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 (202) 625-3333.
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.
