This allows you to talk or listen during a call. An additional standard telephone or a fax
machine with a handset is required.
6.1 How to switch between a text and voice conversation
Whilst you are in a call, lift the handset of the telephone or fax machine, which is
plugged into the external socket on the back of your TextLink Textphone.
Then press The display tells you to speak now:
This is the Voice Carry Over mode. If the other person also changes to VCO mode you
can have a conversation.
If your caller switches from text to voice before you do, during a call, this can be
detected by your TextLink Textphone. This will only work if your communications are
set to either V.21 mode or V.18 mode.
The following display will indicate this:
Your textphone will not allow you to type as it is telling you there is no textphone to
send text to. It is asking you to either go to VCO so that you can have a voice
conversation or end the call.
6.2 How to return to text conversation
Press on your TextLink Textphone.
The display shows:
If you get a message telling you the ‘Line is silent’ this means one of three things:
• The caller has not returned to text yet.
• The caller has hung up.
• The caller has a product which uses VCO differently. In this case, which is common
with textphones that have built-in handsets, you must lift the handset again, press
(VCO) to go back to VCO, then press This will force a Baudot text connection.
