My phone keeps saying handset out of range. it will not ring or anything its a house phone.

Owner's manual.

This could be due to the fact that one of your phones is off the hook or unplugged. Check and make sure that all devices are operational and charged.. Don't forget to check the phone line itseft.
Cheers

1. Press & hold End and # at the same time until you see the System Reset menu.

2. If you still have the base the handset is registered to, select Deregister HS, then select the handset you want to reset. If you don't have that base anymore, select Base Unavailable.

3. To confirm, select Yes. The handset displays "Handset not registered"


Now you want to register the phone again.

1. Place the handset in the base; the display should say Handset
Registering.

2. Wait until the display says Registration Complete (about 30
seconds), then pick up the handset and press Talk/flash.
You should now have a dial tone

must be sure handset ringer volume is NOT set TO off
2) THE Telephone line cord and power adapter are plugged in properly.
3)the handset may be too far from the telephone base. Move it close to the telephone base.
4) many extension phone on the telephone line to allow all of them to ring simultaneously.
5) if other telephones in your home are having the same problem , the problem will e in service provider
6) other electronic products such as HAM radio detect the phones cause interferences.
7)test a working phone at the wall jack.
8)remove and install the battery again and place the handset in the telephone base
9) wait for the handset to synchronize.
God bless you

You must register the orphan handset to the base you are keeping.

Check the phone to ensure the ringer has not been switched off.
Is any other phone in the house ringing? Try another handset in that socket...

is it on ringer try turning it off and unpluging it

UNAVAILABLE Indicates the handset is out of range. Or an additional handset is in use. Or there has been a base power failure, in which case you must place all handsets on the main base cradle for 20 seconds to re-register.
