Resetting The Unit - Sharp EL-2910R Manual De Manejo

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 rate and 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.
