Resetting Avaya 1608-i Phone to factory defaults

After searching around and finding conflicting advice I found the following method for resetting Avaya 1608-i phones running firmware hal1608ual_340D (may work for others as well)

Plug phone in.

When "* to program" shows press *.

When "enter PROCPSWD" shows enter C R A F T # on the keypad.

Press # to all the values shown and when "Enter command" shows (will be the last option) press the mute key and enter the following: C R A F T C L E A R #

"Clear all values?" will show. Press # and # again to confirm.
