The FJ80 and FJ80ii have a locking feature which will prevent changes to all settings via the touchscreen. You will still be able to use your unlocked FJ-X2m or host FJ speed light to manipulate the power, compensation and other functions of a locked off camera Client unit screen. To engage the lock mechanism, simply long press the home button until the lock icon shows on the screen. To disengage lock repeat the long press of the home button.
