■ The power unit is equipped with a 3 wire grounding type plug; a plug
having a third (grounding) pin. This plug will only fit into a grounding type
power outlet. This is a safety feature. If you are unable to insert the plug
into the outlet, contact an electrician to replace the outlet. Do not defeat
the safety purpose of the grounding type plug.
■ Do not allow anything to rest on or spill into the products.
■ To reduce risk of fire and electrical shock, do not overload power outlets.
■ Never push objects of any kind through the power supply or distribution
unit slots as they may touch dangerous voltage points or short out parts
that could result in a risk of fire or electrical shock.
■ To reduce risk of electric shock, do not disassemble these products.
Return them for repair when needed. Opening or removing covers may
expose you to dangerous voltages or other risks. Incorrect reassembly
can cause electric shock when the products are subsequently used.
■ Power down the power unit (see label on power unit on how to do this) and
refer servicing under the following conditions:
— If liquid has been spilled into any of the products.
— If any of the products have been exposed to water.
— If any of the products do not operate normally.
— If any of the products have been dropped or damaged.
— If any of the products exhibits a change in performance.
■ Do not attempt to recharge batteries on your own. The batteries may leak
corrosive electrolyte or explode. The 1145B power unit recharges the
batteries safely.
■ Remove the batteries if the power unit will not be used for a long period of
time (several months or more) since during this time the battery may leak.
■ Discard discharged batteries as soon as possible. Discharged batteries
are more likely to leak.
■ Do not store batteries in high temperature areas. Batteries stored in a cold
environment should be protected from condensation during storage and
warming. Batteries should be stabilized at room temperature prior to use
after cold storage. Do not install batteries if the manufacturing date on the
label indicates that the batteries are more than 6 months old.
