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).
IMPORTANT BATTERY CHARGING INFORMATION
Charging a very low battery
The battery’s charge continues to drop after the
Recharge Battery
warning is displayed. In extreme cases where the battery is left uncharged
for some considerable time after this warning is displayed a trickle charge is used to slowly top-up the battery to the safe level at which ‘fast
charging’ can begin. The phone exhibits no visible signs that it is being charged whilst in trickle charge mode (i.e. the charging icon is not
displayed) but normal operation is resumed once fast charging begins. The phone can be in trickle charge for a few hours before fast charging
starts if the battery is left uncharged for some days after the Recharge Battery warning is displayed.
