POWER SOURCE
Insert the AC plug (with the 2 blades) into a conveniently located AC outlet having 110V-
120V~60Hz.
NOTE: The AC plug supplied with the unit is polarized to help
minimize the possibility of electric shock. If the AC plug does
not fit into a nonpolarized AC outlet, do not file or cut the wide
blade. It is the user’s responsibility to have an electrician
replace the obsolete outlet.
MAIN POWER SUPPLY
• Check that the power voltage as shown on the type plate corresponds to your local power
voltage. If it does not, consult your dealer or service organization.
• Connect the power cord to the wall outlet of AC power supply. As soon as you insert the
power plug into the wall outlet, the display time will flash and show (Assuming there
is no battery for backup or battery is weak). Please see page E13 how to set the correct
time.
POWER FAILURE
If power failure occurs, the unit will switch off. As soon as the power supply returns, will
flash and display, indicating that you must reset the correct time.
BATTERY BACK-UP SYSTEM
• Insert 2 “AA” batteries (not included) into the battery compartment. In the event of a power
failure, the batteries will provide sufficient power to maintain the time. W hen AC power is
restored, the correct time will be restored and will not require resetting.
• Neither the display nor the unit will operate until the unit is connected to an AC outlet.
BATTERY WILL ONLY RESTORE CLOCK SETTINGS WHEN AC POWER IS RESTORED.
• Replace the battery once per year. The service of the battery depends on how often and for
how long the power supply fails. This varies from one region to another.
Note:
1. Always check the time and reset if necessary when first time connecting AC mains or after
a power failure.
2. The 2 batteries are used for backing up the time in case of AC mains power failure, under this
circumstance, do not attempt to operate the unit, otherwise, battery service life will be
reduced.
