No dial tone and "line in use " message

the wire that is used to connect the line to the telephone is not proper...

It\'s in system programming: feature CONFIG, Terminals & Sets, enter ext #, Prime Line: set to I/C (for intercom dial tone) or Line xxx. It is probably set to None based on your description.

Hi Pam,
Try these..1...remove your telephone line from base unit and fix it into a working land phone and check whether is it having normal dial tone.If it's having engage tone(beep beep...)remove paralleled phones and re connect to cordless base unit.
2.If line is ok (normal dial tone with full volume) & still display indicates line is busy, your main base unit must be having faulty components inside.Commonly these defects happen in thundering or surges through telephone lines.You have to take full set to a repair shop.

Resetting the voice message waiting indicator
When you receive a new voice mail message, the new message LED on the top of the handset flashes. In the event your message waiting light gets out of sync with your phone company's
voice messaging system, you can manually reset it back to the "No messages waiting" state.
1. Press and hold FiND on the base for five seconds.
Note: The handsets connected to the base will start to beep, however, keep pressing for five seconds.
2. A beep sounds and the message alert tone is reset.
Changing the dial mode
Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most base networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you will need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, please follow the steps below to modify your phone's settings:
1. Press MENU/SELECT.
2. Select the Global Setup menu, and then the Dial Mode submenu.
3. Scroll to highlight Pulse.
4. Press MENU/SELECT. You will hear a confirmation tone.
If you ever need to change the dial mode back to tone dialing, follow the same procedure, but select Tone in step 3.

Finally for future ease of use, here is a link to the user manual were I copied the above information from:

The battery in the handset could be bad . First I would test that the base unit is recieving dial tone by pressing speaker button on base unit. If there is dial tone then problem is in handset or in base unit communication to handset. Try resetting power to base unit. Check manual for any re-initialization procedure. If the base unit is not receiving dial tone then I would test that the phone line is delivering dial tone to the base unit by connecting a known good phone to the line cord. If the dial tone is not present , problem could be in line cord from outlet, outlet, building wiring, or service provider.

The one with out the dial tone put on the base with the phone line for 5 mins to register the hand set.

Here's what the manual says: Changing the Dial Mode (Tone or Pulse Dialing) (HS1 only) Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most phone networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, follow the steps below to modify your phone?s settings: With the phone in standby, press and hold [cid/menu]. Press [vol/ / ] to move the pointer to select DIAL. Press [select/channel] to set the phone to pulse dialing. Press [end]. Return the handset to the base. The handset communicates the new setting to the base, and the base activates the setting on any other handsets. Hope this helps out. K
