Note:
Your unlock code prevents unauthorized persons from
using your telephone. Be sure to memorize this code
carefully. The code is a three digit number.
If you enter an incorrect code, the system returns to the
menu for entering the unlock code.
The unlock code must be entered when the telephone is
switched on for the first time (if phone is in lock mode),
but not if you switch to it from another system (i.e.
radio).
The emergency number programmed in memory loca-
tion 1 can be used even if the unlock code has not been
entered.
“NO SERVICE” - this message will appear in case the
phone is not registered in a network or the network is
no longer receivable because of bad receiving condi-
tions. In this case, the emergency call number cannot be
used.
If the telephone is ready for operation “READY” will
appear. In the display the received signal is indicated by
1 to 5 bars, with 5 indicating a strong signal. If you are
not in a home network, the roaming indicator “R” will
be shown.
