2. Càraid Bluetooth

Once powered on, the amplifier will enter Bluetooth pairing mode. The Bluetooth indicator LED (as shown in the connection diagram) will flash. On your audio device (e.g., smartphone), search for Bluetooth devices and select "ZK-502L" to pair. Once successfully paired, the Bluetooth indicator will remain solid.

3. Cleachdadh Cuir-a-steach AUX

If an AUX cable is connected to the 3.5mm jack, the amplifier will automatically prioritize and switch to AUX input. To revert to Bluetooth mode, simply disconnect the AUX cable.

Cumail suas

• Cùm an amplifier board clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid exposing the board to moisture, liquids, or extreme temperatures.
• Dèan cinnteach gu bheil fionnarachadh ceart timcheall an taighe amplifier to prevent overheating, especially during high-power operation.
• Do not attempt to modify the circuit or components, as this may damage the device and void any potential warranty.

Gun Fhuaim

• Check all power and speaker connections for secure contact and correct polarity.
• Dèan cinnteach gu bheil an solar cumhachd voltage is within the 5-24V range and provides sufficient current.
• Verify the audio source is playing and the volume is turned up on both the source and the amplosgadair.
• Confirm Bluetooth is paired correctly or the AUX cable is fully inserted.

Fuaim Sgaraichte

• Lùghdaich an tomhas-lìonaidh air an dà chuid ampan lifer agus an stòr claisneachd.
• Check speaker impedance; ensure it is within the 4Ω-8Ω range.
• Verify the power supply is stable and provides adequate power for the connected speakers.

Cùisean Ceangal Bluetooth

• Dèan cinnteach gu bheil an amplifier is in pairing mode (flashing Bluetooth indicator LED).
• Gluais an inneal agad nas fhaisge air an amplifier (within 15m unobstructed).
• Try unpairing and re-pairing the device from your audio source's Bluetooth settings.
• Dèan cinnteach nach eil innealan eile ceangailte gu gnìomhach ris an amplosgadair.

Overheating

• Dèan cinnteach gu bheil fionnarachadh gu leòr timcheall air ampbòrd-beatha.
• Check if the speaker impedance is too low or if the power supply voltage is too high for the connected speakers, causing excessive load. The board has self-recovery overheating protection, but continuous overheating should be avoided.
