Sennheiser HDR-170 user manual

There can be several reasons why your Sennheiser headphones may not be pairing with your device. Here are a few troubleshooting steps you can take:
1. Ensure Your Device is Bluetooth Compatible: Check your device to make sure it is Bluetooth compatible. Most modern devices come with built-in Bluetooth but check just in case.
2. Check If Your Bluetooth Is Turned On: Make sure the Bluetooth function is turned on in the device you are trying to pair with your Sennheiser headphones.
3. Make Sure Your Headphones Are in Pairing Mode: The headphones should be in pairing mode to get connected to another device. You can usually do this by pressing or holding certain buttons on the headphones. Check the user manual for details on how to do this.
4. Clear the Headphone’s Memory of Past Devices: Sometimes, your headset might not connect because it remembers being paired with other devices. You can usually fix this by clearing the memory of past paired devices.
5. Reset your headphones: Consult your user manual for the proper reset procedure for your model of headphones. Typically, this involves holding down certain buttons for a specific period of time.
6. Check the distance: Bluetooth devices need to be close to each other to connect. Try moving your headphones closer to your device.
7. Update your device: Sometimes, a software or a firmware update is needed for Bluetooth devices to work correctly.
If none of these solutions work, it might be a good idea to contact Sennheiser customer support as there might be a problem with the headphones itself.

To set up your Sennheiser HDR-170 headset, follow these steps:
1. Connect the audio transmitter to your audio source (TV, computer, etc.). The transmitter should be connected using either analog RCA cables, digital optical cables, or a 3.5mm stereo cable depending on the available connections.
. Ensure your audio source is set to the correct output mode for the cables you're using (analog, digital, or headphone out).
3. Power on the HDR-170 headset by sliding the power switch to the "on" position.
4. On the audio transmitter, locate the power button and turn it on.
5. On the HDR-170 headset, press and hold the "scan" button for about 2 seconds until the green LED starts flashing quickly. This puts the headset in pairing mode.
6. On the audio transmitter, press and hold the "pairing" or "connect" button until the LED indicator starts flashing.
7. The LED on the headset should stop flashing and remain solid when the connection is successful.
8. Adjust the volume on both the audio source and the headset to a comfortable level.
Your Sennheiser HDR-170 headset should now be set up and ready to use. If you're experiencing any issues, consult the product manual or contact Sennheiser customer support for further assistance.

There can be various reasons why your Sennheiser headphones might not be working. Here are a few troubleshooting steps you can try:
1. Check the connection: Ensure that the headphones are properly connected to the audio source. If they are wired headphones, ensure the cable is securely plugged in. If they are wireless headphones, make sure they are in pairing mode and connected to the correct device.
2. Test with another device: Try connecting the headphones to a different device to see if the issue is with your audio source. If they work fine with another device, the problem might be specific to your original device.
3. Check audio settings: Verify that the audio settings on your device are configured correctly. Ensure that the headphone output is enabled and the volume is turned up.
4. Battery level (if applicable): If you are using wireless headphones, check if the battery is sufficiently charged. Low battery levels can cause headphones to malfunction or not work at all.
5. Update firmware/drivers: Visit the Sennheiser website and check if there are any firmware updates or driver updates available for your headphones. Installing the latest software can often resolve compatibility issues.
6. Physical damage: Inspect the headphones for any signs of physical damage, such as frayed cables, loose connections, or broken parts. If you find any, it might be necessary to repair or replace the headphones.
If none of the above steps solve the issue, it could be a more serious problem, and it may be best to contact Sennheiser's customer support for further assistance.
