There are up to seven different types of fasteners used during this build. This diagram can be referenced to confirm that you are using the correct ones. Use the included H1.5 hex bit for M2 fasteners and H2.0 bit for M2.5/M3 fasteners.

• Do not skip this step; we cannot guarantee a replacement PCB that was not tested prior to assembly.

• Open VIA, navigate to the Key Tester tab, and enable Test Matrix mode.

• Place the PCB facedown, connect the daughterboard to the PCB, and plug it in.

• Touch the ends of your tweezers to the metal contacts under each switch position, lighting up each key in VIA. Note that the function key may not light up.

• In the rare event that keys do not light up, pause your build here and contact support@modedesigns.com.

• If you plan to use the optional PE foam, lay it on top of the PCB now (foam kit sold separately).

• Stabilizers ensure that long keys actuate properly, no matter where you press. The stabilizer wire you need for the spacebar will depend on your choice of layout.

• Insert the non-threaded end of the stabilizer into the larger cutout on the PCB, then pivot the threaded ends into place.

• Ensure that your stabilizers are completely flat on the PCB before screwing them in.

• While bracing the front of each stabilizer, screw it into place from the underside of the PCB. Repeat for the remaining stabilizers.

• Remove the mylar standoff covers (the plastic orange circle on top of the standoffs)

• If you plan to use the optional plate foam for a more dampened sound, lay it on top of the PCB now.

• Align the plate with the front of the PCB, and fasten it into place with the M2x5 flat head fasteners (four total).

• Before installing your switches, inspect them to ensure the two metal pins on the underside of each switch are straight. Straighten all pins with tweezers if any are bent.

• Insert switches into the plate/PCB. Take care to brace the back of the hotswap socket with a finger while pushing the switches into place with your thumb. Do not apply downward pressure to the surface of the plate itself.

• If you have a solder PCB, solder your switches now.

• If you are using a softer plate material such as Nylon, PP, Pom, or PC, ensure switches are fully seated. We recommend using the screwdriver to carefully lift the plate while pressing down on the switch to ensure the switch is seated flat on the plate.

• Install your first few switches around the plate as shown, this will help ensure the plate stays aligned during the installation process.

• Install remaining switches, working your way in from the corner switches.

• Switches that are not properly installed can cause alignment issues when the case is closed.

• Check that the plate is not sagging below the tops of the switches.

• Check that each switch pin is fully seated into the PCB.

• Align one end of the foot in one corner of the recessed channel, then gently lower the strip into place. Take care not to stretch the foot.

• Press on the feet to ensure they are properly adhered, smoothing out any raised areas.

• The Sonnet ships with the top case and bottom case pre-assembled.

• Carefully place the Sonnet facedown.

• Use the provided H2.0 hex bit to remove the case fasteners and separate the bottom case from the top case.

• Gently lower the accent into the recess in the top case.

• Flip the top case over, supporting the accent from the top side. Screw in the accent to the top case using the M2x10 fasteners (four total).

• Slide your preferred mounting block into the plate tabs (5 total), the lattice side should be facing the bottom of the PCB. Note that each type of lattice block comes with 3 rectangular blocks for the top of the PCB and 2 curved blocks for the bottom.

• You can mix and match or swap these blocks to fine tune your typing experience.

• Insert the assembly into the top case, starting with the bottom, followed by the top.

• Slide the top mount blocks into the recesses of the top case (5 total). Note that there are 3 rectangular blocks for the top of the board and 2 curved blocks for the bottom.

• Insert the assembly into the top case, aligning the plate tab holes with the blocks, starting with the bottom, followed by the top. Secure the assembly with the M2x5 fasteners (5 total).

• If you plan to use the optional case foam for a more dampened sound, lay it in your bottom case now.

• Connect the daughterboard cable to the daughterboard, fasten it into the bottom case using the M2x4 fasteners (four total) with the USB-C port facing downwards.

• Take care to not overtighten the fasteners, or you may damage the daughterboard or case.

• Gently lower the internal weight into the recess in the bottom case.

• Secure the weight to the bottom case using the M3x5 flat head fasteners (two total).

• Hold the bottom case firmly in one hand and align it with the notch on the bottom edge of the top case.

• While still holding the bottom case, use your other hand to attach the daughterboard cable to the PCB.

• Check the orientation of the daughterboard cable and ensure that it is fully plugged in. It should not come loose if inserted properly.

• Close the bottom case onto the top case, ensuring that the cable sits inside the recessed area of the bottom case.

• With the bottom of the board facing upwards, fasten the top case to the bottom case with the M2.5x12 fasteners (two total).

• Install your MX-compatible keycaps.

• Test the stabilized keys for any undesired rattling noises.

• If rattle is detected, lift the corresponding stem up and inject lube into the slider around the ends of the stabilizer wires.

• If you are using your Sonnet with a Mac, switch the Command and Option key positions in System Preferences. You will only need to do this one time, and the positions will be correct for both Mac and PC usage.

• The Sonnet is fully compatible with VIA and QMK. You can use the graphical interface of VIA to program any of the keys or layers on the Sonnet.

• If using QMK, you may enter bootloader mode by pressing the physical reset button on the board or pressing Fn + Esc.

• If any of the keys do not actuate properly, it may be due to a bent switch pin during installation. Remove that keycap and switch using a keycap/switch puller. If any metal pins are bent, straighten them with a pair of tweezers.
