Operating Instructions

Once installed, the Blaupunkt GTS655M speakers operate as part of your car's audio system. There are no direct controls on the speakers themselves.

• Audio Source: Play audio through your car's head unit (radio, CD player, media player).
• Volume Control: Adjust the volume using your car's head unit or steering wheel controls.
• Tone Adjustments: Use your head unit's equalizer, bass, treble, and balance/fader controls to customize the sound to your preference.
• Break-in Period: Allow a short break-in period (approximately 10-20 hours of normal use) for the speaker components to loosen and achieve optimal sound performance. Avoid playing at maximum volume during this period.

Maintenance

Minimal maintenance is required for your Blaupunkt GTS655M speakers:

• Cleaning: Gently wipe the speaker grilles and surrounds with a soft, dry cloth to remove dust. Do not use harsh chemicals or abrasive cleaners.
• Inspection: Periodically check speaker connections for tightness and ensure no wires are frayed or exposed.
