The message KEYGUARD OFF is briefly displayed
indicating that the keyguard has now been deactivated.
When keyguard is activated:
• To answer a call, press the SEND key. During the
call, the keypad remains unlocked and the phone
can be operated in the normal way.
• To end a call, press the END key. After the call is
ended, the keyguard automatically becomes active
again.
• The phone can not be switched off before the key-
guard is deactivated.
Note: When the keyguard is activated, calls may be
possible to the emergency number programmed into
your phone e.g., 911 or another official emergency
number). However, one-touch emergency dialing
(‘the 9 key’) does not operate.
Send DTMF (Menu 17)
You can transmit numerical information as a series
of tones, using the DTMF facility (e.g. to check for
messages in your answering machine). There are two
ways to send DTMF tones:
Manual Dialing:
³
Make the call in the usual way.
·
When the call has been answered, enter the
numbers. Each number is sent immediately, as a
DTMF tone. The length of the tone depends on
how long you press the key.
Automatic Dialing:
³
Make the call in the usual way.
·
When the call has been answered, use the RCL key
to recall a stored ‘DTMF’ number from a memory
location (e.g. for location 23, press
RCL 2 3 ).
»
To send the whole number (displayed) as DTMF
tones, press
MENU SEND , or MENU 1 7 . A series
of tones, each tone representing a digit of the
DTMF number, will be heard.
The special characters ‘+’, ‘p’ and ‘w’ are used for
DTMF dialing; these are available on the
* key.
