You have an ongoing push-to-talk connection.
Your push-to-talk connection is in the do not
disturb mode, because the ringing type setting
of your device is set to Beep once or Silent, or
you have an incoming or ongoing phone call.
In this mode, you cannot make PTT calls.
Volume control
To adjust the earpiece volume during a phone call or
the volume of the media applications, use the volume
keys.
Memory
There are two types of memory into which you can save
data or install applications: device memory and
memory card.
Free memory
To see how much memory is currently in use, how
much free memory remains, and how much memory is
consumed by each data type, select Menu >
Options > Memory details > Phone memory or
Memory card.
Tip: To ensure that you have adequate memory,
transfer data regularly to a memory card or
computer, or use File manager to delete files you
no longer need.
After you install applications to a compatible memory
card, installation files (.sis, .sisx) remain in the device
memory. The files may use large amounts of memory
and prevent you from storing other files. To maintain
sufficient memory, use Nokia PC Suite to back up
installation files to a compatible PC, then use the file
manager to remove the installation files from the
device memory. If the .sis file is a message attachment,
delete the message from the Messaging inbox.
Memory card
Select Menu > Tools > Memory.
If you cannot use a memory card in your device, you
may have the wrong type of memory card, the card may
not be formatted for your device, or the card has a
corrupted file system. Your Nokia device supports the
FAT16 and FAT32 file system for memory cards.
MicroSDHC
This device uses microSD and microSDHC
memory cards.
To ensure interoperability, use only
compatible memory cards with this device.
Check the compatibility of a memory card with
its manufacturer or provider. Other memory
cards than microSD and microSDHC cards are not
compatible with this device. Using an incompatible
memory card may damage the memory card as well as
the device, and data stored on the incompatible card
may be corrupted.
