6. Řešení problémů

If you encounter issues with your August MR250, please refer to the following common solutions:

• No Sound / Cannot Pair:
  • Ensure the MR250 is fully charged and powered on.
  • Verify that your audio source (TV, MP3 player) is playing audio and its volume is turned up.
  • Confirm the 3.5mm audio cable is securely connected to both the MR250 and the audio source's output jack.
  • Make sure your Bluetooth headphones/speaker are in pairing mode and within range (typically within 10 meters).
  • Try restarting both the MR250 and your Bluetooth receiving device.
  • If previously paired, press the Reconnect button on the MR250 to initiate a new search.
• Sound Delay (Latency):
  • While the MR250 supports Bluetooth 5.2, some older Bluetooth headphones or speakers may introduce noticeable audio delay. This is often due to the codecs supported by the receiving device.
  • For optimal performance, use Bluetooth headphones/speakers that support low-latency codecs (e.g., aptX Low Latency), though the MR250 itself does not explicitly state aptX LL support in its specifications.

• Interference / Signal Drops:
  • Ensure there are no major obstructions (walls, large metal objects) between the MR250 and your Bluetooth receiving device.
  • Keep the MR250 away from other wireless devices (Wi-Fi routers, cordless phones) that might cause interference.
  • The effective range is approximately 10 meters (33 feet); moving closer may improve connection stability.
• Auto-Connect Issues:
  • Some users report that the MR250 may not always auto-connect to the last paired device. If this occurs, manually re-pair by pressing the Reconnect button on the MR250 and ensuring your Bluetooth device is in pairing mode.
