@Gajo 

Try 0000.  4 zeros.

Default PIN is 0000.

Although I'm surprised you were able to factory reset without it. Did you reset base & handset?

Manual

[Gajo]

four zeros 0000 has been tried but does not match, still states incorrect pin

[Gajo]

the handset is not connected to base as it was in use elsewhere, another user had it and does not know the pin, and wasnt aware it had a pin set.

Reset the handset page 63 in manual.

Reset the handset or base settings ....63 or page 64

Will this work on a handset that has come from another base unit?

Thanks

@Gajo It sounds like the pin has been changed from the default 0000 on the base. You need a handset that is registered to the base in order to reset it.
