No dialling tone - just a beeping sound

Tried new batteries?

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.

The ring from the telephone is picked up by the internal microphone on the HL10 Handset Lifter, typically for most phones, the lifter sits directly over the speaker grill on the telephone where the sound comes out. For telephones that curve out on the left side and don't have a straight edge, there is an accessory called a "Ring Detector" which is used. Here's a link:

If the internal mic on the lifter has gone out, you can plug the ring detector into the handset lifter and just stick the ring detector over the speaker grill to pick up the ring. Plugging this into the lifter will bypass the internal mic, this accessory would have come with your HL10 lifter. You can also check the ring volume on the telephone, and you can also try adjusting the ring tone on the phone (sometimes it will pick up one ring tone better than another). Here is a link below if you need to order a new ring detector:

Here some solutions for your problem + a link to the user manual.

**Selecting the Ring Tone and Volume
Your phone has five different ringer tone/volume combinations you can choose from.
To select the ringer:
1) With the phone in standby, press [vol/ / ] or [vol/ / ].
2) The phone will sound the different ring tones at different volumes. To turn the ringer
off, select RINGER OFF.
3) When the phone sounds the ring tone and volume you wish to use, press [end].


**Temporarily Mute Ringer
If the handset is off the base while an incoming call is ringing, simply press [end] to mute
the incoming ring. The ringer will sound with the next incoming call.
Note: You can only mute the handset ringer if the handset is off the base when the phone starts
ringing.

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!

Just a suggestion (without knowing what troubleshooting steps from your manual you may have taken): Remove the batteries from the back of the handset and then put them back in after a few moments. My Panasonic KX-TGA8231B (DECT6.0) phones were acting up just like your Uniden is. All functions returned after this power interrupt "reset" with the batteries was done. Hope that helps. Good luck. - - -Gerry

Actually what she was hearing was the ring tone in her headset when a incoming call comes in. The sensitivity on the handset lifter that picks up the ringing on a incoming call was set all the way up and was picking up interferance from the headset base as they have the tendency to buzz when placed right next to the phone. I just turned down the ringer sensitivity with the adjustment on the handset lifter and that took care of the problem. Thanks for your time.
