So every time you answered a question a red light would start to flash? Registering with your MACID or student # wouldn't be the problem. You can still record your participation even if you haven't yet tied your iclicker with your macid.
To change frequency you'll need the two letter code from your prof and follow the instructions:
If you have chosen a non-standard frequency (e.g. BA) in Settings and Preferences, i>clicker will alert your students to this change when you begin polling. Students will be instructed to:
- Press the On/Off (power) button on their clicker until the blue Power light begins flashing (about 2 seconds).
- Press the new two-letter code (that you’ve designated in your Settings/Preferences). A green Vote Status light will indicate your students have successfully reset their remote frequency.
Default frequency is AA so unless your told specifically by the prof to change don't do this.
