HOW TO INSTALL
BATTERIES
Following
the safety instructions set forth below under “SAFETY INSTRUCTIONS”, an adult
should:
1. Push
open the loosely-hinged
battery compartment door after carefully loosening its screw with a
screwdriver. Neither the door nor the screw should be removed entirely.
2. Install
2 new AA-size 1.5-volt alkaline batteries with correct polarity (+,-)
following the illustration inside the battery compartment.
3. Close
the compartment door and tighten the screw.
Note: Installing
batteries "resets" the FlashMaster—restoring all its original
settings and erasing its temporary memory, including all stored results and
missed or “entered” problems.
SAFETY
INSTRUCTIONS AND MAINTENANCE
·
IF EARPHONES (not included) ARE
USED, BE SURE THEY ARE NOT TOO LOUD.
· ONLY
ADULTS SHOULD REMOVE OR INSTALL BATTERIES.
· If a battery is
swallowed, call a doctor immediately.
· Batteries
should be kept away from children who still might put things in their
mouths.
· Use only
1.5-volt alkaline AA-size batteries—2 of them.
· Install
batteries with correct polarity—that is, with the "+" and/or
"-" on both batteries aligned with the "+" and/or
"-" markings in the battery compartment.
· Use only
batteries of the same type.
· Do not mix old
and new batteries.
· Do not mix
alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium)
batteries.
· Do not use
rechargeable batteries.
· Do not try to
recharge non-rechargeable batteries.
· The supply
terminals must not be short-circuited.
· Remove
exhausted or corroded batteries.
· Dispose of old
batteries lawfully and promptly.
· Remove
batteries to prevent corrosion if the FlashMaster will not be used for at
least 2 weeks.
· Do not expose
batteries to fire or heat since batteries may explode or leak corrosive or
toxic material, etc.
MORE MAINTENANCE INSTRUCTIONS
·
Use common sense to protect the Flashmaster and children.
·
Handle the FlashMaster gently and carefully.
·
Do not drop the FlashMaster.
·
When the FlashMaster is carried in a backpack,
it should be located, cushioned, and/or wrapped in order to protect
it—especially its display (“LCD”) and keys.
·
Keep the FlashMaster dry. If it gets wet, dry it immediately.
·
Do not expose it to severe cold or high heat. For example, do not leave
it on the dashboard of a car.
·
Wipe it with a damp cloth to clean it. Do not use cleaning solvents or
strong detergents or chemicals.
·
If “REPLACE BATTERIES” blinks, new ones are needed.
