Notes

•Before first using ring tones note that the following settings apply:

We have chosen to let you decide your own preferences when you start using ring tones. Therefore, factory setting is AT^SRTC=3,0,0 (ring tones are muted). To activate ring tones for the very first time, first enter the write command and simply change the volume. After applying a firmware update the volume and type selected before the firmware update will be preserved.

•If no optional parameter is entered, the old value will be kept.

•The test ringing signal (see execute command) cannot be activated while an MTC is ringing (ERROR).

•If an MTC arrives during test playback, test ringing will be deactivated and "normal" ringing reactivated (RING). Likewise, an MOC will also stop test ringing.

•If the <type> is changed while a call is ringing (RING URC) or active, the ME returns OK, but the new melody does not take effect until after the call has ended.

•Users should be aware that when using this AT command quickly after "^SYSSTART" a "+CME ERROR: operation temporary not allowed" is received. The audio data may not yet be accessible, resulting in a short delay (less than 400ms) before the requested AT command response is returned.
