C.) Problem: Incoming call cannot be received
Solution: Try to establish a connection in order to check whether the
mobile phone and network are in working order or whether reception
is available. Check the call diversion function, in case this is acti-
vated, and if necessary deactivate it. Check your top-up card in case
this is no longer activated.
D.) Problem: The sender's phone number does not appear when a
call is received.
Solution: The phone number is always switched on automatically for
transmission with this mobile phone. (It can be switched on or off us-
ing the GSM code on page 144.) If the phone number is not transmit-
ted, it may be because the service was previously switched off on the
SIM card (please switch the SIM card phone number transmission
function back on using the GSM code or another mobile) or because
the service was previously switched off by your network operator
(please contact your network operator). The phone number display
can be set using another mobile, your network provider's website or
their Hotline. Using older SIM cards (before 2002) can lead to prob-
lems in transmitting the phone number. SIM card suppliers will nor-
mally exchange new cards for old ones free of charge. If possible,
check by using the SIM card from another network operator.
E.) Problem: The phone cannot be used for the operating time indi-
cated for calls or when switched on and ready for use (i.e. on
standby).
Solution: The battery will only reach full capacity after several charge
cycles.
If the battery is more than approx. 2 years old, it will no longer be ca-
pable of taking a full charge.
We obtained data concerning operating times during optimum net-
work reception conditions, without additional use of the phone by
switching on the keypad illumination or making phone calls. When-
ever phone calls are made, the keys are used more frequently or
where network reception is reduced, the phone consumes more en-
ergy and the battery performance is reduced (sometimes signifi-
cantly). Therefore, for a phone which lies unused at home (within a
reinforced concrete structure to exacerbate reception) and is 3 km
from the transmission mast, the operating time is reduced to 3 days,
as an example.
