Original BAR500MK2 subwoofer is safely powered but not connected; current partner state known.
Connection scope: Device controls / power only. Symptom: Stereo or party speaker linking isn’t working.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is this the original BAR500MK2 SUB with its connection LED not solid white while the soundbar is awake?
Amber in normal standby or another subwoofer model is not this known unlinked state.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is the original partner safely installed/powered and its rear pairing control identifiable from the exact diagram?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Hold the subwoofer rear pairing control until its indicator flashes fast white
Use the actual pairing control; stop if the observed state differs.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Hold BASS on the supplied soundbar remote for more than three seconds, then press minus
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-4
Hold BASS on the supplied soundbar remote for more than three seconds, then press minus
This single documented pairing-entry sequence is not the bar factory-reset combination.
