How do I Erase a Recorded Message in ECO2?
You can erase messages that have been recorded in Activities and Pages and you can erase messages that have been recorded and stored under icon sequences.
To erase a recorded message you simply record over the old message or Clear Key Contents.
To Erase a Recorded Message in an Activity
To erase a message on a PAGE, just select the Page you want in step one.
We will erase the recording you just made in the ME Activity.
1. If the NAME key is still visible in your Activity Row, select the SET-UP key 
on the front of your case, then select the NAME key. If it is not visible, select the ME Activity, then select the SET-UP key then select the NAME key.
2. Make sure the Type of Message option is set to Recorded Speech. Select the Record Message key.
3. Record a new name. This will erase the old name and replace it with the new name.
4. Listen to your recording and select OK when you are satisfied.
To Erase a Recorded Message stored under an Icon Sequence
1. Activate the TOOLS key to go to the Toolbox.
2. Select ERASE CORE.
3. Select the icon sequence of the message you want to erase.
4. Select OK. You see the warning box below:
5. If you still want to erase the message, activate YES. If you change your mind, activate NO.
6. The Text Display Area tells you that the sequence has been erased.
You can also erase a message by recording over it. Select STORE CORE in the Toolbox.
Instead of choosing a new icon sequence, select the sequence you want to record over.
Note: You cannot “edit” a recording; you have to either erase it or record over it
