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.
