Md 760 series cordless telephone system

All phone are displaying a "no line" message. When you try to call in to my number, you get a busy signal. Cannot make outgoing calls. I've had the base unit with 3 more phones for 2-3 years and have never had any problems. I have unplugged all extra units, just keeping the base unit on. I've tried it on other phone jacks in the house, still the same message

Re: md 760 series cordless telephone system


Try unplugging all telephone (including the base unit), then try to call the number again. If there is still a busy signal, then the problem is with your telephone line/connection and you need to call your phone provider. On the other hand if the number rings, then chances are that base unit is defective (or one of your other phones physically connected to the tel line.).

To verify that it is the base unit or one of the other wired telephones,  reconnect them one by one and determine which of them will cause the busy signal. Problems like this can be caused by a power surge, near lightning strike or a simple component failure.

If it is the base unit, it is very likely an electronic problem and therefore would require familiarity with components and circuitry diagnosis, soldering and use of a DVM. Perhaps your best bet would be to seek the services of a qualified phone technician.

Hope this be of some help/idea. Post back how things turned up or should you need additional information.

Good luck and kind regards.

I have a cordless phone that every time I try to make a phone call the busy signal comes over my phone how can I correct this problem

Are you getting a continuous busy signal, or just five or six quick beeps then a dial tone?

If the latter, you have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

If the former, please add a comment to this question and specify the make and model of your phone.

Phone not working

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.

My Vtech detct 6.0 is displaying a No line message. I tried moving it to a jack that I know is working but it still has the same message. There is no dial tone and no incoming calls.

The battery detect circuit of the cordless phone has failed. "Battery" is the 24VDC signal
sent by the CO (Central Office) to each telephone that goes off-hook.
Fix: get the phone serviced (hopefully under warranty), or replace.

Trying to check the voicemail on phone. how do i do that?

If you mean the voicemail messages taken by your phone service provider when your line is busy, there are two ways normally used.

The first is to call your own number. When your message starts, press the "*" button. (Usually it's the star, but it might be different on your system. You might need to call your provider's customer service for details.) Then you're prompted for your passcode. Once in the voicemail system, voice prompts tell you which buttons to press to play messages, delete them and so on.

The second way requires you to dial a different phone number to get messages. You'll need to contact your service provider or check their website to find the access number for your telephone number if necessary.

How do i put the ring tone back in the handset

    Does the Phone Power Up?
  1. When you pick up your GE cordless phone and press a button, the phone should beep as a confirmation that a button has been pressed. If the telephone handset does not beep, or if it does not respond to any buttons, the battery may be in need of a recharge. Verify that the cordless phone base unit is plugged in to an electrical source, then place the handset into the charging cradle. If no lights illuminate on the phone, or if charging fails to correct the issue, clean the metal charging contacts on the cordless handset and place the phone back on the charger. If it still fails to respond or to charge, the unit may need to be serviced or replaced.
  2. Does the Battery Hold a Charge?
  3. If the cordless phone charges up and appears to be ready for use but dies after only short periods of use, the internal rechargeable batteries may need to be replaced. Replacement batteries are widely available at electronics and discount retail stores. Note your phone's exact model number, as this number will be necessary when purchasing a replacement battery.
  4. Listen for a Dial Tone
  5. If the GE cordless phone powers on, and beeps when you press keys, but no dial tone is heard, one of three problems is the likely culprit. The phone's batteries may have an insufficient charge to fully power the phone, a condition that can be corrected by simply placing the phone back in the charger. If the batteries are charged, but no dial tone is heard, it is also possible that another telephone in your home or office is "off hook" or in use; verify that all telephones, fax machines and modems are securely on the hook. If there is still no dial tone, your telephone service may have been disconnected or require service by your local telephone company.
  6. Listen for Static
  7. On some GE cordless phone models, particularly older models, static may be heard if the radio signal between the handset and base unit experiences interference. Common sources of interference include unshielded electronics, appliances, and radio transmitters, as well as high-tension power lines. If your phone offers an option to change channels, try several different channels to see if the static is eliminated. If static continues to exist, or if static can be heard on wired phones sharing the same line, your telephone line may require service.
  8. Verify Your Handset is Registered
  9. Some models of GE cordless phones may display a message on the display screen that the handset needs to be registered. If this message appears, move the handset close to the base unit and press the "Prog/Mute" button near the bottom of the handset. Next, press the "Pager" button on the base unit (your handset may instruct you to perform this step). Finally, press the "Prog/Mute" button on the handset one more time to complete the registration process. Your GE cordless phone should now work correctly.The GE Cordless Phone brand is designed to deliver the conveniences of cordless home service with quality sound and features. There are many models of the GE Cordless Phone. The most current models, including the DECT 6.0, have standard features such as call waiting, caller ID, visual ring indicator, phone number memory and digital answering systems .
  10. Before you use your GE Cordless Phone, ensure that you have all the parts. Your cordless phone package should include the phone base, a handset battery pack, a battery compartment cover, the cordless handset, a wall mount bracket, and a telephone line cord and AC power adaptor. Once you have confirmed that you have all of your parts, insert the handset battery pack into the handset and replace the battery compartment cover. Insert your telephone line cord and the AC power adapter into the phone base. The phone base identifies the telephone line as TEL LINE and the adapter as AC. Plug the phone base into the electrical socket. Place the cordless handset into the base. Allow the phone to charge for at least 16 hours before its first use. Failure to fully charge the battery before its first use will result in poor battery performance.
  11. Once you have fully charged your phone, you can proceed with setting up your phone's features. If your cordless phone includes an answering system, complete this setup process first. Turn on the answering system by pressing the on/off button. The message indicator light will display. The cordless phones are defaulted to English as the selected language. To change your language preference, press the "Skip" button for two seconds. The language will change to Spanish. Next, you will set up your voice time and day stamp. While the answering system is on, press the "Answer" button on your handset for two seconds. The phone will enter the answerer mode. Press the "8" key. This will take you to the time/day setup menu. Use the number keys to set the hour and minutes. Use the volume up and down arrows to set the AM/PM. Press "#" to save. The cordless handset will also require that you give it a name. Press the "Mute" button for two seconds until the handset reads "ENTER NAME." Enter the name of the handset by using the touchtone keypad. Press the "Mute" button to save. Enter the default area code by pressing "Mute" until the phone displays "AREA CODE." Enter your three-digit area code and press the "Mute" button to save.
  12. GE Cordless Phones are designed to be simple and convenient to use. To place or answer a call, press the TALK button. You can pre-dial a number by dialing the number before pressing the TALK button. When you are ready to make the call, press TALK and the phone will dial automatically. To answer a call that is waiting on the other line, press the FLASH button. If you experience call interference or bad reception while on a call, press the CHANNEL button until your line clears
