Chapter 16 – Audio Commands

Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 274

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 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.

• This command is not PIN protected.

• This command is supported in airplane mode.
