RESETTING THE UNIT

Strong impacts, exposure to electrical fields, or other

unusual conditions may render the unit inoperative,

and pressing the keys will have no effect. If this

occurs, you will have to press the RESET switch on

the bottom of the unit. The RESET switch should

be pressed only when:

• an abnormal event occurs and all keys are

disabled.

• you install or replace the battery.

Notes:

• Pressing the RESET switch will clear the stored

tax / discount rate and conversion rate, other data

stored in the memory.

• Use only a ballpoint pen to press the RESET

switch. Do not use anything breakable or anything

with a sharp tip, such as a needle.

• After pressing the RESET switch, connect the

power supply plug to an outlet. Turn the power

switch "ON" and check that "0." is displayed.
