4.2 AT*E2APR M2M Audio Profile Manipulation
This command allows the maniuplation and storage of the audio
“profiles” stored in the MS. The requirement for the 2nd and 3rd
parameters depend on the operation being carried out.
Using the command you can:
• Set one of the three audio profiles 0, 1 or 2 as the current profile.
This will load the profile's settings from NVM and implement them.
• Read one of the audio profiles. The current settings for the profile
number defined will be displayed.
• Copy all parameters from one profile into another.
• Reset any of the profiles. This will reinstate the factory defaults for
the profile:
- 0 is the handset profile,
- 1 is the portable handsfree profile,
- 2 is the car kit profile.
• Set a profile as the default profile on next power up.
