INSTALLATION
Note: Mains power is required to power the multifunction features of the telephone. Fit 4 x AA sized batteries in order to save and use stored numbers in case of mains power failure. Without mains or battery power, the telephone can still be used to answer calls or to manually dial out calls but all the multifunction features will not
be available. If no batteries are inserted, the low battery icon 
will be displayed on the LCD display.
