This document provides essential instructions for the installation and operation of the SAL VBT 1100/BL and VBT 1100/RD car radio. The device is designed for 12V vehicles with a negative ground system. Before installation, ensure the vehicle's negative battery terminal is disconnected to prevent short circuits.
Installation and Wiring
Installation should be performed by a qualified professional. Ensure the unit is not exposed to direct heat, moisture, or excessive dust. Route cables at least 10 cm away from the vehicle's instrument panel wiring harness. Connect the power and speaker cables according to the provided wiring diagram. Do not connect speaker wires to the vehicle's chassis or negative ground.
Controls and Operation
The front panel features a rotary knob for volume and menu navigation. Use the POWER button to turn the unit on or off. The MOD button allows you to switch between FM radio, USB/SD playback, Bluetooth, and AUX input. The unit supports 18 FM radio presets.
Bluetooth Functions
To pair your device, select BT mode using the MOD button. Search for the car radio on your mobile device and connect. Once paired, you can stream music (A2DP) and handle hands-free phone calls. The radio has a built-in microphone; speak towards the upper right corner of the unit for best results.
USB and SD Playback
Insert a USB or SD memory device (FAT32 format recommended) to start playback automatically. Use the playback controls to skip tracks, fast forward/rewind, or navigate folders. Do not remove the memory device while playback is in progress.
Maintenance and Safety
Clean the unit with a soft, dry cloth. Do not use cleaning agents or liquids. The remote control uses a CR2025 3V button battery. Keep batteries out of reach of children due to the risk of chemical burns if swallowed.
