Does the screen work when the Parent Unit is placed inside the Charging Cradle? If yes, please change the rechargeable batteries?
We recommend that the batteries are replaced approx. every 6 months as the cells depreciate over a period of time and despite showing as fully charged this can be false. It could also cause the screen not to display correctly.
If however the screen does not display fully when placed inside the charging cradle it will be that the screen is failing on the Parent Unit.
