VOICE CONTROL KEYS
Control of voice features of FT15 telephones are fulfilled by making use of four keys:
“Speaker” Key: (Handsfree: It is a feature of telephone that it emits voices into the
room or transmits voices inside the room to the other parties while the handset is still
on hook.) This is the key with red icon that puts the telephone into the “handsfree”
status and that signifies this through an embedded LED. The key is called H/F key, and
the LED inside it is called H/F LED.
Speaker key performs different functions in different cases. These are:
•
When it is pressed while the handset is on hook, the telephone is picked up as
“handsfree” and the H/F LED lights. In this case, a number can be dialed and a
conversation can be made without lifting the handset. Pressing the key during a
conversation terminates the conversation.
•
The H/F LED starts to blink if it is pressed while dial tone or busy tone is being
received over the handset or while a conversation is being made. If the handset is
replaced before the H/F LED goes out, then one continues to receive dial tone or
busy tone, or one can go on with the conversation. The conversation is terminated
if the handset is replaced after the H/F LED has become off.
•
If the handset is lifted during the handset status, then the rest of the conversation
goes on via the handset. Replacing the handset terminates the conversation.
•
While the handset is on hook, in the event that this key is pressed twice
consecutively, the other party can be heard both via the handset and the H/F
speaker. The opposite party would hear the things spoken via the handset only,
but no voice would be transmitted to the opposite party via the H/F microphone.
The conversation terminates by replacing the handset at this status.
•
If “Headset” usage has been activated through menu options, then this key may
also be used for putting the headset on line. Headset usage has been explained in
detail in the “Connection Points” section.
“Volume ” Key: It is used to decrease the level of voice received during conversation
while in the Handsfree mode.
“Volume ” Key: It is used to increase the level of voice received during conversation
while in the Handsfree mode.
Mute Key: The MUTE key with a black icon, which provides interruption of the outgoing
voices during the all conversations and which signifies that via the LED inside it.
Pressing the key for a second time will maintain the voice transmission to the opposite
party again. Please note that this key is used only during the H/F conversations.
