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.
