STEP 1: UNSCREW THE HOUSING 

The housing is red or green depending on the model. Turn the power switch off and use a small Phillip’s Head screwdriver to remove the two screws that secure the outer housing to the inner body. Remove the screws.

STEP 2: REMOVE THE HOUSING

Gently pull the outer housing away from the inner body and place the inner body on a flat surface with the lasers and exposed electronics facing up towards you. 

STEP 3: INSERT TWO LR44 OR 357 COIN CELL BATTERIES

Carefully insert two new LR44 or 357 coin cell batteries into the two battery slots. The negative side of the battery (which is the curved cap) should be oriented so it is facing down when inserted into the battery slots against the battery coils on the printed circuit board. 

STEP 4: REPLACE THE HOUSING 

Verify that the batteries are oriented and installed correctly. Orient the housing so that the optical window in the housing is positioned over the laser and optics in the inner body. Gently slide the housing onto the inner body.

STEP 5: SECURE THE HOUSING

Carefully turn the entire assembled unit over so the switch side of BullseyeBore Core is visible. Use a small Phillip’s Head screwdriver to replace the two screws that secure the outer housing to the inner body. Do not overtighten the screws. 

STEP 6: TURN THE POWER ON

Test the battery installation by turning on the power switch and verifying that the laser illuminates and projects two beams for models CR1-100 and CG1-100 and three beams for models CR1-101 and CG1-101.
