Home Answering Machines
If you choose to use your home answering machine instead of the voicemail provided by your MF279T,
you will need to set your answering machine to pick up calls before network voicemail, which is fewer
than four (4) rings. If you have a standalone answering machine, you can connect it to the "Phone 2" port
on the back of your MF279T.
Adjusting Volume
Use your home phone's volume adjustment if available. Alternatively, the volume of the MF279T can be
adjusted. Four volume levels are available (level 1 to level 4) with the default setting at level 4. While on a
call, press ** to decrease volume or press ## to increase volume. Each time ** or ## is pressed, the
volume level is decreased or increased one volume level. To exit Volume Setting Mode, press any other
key or wait five (5) seconds.
Powering On/Off
The
ON/OFF
button is used to turn your MF279T on or off. When powered off, the MF279T will no longer
send or receive calls, but it will continue to charge the back-up battery if still connected to the wall outlet.
To turn on your MF279T, slide the
ON/OFF
button to the
ON
position until the power light stays solid
green, if connected to a power supply (it will blink green if on back-up battery). To turn off your MF279T,
slide the
ON/OFF
button to the
OFF
position until all the lights turn off.
TTY Support
TTY (Text Telephony) and TDD (Telecommunications Device for the Deaf) are supported by the MF279T.
In order to use the TTY network, you must have a TTY-compatible phone and be in TTY mode. Note that
most digital wireless devices are TTY-compatible.
Dial *983*889*n# to set the TTY mode.
n = 0: TTY off mode. The standard voice speaking mode and listening mode. This is the default
setting.
n = 1: TTY full mode. Transmit and receive the TTY characters.
n = 2: VCO mode. Receive TTY characters but transmit by speaking into the speaker.
n = 3: HCO mode. Transmit TTY characters but receive by listening to the receiver.
