Leiðbeiningar um uppsetningu og samsetningu

Follow these steps carefully to assemble your Bluetooth speaker. No soldering is required.

1. Understand Speaker Function: Familiarize yourself with how a speaker converts electrical signals into sound waves using magnets. This kit provides a practical demonstration of this principle.
   

   Figure 2: Basic principle of speaker operation involving magnets.

2. Prepare Wooden Panels: Carefully detach all wooden panels from their frames. Identify the front panel (with two large speaker holes), side panels, top panel (with switch hole), bottom panel, and back panel (with battery holder cutout).
3. Setja upp hátalara: Secure the two speakers to the front wooden panel using the provided screws. Ensure the speaker wires are facing inwards.
   

   Figure 3: Attaching speakers to the front panel of the wooden enclosure.

4. Connect Speaker Wires to AmpLifier stjórn: Connect the wires from each speaker to the designated terminals on the Bluetooth amplifier board. The kit uses simple plug-and-play connectors. Refer to the wiring diagram for correct polarity (red to positive, black to negative).
   

   Figure 4: Wiring diagram for connecting speakers, amplifier, battery, and switch.
5. Install Power Switch: Insert the power switch into the designated slot on the top wooden panel. Connect the switch wires to the amplifier board as shown in the wiring diagram.
6. Connect Battery Holder: Connect the battery holder wires to the power input terminals on the amplifier board. Ensure correct polarity. The red wire connects to the positive terminal, and the black wire connects to the negative terminal.
7. Assemble Enclosure: Carefully fit the wooden panels together. The panels are designed to interlock. Secure the battery holder in its designated slot on the back panel.
8. Settu rafhlöður í: Insert 4 AA batteries (not included) into the battery holder. Ensure correct orientation (+/-).

Notkunarleiðbeiningar

1. Kveikt á: Flip the power switch to the 'ON' position. You should hear an audible confirmation tone indicating the speaker is powered on and ready for pairing.
2. Bluetooth-parun:
   • Farðu í Bluetooth-stillingarnar í snjalltækinu þínu (snjallsíma, spjaldtölvu o.s.frv.).
   • Gakktu úr skugga um að Bluetooth sé virkt.
   • Scan for available devices. The speaker will appear as a device named 'LY999' or similar.
   • Select the speaker to pair. A confirmation tone will sound upon successful pairing.
   

   Figure 6: Bluetooth pairing process with a mobile device.

3. Spila hljóð: Once paired, you can play audio from your device. The speaker will output the sound.
4. Hljóðstyrkur: Volume is controlled directly from your connected Bluetooth device. There are no physical volume controls on the speaker unit itself.
5. Slökkva á: Flip the power switch to the 'OFF' position to turn off the speaker.

Viðhald

• Þrif: Notið mjúkan, þurran klút til að þrífa ytra byrði hátalarans. Notið ekki fljótandi hreinsiefni eða slípiefni.
• Skipt um rafhlöðu: When sound quality degrades or the speaker fails to power on, replace the 4 AA batteries. Ensure the speaker is powered off before replacing batteries.
• Geymsla: Geymið hátalarann ​​á köldum, þurrum stað fjarri beinu sólarljósi og miklum hita.

Úrræðaleit

• Ekkert hljóð:
  • Gakktu úr skugga um að kveikt sé á hátalaranum.
  • Athugaðu rafhlöðuna og skiptu um ef þörf krefur.
  • Verify that the speaker is successfully paired with your device.
  • Hækkaðu hljóðstyrkinn á tengda tækinu þínu.
  • Check all internal wiring connections for looseness or incorrect polarity.
• Vandamál með Bluetooth-tengingu:
  • Ensure the speaker is within range of your device (typically up to 10 meters).
  • Turn off and on the speaker and your device's Bluetooth.
  • Forget the device on your phone's Bluetooth settings and re-pair.
• Bjagað hljóð:
  • Lækkaðu hljóðstyrkinn á tengda tækinu þínu.
