Use the built-in answering system to record your messages
Your Voicemail service can bundle in your telephone plan. As such, you would need to contact your telephone service provider to disable it.
*TIP: Can I switch back to Voicemail service if I want to?
As long as your telephone plan includes the Voicemail service, you can still re-enable it through your service provider.Use the voicemail service to record your messages
Simply turn off the Built-in answering system at any time, and you can use the Voicemail service only.Use both the Built-in answering system and the Voicemail service to record messages
By default, the Voicemail service is usually set to answer after 2 rings, while your Built-in answering system is set after 3 rings. Please check with your telephone service provider to learn how to set your voicemail settings.Suggest to set your Built-in answering system to answer calls at least 2 rings earlier than your Voicemail service. In other words, if your answering system sets to answer after 3 rings (by default), then you need to set the Voicemail service to answer after 5 rings.
What happened is that if you on a call or the answering system is already recording, and you receive ANOTHER incoming call, then the third caller is able to leave a Voicemail message.
On the other hand, if you are not on a call nor the answering system is recording, the incoming caller can leave a message directly to the Built-in Answering system.

Tip 1 of 8
If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause static/noise, squealing (similar to fax tones), caller ID disruption and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.
In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.
Please contact your service provider to obtain DSL filters and installation information. -

Tip 6 of 8
If your phone shares a power outlet with a modem, or if it is plugged in to a shared surge protector, try plugging the phone (or modem/surge protector) in at a different location. If this solves the problem, re-locate your phone or modem farther apart from one another, or use separate surge protectors. -

Why am I not receiving caller ID on my phone?
-
Caller ID and Call Waiting ID are subscription services, available from most local telephone service providers. You must subscribe to these services in order for the features to work on your phone. Contact your local telephone service provider for more information.
In addition, your caller must be calling from an area that supports caller ID.
Both you and your caller’s telephone service provider must use compatible caller ID systems.
If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause caller ID disruption, static, noise and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.
In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.
Please contact your service provider to obtain DSL filters and installation information.
Caller ID and Call Waiting ID may not be available for every call. Common reasons are incompatibilities between your and your caller’s service, transmission errors and answering calls before the ID data is received.
How can I improve the sound quality on my cordless phone?
-
If your handset has a CHANNEL (or CHAN) button, press it in order to improve the sound quality. You may need to press the CHANNEL button more than once.
The handset may be out of range. Try moving closer to the base. The handset(s) and base can only communicate over a certain distance which can vary with their placement, the weather and the operating environment of your home/office.
If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause static/noise, squealing (similar to fax tones), caller ID disruption and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.
In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.
Please contact your service provider to obtain DSL filters and installation information.
A low battery pack may affect the sound quality. You may need to charge the handset. Also, try repositioning the handset against your ear until the sound quality improves.
Electronic products (i.e., 802.11 wireless networks, radios, radio and pager towers, cell phones, intercoms, room monitors, televisions, personal computers, kitchen appliances and other cordless phones) can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices.
Appliances or other cordless phones plugged into the same circuit as the telephone base can cause interference. Try moving the appliances or telephone base to another outlet.
Microwave ovens may operate on the same frequency as your telephone. You may experience static on your telephone while the microwave oven is operating. Do not install your cordless telephone in the same outlet or near the microwave oven.
Disconnect the telephone base from the modular jack and plug in a corded telephone. If calls are still not clear, the problem is probably in the wiring or local service. Contact your local service company (charges may apply).
If your phone shares a power outlet with a modem, or if it is plugged into a shared surged protector, try plugging in the phone (or modem/surge protector) at a different location. If this solves the problem, relocate your phone and modem farther apart from each other, or use separate surge protectors.
The layout of your home or office may be limiting the operating range. Try moving the base to another location, preferably a higher location for better reception. If your telephone base has an adjustable antenna, ensure it is pointing up.
My telephone handset appears to be dead. What should I do?
-
Tip 1 of 3
If your handset responds in any way (beeps, displays a message on the screen, etc.) then it is not dead. Please review the Frequently Asked Questions list to check for a more specific symptom to your problem.
A common cause for dead handset symptoms is a dead battery. We recommend that you initially charge the handset battery for 16 hours. On average, this provides 5 hours of talk time and 6 days of standby. If the handset does not hold a charge or seems dead, we suggest the following:
• Please verify that the handset battery is securely plugged into the back of the handset.
• Check that there is power to the base and cradle. If there is power and the handset is placed face up, the CHARGE light on the base will be on.
• Place the handset in the cradle and charge it overnight, making sure that the dialpad is facing up.
-
Tip 2 of 3
If the handset is not responding normally, you may need to reset your telephone system. Complete the following steps to reset the telephone system:
Step 1: Disconnect the power to the telephone base.
Step 2: Disconnect the handset battery.
Step 3: Wait a few minutes and then reconnect the power to the telephone base.
Step 4: Reconnect the handset battery
Step 5: Wait about one minute for the handset to re-establish a link with the telephone base and then test the phone again.
NOTE: After resetting the telephone system, you will need to reset the clock. If the time is not set, CL will be shown on the answering system’s display.
NOTE: If you have caller ID service, the time will automatically be updated whenever caller ID information is delivered. However, since caller ID delivers the date, rather than the day, you must program the year once so the system can derive the day of the week.
To set the day and time, confirm that the answering system is turned on and then complete the following steps:
Step 1: Press TIME/SET. The system will announce the current setting.
Step 2: Press TIME/SET again. The system will announce the current day setting.
Step 3: Press CHANGE on the base until you hear the correct day.
Step 4: Press TIME/SET. The system will announce the current hour setting.
Step 5: Press CHANGE on the base until you hear the correct hour.
Step 6: Press TIME/SET. The system will announce the current minute setting.
Step 7: Press CHANGE on the base until you hear the correct minute.
NOTE: Pressing and holding the CHANGE button when setting the day and time will increase the minutes or years by 10.
Step 8: Press TIME/SET. The system will announce the current year setting.
Step 9: Press CHANGE on the base until you hear the correct year.
Step 10: Press TIME/SET to confirm. The system will announce the new day and time setting followed by a confirmation beep. -
Tip 3 of 3
You may need to replace the rechargeable battery, especially if it has been in service for more than one year. To find a replacement, refer to our VTech Battery Finder. If a battery for your model is unavailable, you can search the internet using the key words cordless phone batteries for an on-line supplier. If you prefer to purchase locally, you can look for a replacement battery at your area consumer electronics retailers. It is recommended that you take your present battery with you to insure your replacement is the correct size and has the correct plug (where applicable) and specifications.
