Onkyo TX-RZ70: pair an additional source without clearing saved devices
Onkyo TX-RZ70: pair an additional source without clearing saved devices. Check prerequisites and the actual response before reporting an outcome.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Additional phone/source, receiver already enabled and no live playback.
Connection scope: Bluetooth. Symptom: My devices won’t pair or reconnect.
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 Bluetooth already selected with receiver enabled, transmitter Off and no active source session?
Receiving phone audio differs from transmitting to headphones. Resolve an unknown live connection deliberately before this flow.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Is there known room below the eight-device pairing capacity?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-1
Is there known room below the eight-device pairing capacity?
No memory replacement behaviour is assumed here. Stop if full or unknown instead of clearing saved devices.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Are source and receiver listening levels initially low?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-2
Are source and receiver listening levels initially low?
The new connection may produce audio; no maximum-volume test.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Hold the documented remote Bluetooth pairing/info button for at least five seconds
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Hold the documented remote Bluetooth pairing/info button for at least five seconds
Identify that exact button in the model remote diagram first. Unknown button identity means stop, not try a reset combination.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Select this exact receiver entry on the source
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-4
Select this exact receiver entry on the source
Use its deliberate friendly name or the model name, with 0000 only if requested.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Does the source show the intended receiver connected?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-5
Does the source show the intended receiver connected?
Discovery alone is not music playback. Do not escalate to deleting receiver or phone pairings.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Checks completed — report what happened
- If No / cannot confirm → Keep these observations for official support

Possible result
Checks completed — report what happened
Completion is not an automatic solved result. Report solved, partly helped, did not help or could not follow based on your actual observation. No Audio Review physical test is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Keep these observations for official support
A required prerequisite or response was not confirmed. Stop this sequence and use the exact model and partner documentation. Do not escalate to a factory reset, firmware installation, internal repair or unsafe wiring change.
next support
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
A required fact is unknown
Confirm the exact model, connection, partner capability and current control state before continuing. Do not guess settings or operate an updating product.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
