Receivers and transmitters

The receiver power can’t be turned on (in the case of ESW-R4180LK)

Make sure that the network A port on the rear of the receiver is connected to the mixer or extender via a LAN cable (Cat. 5e or higher, shielded cable with conductor size of 24AWG or greater in diameter).
Make sure that the mixer or extender is operating properly.

The receiver power can’t be turned on (in the case of ESW-R4180DAN)

Make sure that the network A port on the rear of the receiver is connected to a PoE-compatible switching hub via a LAN cable (Cat. 5e or higher, shielded cable with conductor size of 24AWG or greater in diameter).
Make sure that the PoE-compatible switching hub is operating properly.

The transmitter power can’t be turned on

The receiver can’t be identified by Dante Controller (ESW-R4180DAN only)

Make sure that “Device Setting” -> “Dante” -> “Dante IP Setting” -> “IP Mode” is set correctly in Wireless Manager.
Make sure that the Dante audio device connected to the network A port on the rear of the receiver and the Dante device to connect to are both connected to the same network.

The receiver and transmitter can’t be linked

Make sure that the transmitter is registered to the same system as the receiver on the “Link Configuration” screen in Wireless Manager. If these devices still cannot be linked even when registered to the same system, clicking “Refresh Link Setting” may solve the problem.
Make sure that the number of transmitters used is less than the number of usable transmitters indicated with “Tools” -> “DECT RF Scan” in Wireless Manager.

Even though a link has been configured, the receiver and transmitter cannot be connected or their connection is repeatedly terminated

The receiver and transmitter encryption keys may be mismatched due to an irregularly performed link configuration. Place all the transmitters registered to the receiver in a charging station, synchronize the receiver and all the transmitters to Wireless Manager, and then click “Refresh Link Setting” in the link configuration. The devices will be registered again. Encryption key mismatches may occur when:
(1) The link configuration is edited for a transmitter with an existing link without placing the transmitter in an online charging station.
(2) The same receiver and transmitter are registered again to a new link configuration.

There is no audio/the audio level is low

Make sure that the transmitter is on.
Make sure that the transmitter is not muted.
Make sure that the transmitter and microphone are connected properly.
Make sure that the receiver is not muted.
Make sure that the registered channel of the receiver and transmitter is the same.
Make sure that the transmitter’s gain isn’t too low.
Make sure that the receiver’s volume isn’t too low.
If using the mix out, make sure that the mix assignments have been set properly.
Make sure that the network A port on the rear of the receiver is connected to the mixer or extender via a LAN cable (Cat. 5e or higher, shielded cable with conductor size of 24AWG or greater in diameter) (in the case of ESW-R4180LK).
Make sure that the network A port on the rear of the receiver is connected to a PoE-compatible switching hub via a LAN cable (Cat. 5e or higher, shielded cable with conductor size of 24AWG or greater in diameter) (in the case of ESW-R4180DAN).
Use Dante Controller to make sure the receiver output (Dante transmitter) is routed properly to the Dante receiver device that is the output destination (ESW-R4180DAN only).

Sound is distorted

Sound is interrupted

Make sure that the transmitter and microphone are connected properly.
Make sure that the RF power isn’t too low.
Make sure that the number of transmitters used is less than the number of usable transmitters indicated with “Tools” -> “DECT RF Scan” in Wireless Manager.

There is unwanted noise

Make sure that the transmitter and microphone are connected properly.
Make sure that the RF power isn’t too low.
Make sure that the connected external microphone isn’t too close to the transmitter antenna.

Receiver indicator lamps do not light

Make sure that “Device Setting” -> “System” -> “LED” is not set to OFF in Wireless Manager.

The transmitter indicator lamp does not light

Make sure that “Device Setting” -> “Mute” -> “Mute LED Color”/“Unmute LED Color” is not set to OFF in Wireless Manager (ESW-T4106/ESW-T4107 only).

The status indicator lamp flashes

Error displays and other such statuses are indicated with the colors of the indicator lamps and the way it flashes. Refer to Indicator lamp displays for details.
