Can not receive calls. Can call out, but incoming calls give a short beep and then a busy signal.

Try disconecting the base unit from power and phone line for 10 minutes and also remove for a minute and reinstall the battery on the hand unit.
Should reset to factory settings.

Best to you

If you have a number of phones installed in your home, disconnect all of them. Then plug in the one at the main incoming junction box to the house. Preferably use an old wired phone. Then test if the incoming calls connect. If they do, the number of phones has exceeded the REN Value set by your Telco. If the phone is still giving a busy signal, contact your Telco and report it as a fault on the line.

This could be a telco problem. Contact Samsung and your carrier to inquire.

phone b.t maybe fault on the line

Hi Janet
Try using a standard phone to call your Fax Line
Connect a phone to this Line to test for voice
Disconnect Fax Machine from Phone Line
Reset Fax machine
The Fax machine is supposed to respond to the right tones being sent down the voice line
If it is not responding & all else works then check your Fax settings for "Receiving"

Sounds like your phone or line is now short circuit and is holding the line so it appears busy to incoming callers. Try disconnecting the pnone and line right up to the incoming point of your house to find the problem.

All incoming calls get a busy signal

You have a short circuit somewhere...start by unplugging the phone from the phone jack in the wall. Wait 15 minutes or so for the line to clear, then try calling your number from another phone. If you hear a ring, the problem is either in your phone internally, or the cord connecting the phone to the jack (which can be replaced at Radio Shack or similar). BTW, are there other phones in the house? If so, do the same with them one at a time to isolate the problem. If disconnecting all phones (and waiting) doesn't clear the problem you have a short elsewhere, such as house wiring, or the phone jacks. But a busy signal ALWAYS indicates a short... good luck.

The HL10 handset lifer is what notifies your headset that you have an incoming call. If you are using the handset lifter and are not receiving the 3 short beeps in your ear piece there are a couple different things that could be going on.
1. The internal microphone could have gone out on the lifter. This microphone is what sends the signal to your headset that you have an incoming call. If the microphone is working you will hear 3 short beeps in your headset.
2. If the volume is too low on your telephone, the handset lifter will not notify the headset of an incoming call, so try turning the volume up on your phone and see if that takes care of the problem.
3. The HL10 handset lifter ships with a ring detector that has a 2.5mm jack on one end and a small round microphone on the other end. This ring detector is intended for phones that do not have the speaker located under the handset. You could try plugging this into the back of the lifter and setting the microphone next to where the lifter is mounted on your phone. This might help pick up the sound of the phones ring tone.

If you are manually lifting your handset out of the cradle and sitting it to the side instead of using a lifter, then you will not receive the 3 short beeps in your earpiece to notify you of an incoming call.

Good luck from Headsets Direct!
