Frequently Asked Questions - KW-14 Kramer

Why did my registration fail?

Ensure that both units are powered on and no other Kramer devices are active. Keep transmitter and receiver at least 2m (6ft) apart and minimize obstructions. If still failing, reduce distance or power cycle both devices.

Why is there no signal on my display?

Check that the receiver and display are powered on and properly connected via HDMI. Ensure the display is set to the correct HDMI input. Try disconnecting and reconnecting the HDMI cable, or replace it. Also verify that the video resolution is supported by the display.

Why is the OSD not displayed?

Set the display resolution to 1080p. Ensure the link is active (not in standby) and a valid video source is connected. If OSD still doesn't appear, power cycle the devices.

Why is there no audio?

Check the mute and volume settings on the display. Verify that the audio format from the source (e.g., PCM, Dolby) is compatible with the KW-14 system. The KW-14 supports PCM, Dolby Digital, and DTS formats.

Why does the IR remote control not work?

Remove the clear plastic film covering the battery contacts. Ensure batteries are fresh and installed correctly. Keep the remote within 9m (30ft) and within 40° angle of the receiver's IR sensor. Avoid interference from fluorescent lights.

Why do I get a "Searching..." message and the Link LED flashes?

The KW-14 can take up to 60 seconds to establish a wireless link. If it takes longer, verify the transmitter is powered on and not already connected to another receiver. Power cycle both units if needed.

Why does a connection failure message appear and "Wireless off" is displayed?

If multiple transmitters are registered and the receiver fails to connect within 1-2 minutes, it enters standby mode. Press the Source button on the IR remote and select the desired transmitter from the OSD menu.

Why is the audio or video quality poor?

Decrease the distance between transmitter and receiver (but keep at least 2m apart) and remove obstructions like walls or furniture. Ensure the units are not too close to other wireless devices operating in the 5GHz band.

Why is there abnormal color or noise on the display?

Disconnect and reconnect the HDMI cables at both ends. Move the transmitter and receiver closer together (but not less than 2m). Power cycle both units or reset the transmitter using the Reset button.

Can I connect multiple receivers to one transmitter?

Yes, you can register up to four receivers to a single transmitter. Registration can be done using the front panel buttons or the IR remote control. When registering multiple receivers, separate them by at least 2m.

Q: Why does the IR remote control not work?

A: Ensure that the clear plastic film covering the battery contacts is removed before using the IR remote control.

A: Ensure that the IR remote control batteries are fully charged.

A: Ensure that there is enough distance between the receiver IR sensor and any fluorescent lights or radiation that could interfere with the IR signal.

Q: Why do I get a "Searching ..." message and the Link LED is flashing?

A: The KW-14 can take up to 60 seconds to establish a wireless link. If the wireless link is not established within 60 seconds, verify that the transmitter is powered on and not connected to another receiver.

Q: Why do I get a "Connected to source name, please check video source" message?

A: Check the HDMI connection between the transmitter and the video source.

Q: Why is the message "Please wait, this action may take up to 60 seconds" displayed for more than 60 seconds?

A: This message may appear during the registration process. If the message appears for more than 60 seconds, power-cycle both units, then restart the registration process.

A: Power-cycle the receiver and transmitter. You can also reset the transmitter by pressing the Reset button.

Q: Why does a connection failure message appear and the message "Wireless off" is displayed?

A: If more than one registered transmitter is present and the receiver fails to connect with a transmitter within one to two minutes, the receiver goes into standby mode and shuts down the radio frequency transmission. To connect to the required source, press the Source button on the IR remote control and select the required source from the OSD menu.

Q: Why can my devices not establish a link, or the audio or video quality is poor?

A: Decrease the distance between the transmitter and receiver units, but not to less than 2m (6ft), and remove any obstructions between them.
