Work through these checks
Pair through the cradle
Ready system: hold cradle Bluetooth 5 seconds until two beeps; blue/orange flashing is discovery. Put the headset in its own pairing mode. Success changes the cradle light to half-bright blue. Keep other headsets off while pairing.
What the result means: Holding 10 seconds clears all stored devices; do not use that as pairing.
Check the privacy handset
Lifted privacy handset takes priority. Return it to its cup to route an ongoing Bluetooth call back to the headset. A ringing dock does not tell you which device carries answered audio.
What the result means: Park safely. End calls before pairing. Do not clear stored devices, change firmware or rewire the installed system as a first test.
Read mute and earpiece state
During a call, red Mute means your uplink is muted; one Mute press exits. Flashing orange Mute indicates Earpiece-Jack Mode: one Mute press returns to Bluetooth. Outside a call, Mute changes ringer volume instead.
What the result means: Record lights, active call state and which accessory hears audio for support.
When to stop and get help
Park safely. End calls before pairing. Do not clear stored devices, change firmware or rewire the installed system as a first test.
