Can't get dialling tone and people can not ring us there's a symbol of tow small arrows Don't know How to delete it

check decadic or mtdf frequency setting on printer or from telephone exchange.

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.
Cheers

With the phone in standby mode, press up-arrow or down-arrow. The phone will sound the different ring tones at different volumes. Press the END key when done.

Activating Personal Ring
You can assign special ringer tones to anyone in your phonebook. When your phone gets a call, it looks up the Caller ID information in your phonebook. If you've assigned a personal ringer to that number, the phone uses it so you know who is calling. To turn the personal ringing on or off, follow these steps:

1. Press [Menu/Select]. Select the HANDSET SETUP menu, and then the PERSONAL RING submenu.
2. Move the cursor to select ON or OFF.
3. Press [Menu/Select]. You will hear a confirmation tone.

Selecting a Ring Tone (Handset only)
You may choose from four melodies or three tones for your phone's primary ring tone. Each handset can use a different ring tone or melody. The available ring tones are as listed:

1. Press [Menu/Select]. Select the HANDSET SETUP menu, and then the RINGER TONES submenu.
2. Move the cursor to select a ring tone. As each ring tone is highlighted, you will hear a sample.
3. When you hear the tone you want to use, press [Menu/Select]. You will hear a confirmation tone.

Adjusting the Speaker Volume
Handset Speakerphone: You can choose from six volume levels for the handset speakerphone. To adjust the speaker volume while on a speakerphone call, press the UP Arrow button (to make it louder) or the Down Arrow button (to make it softer).
Base Speaker: You can choose from ten volume levels for the base speaker. To adjust the speaker volume while call screening or playing messages, press [volume +] (to make it louder) or [volume -] (to make it softer).

Adjusting the Audio Tone
If you aren't satisfied with the audio quality of your phone, you can adjust the Audio Tone of the earpiece while on a call. Your phone gives you three audio tone options: low, natural and high; the default setting, Natural Tone, is recommended for hearing aid users. Audio tone adjustments only apply to the earpiece, not the speakerphone.
To adjust the audio tone:

1. While on a call, press [Menu/Select].
2. Move the cursor to select AUDIO TONE, and then press [Menu/Select].
3. Move the cursor to select desired option (HIGH TONE, NATURAL TONE, or LOW TONE), and then press [Menu/Select]. Selected option appears in the display for two seconds, and then the display returns to normal.

Deleting Phonebook Entries
You can delete a single phonebook entry at a time or all phonebook entries at once:
To delete a single phonebook entry:

1. When the phone is in standby, press the phonebook key.
2. Find the entry that you want to delete and press [Menu/Select].
3. Select DELETE. DELETE ENTRY? appears in the display.
4. Move the cursor to select YES.
5. Press [Menu/Select]. You will hear a confirmation tone, and DELETED! appears in the display.

Deleting Caller ID Numbers

1. To delete only one Caller ID number, press the Caller ID button when the phone is in standby, and then find the number you want to delete.
2. Press [Menu/Select] and select DELETE ENTRY.
3. When the phone asks you to confirm, select YES.

1. To delete all the Caller ID numbers, press the Caller ID button when the phone is in standby, and then press [Menu/Select].
2. When the phone asks you to confirm, select YES.

Note: When you delete a Caller ID number, you delete it permanently.

Deleting a Redial Record
If you want to delete a phone number from the handset's redial list, follow the steps below:

1. When the phone is in standby, press [Redial/Pause].
2. Use the UP Arrow button and the Down Arrow button to scroll through the redial list.
3. When you find the redial number you want to delete, press [Menu/Select] and select DELETE ENTRY.
4. When the phone asks you to confirm, select YES. The redial number is deleted.

Resetting the Voice Message Waiting Indicator

1. When you receive a new voice mail message, the new message LED on the top of the handset flashes and VM appears in the handset display.
2. In the event your message alert tone gets out of sync with your phone company's voice messaging system, you can reset back to its original "no messages waiting" state.
3. To reset, press and hold [find hs] on the base for five seconds.
4. A beep sounds and the message alert tone is reset.

@psd4n YOU'RE MY LIFESERVER! <3333

for those of you having this problem, what you need to do (as i so annoyingly discovered) is to 'delete all' in your previously called numbers, then it dials out just fine. lame, but it works. :D

dear,
check this link and hope it will solve the problem

regards,

If you have a BT line and use the 1571 answering facility , when you have a message waiting the dialling tone changes from a constant tone to a split tone. This is to let you know that you have one or more messages waiting.

In order to get the dialling tone to revert to the constant tone you have to deal with the waiting messages in accordance with the options provided i.e Save, Listen Again or Delete. BT say the Split Tone is to let subscribers know when they have a message waiting. This should resolve the Fax problem.

It certainly worked for my phone/fax system.

Good Luck
