During test playback, you can enter the Write command to select another melody and adjust the volume. Also,
you can enter the read command to check the type and volume of the current ring tone, an d to view the status
of playback (on / off). The test ringing signal cannot be activated when a n MTC is ringing (ERROR).
Selecting <volume>=0 during the test, immediately stops playback. After this, ring tones will be muted until you
change <volume> using the write command.
The write command chooses the type and volume of ring tones The settings can be changed no matter whether
or not the ME is ringing. The selected type and volume ar e saved in the non-volatile Flash memory and, thus,
are retained after Power Down. An exception is <type>=0, that can be entered to quickly mute the tone or mel-
ody currently played to indicate an event. <type>=0 only stops immediately t he audible ring tone, but does not
terminate the URC that indicates the event (for example RING). No permanent settings are changed or saved.
Before first using ring tones:
We have chosen to let you decide your own preferences when you start us ing ring tones. Therefore, factory set-
ting is AT^SRTC=3,0,0 (ring tones are muted). To activate ring tones for the very first time, fi rst enter the write
command and simply change the volume. After applying a firmware up date the volume and type selected before
the firmware update will be preserved.
