Using the Flash function
Your cellular system may offer a flash function
service. This system service lets you accept or
make a second call when you already have a call
in progress (e.g. set up a conference call), or send
other information to the network, such as credit
card numbers.

Data and Touch Tones
Pressing SEND sends a displayed number to the
network as a flash, unless it is preceded by a ‘p’
or ‘w’. (In these cases it is sent as a Touch Tone.)
After the phone number has been entered, you
can add extra information which is for ‘flash’
sending to the network.
Contact your service provider for further details.
