Add or Replace Trackers

Applies when adding extra points, replacing a single tracker, or reconfiguring after the receiver pairing records have been cleared.

Before You Start

1. Note down the current tracker, receiver and firmware versions.
2. Confirm the new devices are compatible with your existing trackers, receiver and firmware.
3. Close SlimeVR first, and keep the receiver with its antenna attached and connected to the computer.
4. Do not hold the receiver SWO button when the cause is unclear — doing so clears all paired device records.

Re-Pairing

1. Power on the tracker you want to add and keep it close to the receiver.
2. Put the receiver into pairing mode: quick-press SWO 3 times on the receiver to enter pairing mode; quick-press twice to exit.
3. Put the tracker into a pairable state: quick-press SW0 3 times on the tracker you want to add (or on the charging dock) to reset that tracker's wireless pairing.
4. Wait for pairing to finish, restart SlimeVR, and check whether the device appears in the tracker list.
5. Repeat the steps for each device you need to add; do not repeatedly clear the receiver pairing records.

Pairing-mode indicator lights

While in pairing mode, both the receiver and the tracker show a blinking blue light to indicate they are waiting to pair (the tracker blinks once per second). Once pairing completes, the tracker light switches to green blinking quickly 4 times. Keep the tracker close to the receiver during pairing.

Contact support if unsure

Indicator-light behavior can differ across hardware and firmware. If pairing fails, do not repeatedly clear the receiver records — note the current state and contact support.

Required After Completing

1. Assign the new device to the correct body part in SlimeVR.
2. Secure the tracker following Assembly & Wearing and confirm its orientation matches other points of the same type.
3. Complete the full reset and wearing calibration in Device Calibration.
4. After putting on the headset and entering VRChat, check the model skeleton and tracker positions following VRChat Setup.
