Intensity of Field (IOF)
The Intensity of Field (IOF) feature indicates the strength of the received radio
signal. The IOF is indicated by the light indicators. The feature can be activated
with a DTMF telephone connected to the terminal’s trunk connector. To activate
the feature, key in
777**#
. The feature is automatically deactivated when the
DTMF telephone’s receiver is replaced on the hook. For further information on
the IOF feature, see “3. Setting up the terminal” on page 18.
Faster call setup
Faster call setup allows a faster call establishment. The last 10 different dialled
numbers are stored in the memory of the Nokia 22. If the dialled number match-
es one of the stored numbers, there is no delay before the terminal sends the
number and the call is established immediately.
Note:
Only successful (answered) calls are stored in the terminal’s
memory.
AutoPIN security feature
The Nokia 22 has an AutoPIN security feature. It saves the PIN code in the
terminal’s memory when the code is entered for the first time or when the code
is changed. In addition, the AutoPIN feature enables device recovery after
occasional power cuts without on-site intervention. The terminal enters the PIN
code automatically the next time it switches on and requests the PIN code. For
changing the PIN code, see “ Security options” on page 53.
Use of the SIM card in other GSM terminals or mobile phones can be prevented.
The user does not have to know the PIN code. However, other SIM cards can be
used with the terminal. The AutoPIN feature can be deactivated using the Nokia
22 Configurator Software.
The default value is that the AutoPIN feature is active.
