section carefully so that you will fully understand how the units and its features work.
The manual is divided into sections outlining each of the major functions of the
instrument. A drawing of the instrument screen that represents the starting point
or other important screen for each operational process is shown adjacent to the
instructions for the process; important keys are shown in color indicating PRESS &
HOLD and PRESS. The steps for the programming or operation are adjacent to the
screen illustration. Key points and important information are shown in highlighted
blocks.
The instrument itself is an important part of this manual as it prompts you through its
operation.
CARE & MAINTENANCE
Your Enduro instrument should be protected from shocks, extreme heat and extended
exposure to direct sunlight. You should only perform service procedures related to the
changing of the battery as shown in this manual. NEVER attempt to disassemble. Store
your instrument in a clean, dry area at room temperature.

REPLACING THE BATTERY
The Enduro instruments use a common CR2032 3v Lithium battery. Normal battery life
is approximately 1yr.
NOTE: Heavy usage of the Compass or Backlight system may significantly
reduce battery life.
NOTE: A blank display or inaccurate compass readings are indications that the
battery is getting weak and should be replaced.
1. Remove the 4 screws using a small phillips-head
screwdriver.
2. Remove battery door.
3. Carefully remove the old battery. Do not damage the O-ring
seal.
4. Place a fresh battery in the battery compartment with the
positive (+) side facing up.
5. If the O-ring has been damaged, replace it before
reinstalling the battery door. Most jewelers and instrument
shops should have replacement O-ring seals.
6. Replace battery door and fasten the 4 screws.
NOTE: Extreme care should be taken when replacing the battery to ensure the
unit remains fully water resistant. Failure to properly replace the battery and
correctly seal the unit may cause the unit to become damaged and may void the
warranty
NOTE: It is recommended that you have the battery replaced by a jeweler or
watch repair shop.
RESETTING THE INSTRUMENT
To reset the instrument back to its default values PRESS the
MODE, SET/CLEAR, START/LAP and STOP/NEXT keys
down at the same time. The display will light up showing all
segments followed by a sequence of screens showing various
numbers. The instrument will then automatically change to the
time of day screen at 12 o’clock on the first of January.
Resetting the instrument will clear any information stored in the
instrument. This should be done only as a last resort.
