What to do if my Grundig Cordless Telephone has no display?

First, check if the batteries are fully charged, and try replacing them. Ensure the batteries are properly installed and connected. If using AC power, verify the unit is connected to a non-switched electrical outlet, and try disconnecting and reconnecting it. Also, confirm that you have Caller ID service from your local telephone company.
