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.
0.20 (0.008) Maximum Ref.
Permissible deflection from a flat.
0.10 (0.004) Minimum Ref.
(Applies to top edge of gasket or
edge of crimp, whichever is higher.)
(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.
