STANDBY AND TALK TIMES
Your DB500 works closely with the network you are using to provide the services you need, and the standby and talk times achieved will depend
on how you use the phone and choices made by the network operator.
In particular, your location within the network, the frequency at which this location is updated, the type of SIM you have, your reception of area or
'cell broadcast' messages and the use of Full Rate or Enhanced Full Rate speech, as well as other factors, will affect both standby and talk times.
If you need to maximise the standby time of your DB500, you may choose to switch on 'Area Messages Power Save Option' (see page 51).
