Before using this unit, carefully read the sections entitled:
"USING THE UNIT SAFELY" and "IMPORTANT NOTES"
(supplied on a separate sheet). These sections provide
important information concerning the proper operation
of the unit.
Additionally, in order to feel assured that you have gained
a good grasp of every feature provided by your new unit,
this manual should be read in its entirety. The manual
should be saved and kept on hand as a convenient
reference.
A battery was installed in the unit before it left the factory.
The life of this battery may be limited, however, since its
primary purpose was to enable testing.
