Frequently Asked Questions

Q: What kind of audio input does the unit take as an input to the audio output?

A: The unit has an available AUX input socket for connecting external audio devices.

Q: How to set the time on this device?

A: Press CLK, then hold it down for 2 or more seconds, to set the time, use VTUNE or ATUNE to set the hours and setting minutes, press CLK once again.

Q: Length of usage of powder tweaking if CD play does not play?

A: Ensure the CD is placed well with the label going on top, clean the CD once, make sure the power unit is connected.

Q: Is there a way I can configure the device so the sound quality meets my standards?

A: Yes. You can choose the required audio adjustment mode (Volume, Bass, Treble, Balance, Fader) by pressing the SEL button twice and then using either VOLA or VOLV to set the adjustment level.

Q: Is it possible to link a CD changer to this device?

A: Yes, the device interfaces with an additional CD changer (only for CQ-DP745EUC).

Q: What approach should be used in the event that the radio can barely receive the signal?

A: Ensure that the antenna is connected correctly and try to take a position that is away from the interference source that radio waves may have high power transmission lines.
