6. Resetting the unit
(for EL-1607P (ACO))
Strong impacts, exposure to electrical fields, or other unusual condi-
tions 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.
Note:
• 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 dis-
played.
