- If you select "Once", the setting changes to "Off" after the alarm sounds.
Call block (Caller ID subscribers only)
This feature allows the unit to reject calls when:
- the unit receives a call from a phone number stored in the call block list as unwanted ("Storing unwanted callers", page 26).
- the unit receives a call without phone number ("Block calls without phone number", page 27).
When a call is received, the unit rings for a short time while the caller is being
identified. If the unit recognizes the call as unwanted, "Caller blocked" is displayed and the unit sends out a busy tone to the caller, and then disconnects the call.
Important:
- When the unit receives a call from a number that is stored in the call block list or a call without a recognized phone number, the call is logged in the caller list (page 29) with ✗ after the call is disconnected.
Storing unwanted callers

Caller ID Service
Using Caller ID service
Important:
- This unit is Caller ID compatible. To use Caller ID features, you must subscribe to a Caller ID service. Contact your service provider/ telephone company for details.
Caller ID features
When an outside call is being received, the caller's name and phone number are displayed.
Caller information for the last 50 callers is logged in the caller list from the most recent call to the oldest.
- If the unit cannot receive caller information, the following is displayed:
- "Out of area": The caller dials from an area which does not provide a Caller ID service.
- "Private caller": The caller requests not to send caller information.
- "Long distance": The caller makes a long distance call.
- If the unit is connected to a PBX system, caller information may not be properly received. Contact your PBX supplier.
Missed calls
If a call is not answered, the unit treats it as a missed call. The display shows
"Missed call". This lets you know if you should view the caller list to see who called while you were away.
Phonebook name display
When caller information is received and it matches a phone number stored in the phonebook, the stored name in the phonebook is displayed and logged in the caller list.
Talking Caller ID
This feature lets you know who is calling without looking at the display.
To use this feature, you must:
– subscribe to a Caller ID service of your service provider/telephone company.
- turn this feature on (page 23).
When caller information is received, the handsets and base unit announce the caller's name or phone number received from your service provider/telephone company following every ring.
The unit announces in English only.
- Name pronunciation may vary. This feature may not pronounce all names correctly.
- Caller ID service has a limit of how many characters can be displayed. If the caller's name is too long, the handset may not be able to display or announce the entire name.
●The announcement is heard at the same level as the ringer volume (page 15, 23).
- If you turn on the answering system and set the number of rings "2" (page 35), the unit does not announce the caller information. If "Toll saver" is selected and there is a new message, the unit does not announce the caller information.
- When you receive a call while on the phone, the 2nd caller's name is not announced even if you subscribe to both Caller ID and Call Waiting with Caller ID services.
Phonebook name announcement
When caller information is received and it matches a phone number stored in the phonebook, the stored name in the phonebook is announced.
Caller ID Service
Ringer ID
This feature can help you identify who is calling by using different ringers for different callers stored in the phonebook (page 18). You can assign a different ringer to each phonebook entry. When a call is received from a caller stored in the phonebook, the assigned ringer rings after the caller information is displayed.
Caller list
Important:
- Only 1 person can access the caller list at a time.
- Make sure the unit's date and time setting is correct (page 13).
Viewing the caller list and calling back
1 [MENU] → [#][2][1][3]
2 Press [▼] to search from the most recent call, or [▲] to search from the oldest call.
3 To call back, press [→]. To exit, press [OFF].
Note:
- If the entry has already been viewed or answered, "√" is displayed, even if it was viewed or answered using another handset.
Editing a caller's phone number before calling back
You can edit a phone number in the caller list by removing its area code and/or the long distance code "1".
1 [MENU] → [#][2][1][3]
2 [▼]/[▲]: Select the desired entry.
3 Press [EDIT] repeatedly until the phone number is shown in the desired format.

Caller ID number auto edit feature
Once you call back an edited number, the unit remembers the Area Code and Format of the Edited Number. Next time when someone calls from the same Area Code, caller information is customized by the unit as follows:
- When the call is being received, the Caller ID number is displayed in the same Format as the Edited Number. - After the call is ended, the phone number of the caller, when reviewed from the Caller list, is displayed in the same Format as the Edited Number.
For example, you can use this feature to set the unit to ignore the area code of callers in your area, so that you can call these local numbers using caller information without dialing the area code.
To activate this feature, you must edit an entry in the caller list, then call that number. After that, phone numbers from that caller's area code are edited automatically.







Caller ID Service
This feature can be turned on or off (page 22).
Note:
- Phone numbers from the 4 most recently edited area codes are automatically edited.
- If you move to another area, you can turn this feature off to erase previously edited area codes. To use this feature again, turn it on and reprogram the area codes you want to edit once again.

A plug and jack used to connect this equipment to the premises wiring and telephone network must comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA. A compliant telephone cord and modular plug is provided with the product. It is designed to be connected to a compatible modular jack that is also compliant.
The REN is used to determine the number of devices that may be connected to a telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the total RENs, contact the local telephone company. For products approved after July 23, 2001, the REN for the product is part of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point (e.g., 03 is a REN of 0.3).
If this equipment causes harm to the telephone network, the telephone company will notify you in advance that temporary discontinuance of service may be required. But if advance notice isn't practical, the telephone company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations or procedures that could affect the operation of the equipment. If this happens the telephone company will provide advance notice in order for you to make necessary modifications to maintain uninterrupted service.
If trouble is experienced with this equipment, for repair or warranty information, please contact a Factory Service Center or other Authorized Servicer. If the equipment is causing harm to the telephone network, the telephone company may request that you disconnect the equipment until the problem is resolved.
Connection to party line service is subject to state tariffs. Contact the state public utility commission, public service commission or corporation commission for information.
If your home has specially wired alarm equipment connected to the telephone line, ensure the installation of this equipment does not disable your alarm equipment. If you have questions about what will disable alarm equipment, consult your telephone company or a qualified installer.
This equipment is hearing aid compatible as defined by the FCC in 47 CFR Section 68.316.
When you hold the phone to your ear, noise might be heard in your Hearing Aid. Some Hearing Aids are not adequately shielded from external RF (radio frequency) energy. If noise occurs, use an optional headset accessory or the speakerphone option (if applicable) when using this phone. Consult with your audiologist or Hearing Aid manufacturer about the availability of Hearing Aids which provide adequate shielding to RF energy commonly emitted by digital devices.








Useful Information

1) Remain on the line and briefly explain to the dispatcher the reason for the call.
2) Perform such activities in the off-peak hours, such as early morning or late evenings.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Privacy of communications may not be ensured when using this phone.
CAUTION:
Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this device.
NOTE:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Some cordless telephones operate at frequencies that may cause interference to nearby TVs and VCRs. To minimize or prevent such interference, the base of the cordless telephone should not be placed near or on top of a TV or VCR. If interference is experienced, move the cordless telephone further away from the TV or VCR. This will often reduce, or eliminate, interference.
