3.2 ການຕິດຕັ້ງ
The compact design of the OLH28C allows for flexible mounting. Secure the unit in a dry location, away from excessive heat or moisture, using appropriate fasteners. Ensure wires are not pinched or strained.
4. ຄໍາແນະນໍາການດໍາເນີນງານ
Once properly installed and wired, the Orion OLH28C operates automatically. When the vehicle's ignition is turned on, the converter will receive power and generate a remote turn-on signal for your amplifier. Audio signals from the factory head unit will be converted and passed to the amplifier. No user adjustments are typically required for basic operation.
5. ບໍາລຸງຮັກສາ
The Orion OLH28C requires minimal maintenance. Periodically check all wiring connections to ensure they are secure and free from corrosion. Keep the unit clean and free of dust and debris. Avoid exposing the unit to extreme temperatures or moisture.
6. ການແກ້ໄຂບັນຫາ
- ບໍ່ມີສຽງ:
- Verify all power (V+), ground (GND), and remote (REM) connections are secure and receiving proper voltage.
- Check high-level input wires from the factory head unit for proper connection and signal.
- Ensure RCA cables are correctly connected between the converter and the ampມີຊີວິດຊີວາ.
- ຢືນຢັນ amplifier ເປີດແລະເຮັດວຽກຢ່າງຖືກຕ້ອງ.
- ສຽງບິດເບືອນ:
- Check all wiring for loose connections or shorts.
- Ensure the high-level input signals are not excessively strong, which could cause clipping.
- ກວດສອບ amplifier's gain settings are properly adjusted and not set too high.
- Amplifier Not Turning On:
- Check the remote (REM) wire connection from the OLH28C to the ampມີຊີວິດຊີວາ.
- Ensure the OLH28C is receiving power (V+ and GND).
