Safety:
(1) KEEP OUT OF REACH OF CHILDREN. Swallowing may lead to
serious injury or death in as little as 2 hours due to chemical burns and
potential perforation of the esophagus. Immediately see doctor;
have doctor phone (800) 498-8666.
(2) Battery compartment design. To prevent children from
removing batteries, battery compartments should be designed with one
of the following methods: a) a tool such as screwdriver or coin is
required to open battery compartment or b) the battery compartment
door/cover requires the application of a minimum of two independent
and simultaneous movements of the securing mechanism to open by
hand. Screws should remain captive with the battery door or cover.
