c. Remove a new battery from the plastic bag, place the new
battery in the battery compartment (if a battery is already in
place, remove the existing battery).
d. Pay careful attention to the battery polarity marks inside the
battery compartment (plus sign on the neck strap side, minus
sign on the sensor lead wire side). The sensor should beep
once within 10 seconds of placing a new battery. If no sound is
heard after ten seconds, verify that the battery has been
placed in the correct position. If the position is correct, try
another battery. If the second battery fails, contact LifeWatch.
