IMPORTANT SAFETY
INSTRUCTIONS:
SAVE THESE INSTRUCTIONS
Be sure to observe the following important
precautions whenever using the charger and
adapter. Never try to open the case of the
charger or attempt your own repairs. Highvoltage internal components present the risk of
electric shock when exposed.
Keep the charger and adapter away from
water and other liquids. Never let them
get wet. Moisture can cause fire and
electric shock.
Should you ever notice smoke or a
strange odor coming out of the charger,
immediately unplug the AC adapter
from the power outlet. Using the charger
under these conditions can cause fire and
electric shock.
Unplug the AC adapter from the power
outlet and clean the area around the
prongs of the plug when necessary. Dust
around the prongs can cause fire.
Safety Instructions | 11
AC ADAPTER PRECAUTIONS
Never use an electrical outlet whose
voltage is outside the rating marked on
the AC adapter. Doing so can cause fire
or electic shock. Use only the supplied AC
adapter or DC car cord (optional) for the
charger.
Do not allow the AC adapter power
cord to be cut or damaged, and do not
place heavy objects on it. A damaged AC
adapter cord can cause fire or electric
shock.
Never try to modify the AC adapter
power cord, or subject it to severe
bending, twisting, or pulling. Doing so can
cause the risk of fire and electric shock.
Never touch the AC adapter while your
hands are wet. Doing so can cause electric
shock.
Do not overload extension cords or wall
outlets. Doing so can cause fire and
electric shock.
12 | Safety Instructions
Indoor use only. Do not expose the
charger to rain or snow.
To reduce the risk of damage to the
electrical plug and cord, disconnect by
pulling the plug, not the cord.
Make sure the cord is located properly
so that it will not be stepped on, tripped
over, or subjected to damage.
To reduce the risk of electric shock,
unplug the charger from the outlet before
attempting cleaning, or when not in use.
Do not use solvents to clean the unit.
They may damage the surface and the
plastic parts of the unit. Clean the unit
gently with soft dry cloth only.
Not recommended for use by children.
BATTERY HANDLING PRECAUTIONS
Incorrect handling or misuse of bateries can
cause them to leak or burst and damage your
charger. Be sure to note the following important
precautions to avoid problems with batteries.
Use only Ni-MH or Ni-Cd dry cell batteries
with the charger. Do not charge any other
Safety Instructions | 13
kind of batteries, as they may burst and
cause personal injury and damage.
Always make sure that the plus (+) and
minus (-) terminals of the batteries are
facing correctly, corresponding to the
markings on the charger itself. Improper
loading of batteries creates the danger
of personal injury or damaging objects
nearby.
Do not expose batteries to direct heat or
dispose of them by burning. Doing so can
cause an explosion.
Do not operate the charger in an
environment with temperatures over
40°C (104°F) due to the risk of electrolyte
leakage, over-heating, and battery
damage.
The batteries that power the equipment
normally become warm as they discharge.
If electrolyte material touches your eyes,
immediately wash eyes with running cold
water, and get medical attention.
Please recycle the dead batteries, and
preserve our environment.
