CONVENIENT OPERATION OF THE UNIT
< How to read the battery indicator > ● When the battery is completely discharged,
the battery indicator will flash. Recharge the battery or replace the alkaline battery with a new one.
● When the battery has run completely out,
“BATT EMPTY” will appear. Then, the power will be disconnected automatically.
Notes: ● If you use the battery which you stopped
charging halfway, “
” may appear. It
does not mean that the battery is com- pletely charged.
● When using the unit with an alkaline bat-
tery or a rechargeable battery, the battery indicator will not correctly display the remain- ing capacity for approximately 10 seconds after the power has been turned on.
● When the AC adaptor included with this unit
or a separately available car adaptor is used, the battery indicator will not be shown.
● The number of bars shown in the battery
indicator may increase or decrease, de- pending on the operation being performed. This is normal.
■ To prevent the unit from being
operated by mistake
To avoid accidental operation of the unit, use the hold function. Move the HOLD switch to the safety posi- tion (direction indicated by the arrow). ● When the unit is in the hold mode, press-
ing the buttons will have no affect.
● To cancel the hold mode, move the
HOLD switch away from the safety po- sition (the opposite direction of the ar- row).
