Exact iFi ZEN CAN 3. ZEN CAN3 is in its normal soft-off state and the existing supply is intact. This does not install or substitute power equipment.
Connection scope: Device controls / power only. Symptom: Power-on or automatic standby 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 scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
scope
Confirm the model and connection
ZEN CAN3 is in its normal soft-off state and the existing supply is intact. This does not install or substitute power equipment.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Confirm normal existing supply
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required
