Is the base to your phone on? That’ll make your phone think it is out of range. Next, make sure the phone is placed in the base for at least 5 minutes to reset its connection to the base, and then try placing a call after. If the problem still persists, there could be other signals messing up the connection. Check to see if there are any other cordless phones or ham radios around, and try turning them off. After that your phone should be able to connect.
Make sure the ringer is not turned off. Then, check the phone line cord and power cord to see if they are securely plugged into the base and the wall. Also, check to see if the cordless handset is not too far away to ring. And don’t forget to keep charging the battery even when you aren’t actively using it.
First, make sure that the power can get to the phone. Try unplugging everything, wait a minute then plug it all back in. Next, try checking the battery. If the battery is defective, that will cause issues with the charge light. If that doesn’t work, then maybe there is dirt or dust in the charger for the handset. If there is, then wipe it off and then try connecting the phone.
