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.
