Unplug the base unit
hold the page button and plug back in , keep hold of the page button until you hear 6 beeps.Now unplug the unit and plug back in without holding the page button. Now move onto the handset .
Remove one battery and replace it whilst holding down the menu button until you hear a beep, the screen will say TEST MODE,now press number 5 then menu, the screen now shows CLEARED, remove one battery then replace without holding any buttons the display will say NOT REG.
Now press page button on the base unit until 2 beeps are heard .
Press menu on the handset and it will say REGISTER, press menu and then scroll down to REG BASE, the screen says SELECT BASE 1234 press 1 .
the screen says SEARCH 1 wait and it will ask for PIN enter 0000 and press menu.
This will reset the base unit and the hanset now you can repeat the handset process to reset all other handsets. all handsets are set to base 1 .
Hope this helps
