I found this online. You will lose and data you have stored.
I am not sure what user "data to make the unit usable" means.

It could be waypoints, maps ?
Be careful.
76/Map 76/Map 76S
The reported method to completely reset on of these units hold the "menu" key and the "quit" key down and then press the "power on" key. Hold for a full 7 seconds and then release. As with the other units all information will be lost and you will need to reload the almanac and all your saved user data to make the unit usable.
For the 76S try this sequence to master reset it. Press and hold quit, Menu, and the rocker down key. Then press and release the power on key. release the rocker down and wait for the welcome display. Now release the quit and menu keys.
