Remove the batteries by pulling the positive side first straight out of the
battery compartment. Note the positive (+) and negative (-) battery polarity
markings at the bottom of the compartment, as shown below.
Install the three batteries by sliding them into the bottom of the battery slots,
making sure the polarity markings on the batteries align with the markings
shown in the battery compartment. The battery compartment has stand-offs
molded into the side of the compartment. When a battery is installed with the
polarity reversed, the stand-offs prevent the negative battery terminal from
contacting the positive terminal in the battery compartment. The unit will not
power up when a battery is installed this way. Should this happen, simply
reverse the battery to correct the polarity.
With the batteries secured in the battery compartment, replace the
compartment cover. The cover has only one orientation for correct alignment.
The “WARNING
DO NOT OPEN IN EXPLOSIVE ATMOSPHERE ” statement on the
battery cover must be visible and aligned in the approximate middle of the M1
case. To secure the cover, torque the screws clockwise to 1.6 in-lbs. Do not
over tighten.
