To set the clock on your Sony CMT-EP303, press the 'CLOCK/TIMER SET' button. Use the tuning buttons to set the hour, then press 'ENTER'. Repeat for the minutes and press 'ENTER' to confirm.
Ensure the unit is plugged in and powered on. If the tray still doesn't open, try pressing the 'OPEN/CLOSE' button while gently pulling the tray. If it remains stuck, there may be a mechanical issue requiring service.
Check if the speakers are properly connected to the system. Ensure the volume is turned up and no headphones are plugged in, as this mutes the speakers. Also, confirm the correct input source is selected.
To improve FM radio reception on the Sony CMT-EP303, ensure the FM antenna is fully extended and positioned away from any electronic devices. Reposition the antenna for the best signal or consider using an external FM antenna.
The Sony CMT-EP303 does not support direct smartphone connections via Bluetooth or USB. However, you can connect your smartphone using an auxiliary cable via the 'AUDIO IN' jack.
To clean the CD player lens, use a commercial lens cleaner disc available from electronics retailers. Do not attempt to clean the lens manually as it may cause damage.
Check that the power cord is securely connected to both the wall outlet and the system. Ensure the outlet is working by testing with another device. If the problem persists, the unit may require servicing.
To reset the Sony CMT-EP303, unplug the power cord for a few minutes. Reconnect the power cord and press the 'POWER' button while holding the 'STOP' button until 'RESET' appears on the display.
Ensure the unit is not exposed to direct sunlight or strong lighting, as this can affect the display visibility. If the display is dim, adjust the brightness settings or perform a reset.
To preset radio stations, tune to the desired station. Press and hold the 'TUNER MEMORY' button until a preset number appears. Use the tuning buttons to select the preset number, then press 'ENTER' to save.
