Brother Fax T96
The F/T Mode is used to allow the fax machine and the telephones to share the same telephone line. When a call comes in, the fax machine and all extension telephones on that line will ring according to the number of rings you have set for the Ring Delay.
When the Ring Delay is completed, the fax machine will answer the call and determine if it is a fax call or a telephone (voice) call.
The fax machine can determine this by the signal it is receiving on the telephone line. If someone is sending a fax automatically , the sending fax machine will transmit a fax tone (a series of beeps every 3 seconds).
If your fax machine hears these tones, it will receive the fax.

If the fax machine does not hear any fax tones, it assumes it is a telephone (voice) call and will begin ringing the F/T ring tones (double ring) for the length of time you selected for the F/T Ring Time. These tones will only ring on the fax machine's handset (extension or external phones will not ring). At the end of the F/T ring time the fax machine will go into the receive mode in order to receive a manual fax.
(If the call was a voice call and was not answered, the caller will hear the fax receive tones also).

• If you answer the call before the fax machine(during the ring delay period) and determine it is a fax, you can transfer the fax to the fax machine for receiving.
  
  
• If you answer the call on an "extension" phone and hear a beep every 3 seconds (automatic fax) or silence (manual fax), press *51 or *91 for New Zealand (remote activation code) on the telephone keypad, wait to hear the fax machine turn on (chirping sounds) and then hang up.
  
  
• If you answer on the handset of the fax machine and hear a beep every 3 seconds or silence, press the Fax Start or Start/Copy key on the control panel of the fax machine and then hang up the handset.
  
  
• If you answer a call on an "extension" phone during the F/T Ring Time, you will hear the F/T ring tones.
  To release the call from the fax machine, press #51 or #91 for New Zealand (remote deactivation code) on the telephone keypad and you can speak to the calling party.
  
  
• If you pick up the handset of the fax machine during the F/T ring time, you may talk to the calling party immediately.

Call Pickup doesn't ring your phone or light up. Your 5212 phone isn't considered a "display phone" Meaning that the display doesn't have softkeys. These are the 3 keys directly below the display and their function changes as you are using the phone.

Your phone's Pickup Key should be used if you want to pick up a call that is ringing on a nearby telephone... usually only the phones within earshot of your phone.

You must pick up the handset, then either press the call pickup key or dial the call pickup feature code.... this code can be different for every system as it's custom from the install vendor.

I hope this helps.

Solution: Contact local phone company to check the telephone wall jack for low ring voltage.

Ring-in Voltage Facsimile equipment?(fax machines), like other telephone anwering devices, require ring voltage at a telephone jack to answer automatically.? The ring voltage is one of the services provided by the local phone company.

• Low ring-in voltage can cause short bursts of ring tones at the phone jack.
• Callers may hear one or two ring back tones and then ringing will stop and nothing else will be heard.
• Inside the home, the called party will hear a brief ring and then nothing else will be heard. If the telephone handset is lifted, the caller may be on the other end.

To check if the fax will not answer due to low ring-in voltage, do the following:

1. Disconnect the fax at the telephone wall jack.
   
   
2. If an answering machine is available, connect it directly to the telephone jack. If an answering machine is not available, connect a telephone to the telephone jack.
   
   
3. Dial the fax line and see if the answering machine answers the call, listen for uncommon ring tones inside the home or check for similar symptoms as described above. If any of the above symptoms occur, please contact your local telephone company.
