6. PRECAUTIONS BEFORE USE
1 Occasionally make sure that the
power plug is not abnormally hot.
If the power plug is abnormally hot, contact
your nearest dealer.
2 Make sure that the power cord is not
frayed nor scratched.
3 Connect the power plug to the
electrical outlet properly upon use.
4 When not using the unit over a long
period of time, turn on its power
occasionally.
The unit has a built-in battery to protect the different
types of data registered.
• The battery is used when the power of the unit is
off. (It will be used even if there is nothing
registered.) It is charged when the power is on.
• As the data registered and set will be lost when the
battery has worn out, be sure to keep a copy of it.
• The battery will wear out when the unit has been
left off continuously for about three months. Turn
on the power occasionally to charge it.
