For alarm clocks with fitted plug.

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, MUST BE DESTROYED AS A PLUG WITH A BARED FLEXIBLE CORD IS HAZARDOUS IF ENGAGED INTO A LIVE SOCKET OUTLET.

Should the fuse in the 13 amp mains plug require changing a 3 amp BS1362 fuse must be fitted.

The socket outlet should be installed near the equipment and shall be easily accessible.

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

2Insert 3 x AA size 1.5V batteries and connect to terminals (Ensure the batteries are inserted correctly).

3Replace the battery compartment cover. (Batteries not supplied).

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.
