The Summit/Altitech 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 happen. It has been
your experience that the majority of the problems seen by consumers with products such as these are
related to dead or dying batteries.
While the estimated life of a fresh battery in the unit is approximately one year, this can be shortened
considerably if the compass, altimeter or EL systems of the unit are 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. If the battery of the Summit/Altitech is failing it
may show itself in several ways.
Indications of a weak battery are:
1. A fading or blank display.
2. If the display goes blank when the EL system is operated and then comes back on when the EL
system turns off.
3. Inaccurate readings from the Altimeter or Compass systems.
Because the compass is magnetic it may be affected by local sources of electromagnetic radiation
(EMI). Avoid using the compass near appliances, in cars, near home security systems and other sources
of EMI.
The Summit/Altitech is equipped with a display which allows it to be used in a wide variety of
environments. However, if the unit is used in extreme cold (<32 F or 1c) 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 operating levels.
