TROUBLE SHOOTING BASIC

Your Enduro instrument is a very sensitive and sophisticated instrument. If properly
cared for it should last and remain accurate for many years. However, from time to time
problems may occur. It has been our experience that the majority of the problems seen
by consumers with products such as the Enduro are related to dead or dying batteries.
While the estimated life of a fresh battery in the unit is approximately 1 year, this
can be shortened considerably if the backlight feature of the unit is used extensively.
Whenever you are experiencing issues related to the function of the unit, it is
recommended that you install a fresh battery as a first course of action, especially if it
has been more than a half a year since the last time the battery was replaced.
BE AWARE: Lithium batteries of the type used in this instrument are very susceptible
to improper storage. Many times, batteries purchased as new are dead or weak before
they are purchased. Do not assume that batteries in stores are good. If you try a new
battery and problems persist, please try a second battery from another source, just to
be certain.

TROUBLE SHOOTING BASIC
If the battery on the instrument is failing it may show itself in several ways. Indications
of a weak battery are:
A fading or blank display. Also if the display goes blank when the backlight is operated
and then comes back on when the backlight system turns off.
Inaccurate readings from the compass.
If the display goes blank when the EL system is operated and then comes back on when
the EL system turns off.
The display of your instrument may "freeze" due to static electricity or battery
replacement. If this occurs, remove the battery and re-insert it. This will erase the data
in the memory and reset the instrument to factory settings.
Enduro instruments are equipped with a display which allow them to be used in a wide
variety of environments. However, if the unit is used in extreme cold (<32°F or 1°C) the
function of the display may be slower than normal. If exposed to extreme heat or cold,
the display may also darken. The display should return to normal once the temperature
returns to normal levels.
Because the compass is magnetic it may be affected by local sources of electro-
magnetic radiation (EMI). Avoid using the compass near appliances, in cars, near home
security systems and other sources of EMI.
