2. Change the direction of the handle
3. After adjusting the handle, tighten the screw to the handle.
4. Repeat the same steps for the other panel.
Compatibility test:
One test to see if the new lock is compatible with your existing
multipoint locks is to check if it can fully retract the hooks and bolts on
your multipoint mechanism.
Step 1:
Mark the current position of all bolts/hooks on your existing multipoint lock. 
Step 2:
From the inside:
1. Locate the internal lock body on the spindle.
2. Align the lock with the door and hold it firmly.
3. Lift the handle fully to throw 
Step 3:
Take the front body(fingerprint handle) and turn the spindle receptor so that the
arrow POINTS AWAY from the handle. — "It's the opposite of what is suggested
on the lock! We do this only for the test
part!" 
Step 4: 
From the outside:
1. Locate the front body on the spindle.
2. Align the lock with the door and hold it firmly.
3. Push the handle fully downward to retract the bolts.
Step 5:
Now, check if all bolts and hooks have fully retracted to the marked position. We passed this test if bolts don't prevent you from closing the door!
Tip: You can now return the spindle receptor so that it POINTS TOWARDS the handle. 
Installation:
Step 1: Installing the sliding screw casing and the spindle 
1. Select suitable sliding screw studs for installation
according to the thickness of the door
2. Install the square shaft. The arrow is in the
same direction as the handle
3. Install the weatherproof rubber plates
Step 2: Installing the front panel 
Thread the power cord, studs and square shaft through the door hole and secure to the door.
Step 3: Installing the back panel
1. Open the back panel cover by tightening the bottom screw clockwise with a screwdriver 
2. Loosen the screw, remove the fingerprint component
3. Install the waterproof rubber plate to the back panel
4. Select screws that t the thickness of the door to secure the front and back panels
5. Connect the front power cable to the back panel
6. Install the fingerprint component
Step 4: Inserting the batteries 
1. Insert the batteries.
2. Turn the screw at the bottom of the lock counterclockwise to secure the panel
Tips:
Lift the handle to engage the deadbolts/hooks and then pull the handle down to disengage. The internal handle should always open the door.
TEST: Try pulling the outer handle down. It should move but do nothing. Then insert the keys and turn. Try lifting the handle and then pull it down. This time the latch/hooks should retract.
Note: Simpled Smart Lock comes with an auto-lock feature. It means the spindle doesn't engage from the outside
when pushing the handle downward unless you gain access with a fingerprint, passcode, etc.
In multi-point locks, the bolts/deadbolts/hooks will engage when you lift the handles. Otherwise, the door may
only be held on one latch. So it's always recommended to lift the handles to engage the multi-points.
Don't use chemicals for cleaning as it may affect the guarantee. A soft,
damp cloth is best for gently cleaning without scratching the surface.
