with your house electricity supply which must be A.C. (Alternating current).

If the socket outlets in your home are not suitable for the plug supplied
with this appliance the plug should be removed and the appropriate one
fitted.
IMP0RTANT : THE PLUG REMOVED FROM THE MAINS LEAD, IF SEVERED,

Battery back-up facility (unit will work without batteries being fitted)
Your alarm clock is equipped with a battery back-up facility.

Should a power interruption occur the clock will continue to run, however, time
keeping will not be accurate. The display will be extinguished to conserve battery
life but the memory will retain details of the clock time and alarm settings.
If the optional battery is not installed in case of the AC power failure when power is
restored, the clock will go through the automatic msf clock setting. You will need to
set the alarm.
Battery back-up is designed to operate for a short period only.
If the unit is not to be used for a prolonged period, remove the battery to
avoid battery leakage.
In the interests of environmental safety : dispose of batteries safely.
