■ Show call duration (Menu 4-5)
This function allows you to view the approximate duration of your outgoing and
incoming calls.
You can reset these so-called call timers using the
Clear timers
function (Menu 4-
5-5). For this you need the security code (see
Access codes
on page
107
). Changing
the SIM card does not clear the call timers.
Note: The actual time invoiced for calls by your service provider may vary,
depending upon network features, rounding-off for billing, and so forth.
