2. If prompted, select a block from the list and tap OK .
3. Remove the checkmark next to the current mode by tapping the checkbox next to it.
An asterisk (*) symbol appears next to Block Mode Target and the checkboxes are

the device. If the mode checkboxes are read-only, the block may have been set to
allow only one mode.

5. Tap OK .
6. When the message appears, tap YES to apply and send the change to the device,
