The unit provides 4 x 45W Hi-Fi speaker output and includes RCA outputs for connecting an external amplifier or active subwoofer.
Safety and Installation
Important: Installation must be performed by a qualified specialist. Before starting, disconnect the vehicle battery's negative terminal to prevent short circuits. Ensure the unit is installed in a location that does not obstruct safe vehicle operation. Do not connect speaker wires to the vehicle chassis or ground. Ensure proper ventilation around the unit to prevent overheating. The device is designed for use in temperatures between 0°C and +40°C.
Operation
Use the rotary knob to adjust volume and navigate menu settings (bass, treble, balance, loudness, EQ). The unit automatically detects and plays music when a USB or SD device is inserted. Use the MOD button to switch between radio, USB/SD, BT, and AUX modes. The radio features both automatic and manual tuning for FM stations.
Maintenance and Troubleshooting
Clean the unit with a soft, dry cloth and brush; do not use cleaning agents or liquids. If the unit malfunctions, press the RESET button on the front panel with a thin, pointed object for 2 seconds. If the radio fails to power on, check the fuse (10A) and the wiring connections (red for ignition, yellow for constant battery memory). For radio reception issues, ensure the antenna is fully extended and properly connected.
