The core function of the CAD-375 is to play audio from multiple sources. It supports traditional CD formats (CD, CDR, CDRW) as well as modern digital audio files (MP3, WMA) from discs. The integrated PLL FM stereo radio allows you to tune into your favorite FM stations, enhanced by RDS (Radio Data System) features for additional information and functionalities.

Usage Features

Power On/Off: The unit can be turned on or off by pressing the power button. It also powers on by pressing any key, offering convenience.

Volume and Audio Controls: A central VOL knob allows for adjusting the volume. Pressing this knob briefly cycles through various audio functions, including BASS, TREBLE, BALANCE, and FADER. Once a function is selected, turning the VOL knob (right or left) adjusts its level.

DSP Controls: The unit offers Digital Signal Processing (DSP) controls, which can be accessed by pressing the VOL knob for more than 2 seconds. This allows you to select different sound presets like POP M, ROCK M, CLASS M, FLAT M, or turn DSP OFF.

Loudness Control: By pressing the VOL knob for more than 2 seconds, you can activate the LOUDNESS ON/OFF mode. When Loudness is ON, the bass and treble response will be boosted, enhancing the audio experience, especially at lower volumes.

ESP Mode: The Electronic Skip Protection (ESP) mode helps prevent audio interruptions caused by road bumps. You can select between 12-second or 45-second ESP modes by pressing the VOL knob for more than 2 seconds.

Beep Mode: The BEEP mode, activated by pressing the VOL knob for more than 2 seconds, allows you to turn the button beep sound ON or OFF. When BEEP ON is selected, a sound will be heard from the speaker whenever a button is pressed.

Radio Functions:

Band Selection: The BAND button cycles through FM1, FM2, and FM3 bands.
Automatic or Manual Tuning: The FREQ UP (►►) and FREQ DOWN (◄◄) buttons are used for tuning. A short press performs manual tuning, while a press longer than 1 second initiates seek tuning.
Auto Seek Search Tuning (AS/PS): Pressing AS/PS briefly searches for each preset station. Pressing it longer than 1 second automatically presets the 6 strongest stations to the corresponding preset numbers.
Scan Tuning (SCAN): The SCAN button initiates an automatic tuning control that holds on each detected station for 5 seconds before moving to the next.
Preset Stations: Six numbered buttons (1-6) allow you to store and recall your favorite radio stations.
Local/DX: This feature, accessed by pressing the VOL knob for more than 2 seconds, allows you to switch between "Local" and "Distant" reception modes. "Local" mode filters out weaker signals, stopping only at strong stations, while "Distant" mode allows listening to all stations, useful in areas with weak signals.
Stereo/Mono: For weak and disturbed FM stations, selecting "Mono" mode (accessed via the VOL knob for more than 2 seconds) can improve listening clarity.
RDS Features: The unit supports RDS, providing advanced radio functionalities:
- AF (Alternative Frequencies): When AF is active, the radio automatically switches to a stronger frequency for the same station if the current signal weakens.
- TA (Traffic Announcement): When TA is active, the unit will interrupt current audio playback to broadcast traffic announcements.
- PTY (Program Type): This function allows you to search for stations based on program type (e.g., NEWS, SPORTS, ROCK M).
- TA SEEK/TA ALARM: These modes, activated by pressing the VOL knob for more than 2 seconds, manage how the radio handles TP (Traffic Program) information. In TA seek mode, the radio retunes to a new station with TP information if the current one loses its signal. In TA alarm mode, only a beep sound is heard without automatic retuning.
- MASK DPI: This feature, also accessed via the VOL knob for more than 2 seconds, allows masking AFs that have different PI (Program Identification) or no RDS signal.
- RETUNE L/S: These controls, activated by pressing the VOL knob for more than 2 seconds, set the initial time for automatic TA search (90 seconds for RETUNE L, 30 seconds for RETUNE S).

CD/MP3/WMA Player Functions:

CD Slot: Insert discs into the CD slot for playback.
Eject Button: The EJECT button removes the CD from the slot.
Track/Search Buttons (►► / ◄◄):
