5.1 Pre-Installation Checks
- Verify TV Compatibility: Check your TV's size, weight, and VESA pattern against the specifications in Section 4.
- Identify Wall Type: Determine if your wall is wood stud, concrete, or brick. Do not install on drywall without studs.
- Check Cable Outlets: Ensure the mounting location does not obstruct cable ports on your TV.

5.2 Installation Steps
The installation process is designed to be straightforward. A mounting template and clear instructions are included in the package.
- Attach Brackets to TV: Secure the vertical TV brackets to the back of your television using the appropriate screws, washers, and spacers from the hardware kit. Ensure the brackets are centered and level.
- Attach Wall Plate: Locate and mark the desired mounting position on your wall. Use a stud finder for wood studs or appropriate drilling techniques for concrete/brick. Secure the wall plate firmly to the wall using the provided lag bolts and washers. Use the included bubble level to ensure the wall plate is perfectly horizontal.
- Hang the TV: With assistance, carefully lift the TV and hook the attached brackets onto the wall plate. Ensure the TV is securely seated on the mount. Tighten any safety screws or locking mechanisms on the brackets to prevent accidental dislodging.

Your monTEK Long Arm TV Wall Mount offers flexible adjustments for optimal viewing.
6.1 Extension and Retraction
The mount can extend up to 42 inches (106.7 cm) from the wall, allowing for versatile positioning. To extend, gently pull the TV forward. To retract, push the TV back towards the wall until it reaches its minimum distance of 2.4 inches (6.1 cm).

The articulating arm allows for a 180° swivel range, enabling you to adjust the TV's horizontal viewing angle to suit different seating positions in the room.

6.3 Tilt Adjustment
Adjust the vertical tilt from +5° (upward) to -10° (downward) to reduce glare from lights or windows and achieve a comfortable viewing angle.

6.4 Post-Installation Leveling
After the TV is mounted, you can make fine-tune level adjustments of ±3° to ensure the screen is perfectly horizontal.

6.5 Cable Management
Utilize the integrated cable management features, such as the included Velcro ties, to organize and conceal wires for a tidy appearance and to prevent tangling.
