VDO Dayton CD 2737 B Telephone Mute, Brightness Control, Illumination Colour, Security LED

Telephone Mute

This headunit was designed to interface with dif- ferent types of hands-free kits that provide tel- ephone mute cables. Please read the instruction manual of your hands-free kit on its mute logic level (either mute-high or mute-low).

1.Navigate the SAM to select ‘TEL MUTE’.

2.Turn the knob clockwise / anti-clockwise to toggle the logic level according to your hands-free kit type.

Note: In the case that your headunit always remains in ‘TEL MUTE’ mode, that is, sound is muted, you can try to reverse the logic level (e.g. from ‘TELM HI’ to ‘TELM LO’). If this still does not work, perhaps your hands-free kit is not compatible with this headunit and it is best to turn the ‘TEL MUTE’ function to ‘TELM OFF’.

Brightness Control

This headunit comes with two levels of bright- ness level. To adjust the brightness:

1.Navigate the SAM to select ‘BRIGHTNESS’.

2.Turn the knob clockwise / anti-clockwise to select the brightness level.

Illumination Colour

To allow best integration into your car dash- board, the headunit comes with three types of colours scheme, namely Orange, Green or Mixed of Orange and Green. To change the illumination colour:

1.Navigate the SAM to select ‘COLOR’.

2.Turn the knob clockwise / anti-clockwise to select the colour scheme.

Security LED

The blinking security LED can deter potential theft of your headunit, even after your front panel is removed. However, if you wish to save your battery life, you can turn off this LED.

1.Navigate the SAM to select ‘LED’.

2.Turn the knob clockwise / anti-clockwise to turn on or off the blinking LED.

Speed Dependent Volume Control (SDVC)

To compensate for surrounding noise, this func- tion automatically increases the volume of the headunit with respect to the car’s speed. There are two compensation levels selectable from the SAM. Level 1 gives a smaller increase (in vol- ume) and level 2 gives a higher increase.

Calibration

CAUTION: To avoid unnecessary dis- traction, we advise that this procedure be carried out with the assistance of somebody else (front passenger).

1.While the car is stationary, press-and-hold both MUTEPWR and SOUND buttons at the same time.

2.The headunit will mute and show “RE-CALIB” and “50 KM/H” alternatively.

3.Within 30 seconds, drive your car to 50 km/h (about 30 mph).

Important note: Always obey the Highway Code and the current traffic restrictions and conditions!

4.Once the speed is reached, short-press the

ASTSAM button and you will hear a beep and the display will show “CALIB OK”.

5.Turn off and then turn on your headunit again and level 1 of the SDVC is automatically selected.

Note: This headunit’s SDVC works on frequen- cy-based signal (PCM) rather than on width- based signal (PWM). Some vehicles come with PWM signals and are therefore not compatible with this SDVC function.

Steering Wheel Remote Control (SWRC)

This headunit is specially designed with a pro- grammable Steering Wheel Remote Control (SWRC) to suit your car built-in SWRC as much as possible.

Important note: This function supports SWRCs that are based on analogue RC3-standard only. Other SWRCs, especially those based on CAN-bus, are not supported. For these SWRCs, please consult your dealer for a suitable con- verter, if available.

1.While the car is stationary, press-and-hold both MUTEPWR and SOURCE buttons at the same time.

2.The headunit will mute and show “PROG SWRC” for one second.

3.After that, the headunit will prompt you the first programmable function, that is, “VOL- UME-”.

4.Rotate the volume knob clockwise or anti- clockwise to navigate through the functions.

5.Match a suitable SWRC buttons (e.g. “VOL-” or “-”) with the one of the pre-defined func- tions that is displayed (e.g. “VOLUME-”)

by pressing and holding the corresponding SWRC button for more than 2 secs.

6.If the headunit recognizes the input as stable, it will capture the key-press input, give a con- firmation beep, and will show “PROG OK”.
