately
15 degrees East on the West Coast to 15 degrees West on the East
Coast.
• Location
Taking a compass reading when you are near a source of strong mag-
netism can cause errors in readings. Because of this, you should avoid
taking compass readings while in the vicinity of the following types of
objects: permanent magnets (magnetic necklaces, etc.), concentra-
tions of metal (metal doors, lockers, etc.), high tension wires, aerial
wires, household appliances (TVs, personal computers, washing ma-
chines, freezers, etc.).
Accurate readings are also impossible while in a train, boat, airplane,
etc., and while indoors – especially inside ferro-concrete structures.
• Storage
The accuracy of the bearing sensor may deteriorate if your Z1 becomes
magnetized. Because of this, you should store your Z1 away from
magnets or other sources of strong magnetism, including: permanent
magnets (magnetic necklaces, etc.) and household appliances (TVs,
personal computers, washing machines, freezers, etc.).
If you suspect that your Z1 has become magnetized, try recalibrating
the compass. If problems persist, take your Z1 to your authorized
SCUBAPRO dealer.

Behavior While in Compass Mode
•
The Auto Light function will not illuminate for 60 seconds during
calibration.
•
If an alarm sounds during calibration or when the light is activated
by pressing the LED/LOG button, calibration will be temporarily
suspended and calibration will resume after the alarm is stopped or
after the light is turned off .
•
Atmospheric pressure and temperature will be measured up to
every 20 seconds because the compass direction reading is priori-
tized.
