Frequently Asked Questions - MagicWatch MWE860 DOMETIC

How to install the detectors of the Dometic MagicWatch MWE860?

Drill 22 mm holes in the bumper at a distance of 50 cm from the ground. Insert the detectors, tilting them slightly downwards. Observe the 90° angle relative to the road. The top of the detector is marked with a ▲.

What is the detection range of the device?

The detection range extends from 0,40 m to 1,6 m behind the vehicle. It is divided into four zones with progressive audible alerts: zone 1, zone 2, zone 3 and stop zone (continuous signal).

Can I paint the detectors?

Yes, the detectors can be painted. The manufacturer recommends having the painting done in a specialized workshop to avoid affecting their operation.

How to adjust the sensitivity of the system?

Turn on the ignition, engage reverse gear. Press the button on the control electronics for less than two seconds. The speaker emits 1 beep (low sensitivity), 2 beeps (medium), or 3 beeps (high). Each press changes the sensitivity in that order.

What to do if the device does not work?

Check the connections of the power cables (black/blue and brown) and make sure the detector connectors are properly plugged into the control electronics. If a long signal sounds at startup, a detector may be defective.

How to suppress the display of a fixed object such as a towbar?

Turn on the ignition, engage reverse gear. Press the button for 2 to 4 seconds until a short beep. The system initializes the fixed object. After 3 seconds, disengage reverse gear to complete the setting.

How to restore factory settings?

Turn on the ignition and engage reverse gear. Press the button for more than 4 seconds. The speaker emits repeated beeps. Disengage and then re-engage reverse gear. Factory settings are restored.

The screen displays obstacles in the wrong direction, what to do?

Plug the detector connectors in reverse order on the control module: connector 1 to socket 4, 2 to 3, 3 to 2, 4 to 1.

What safety precautions should be observed during installation?

Secure the parts firmly so that they do not loosen during hard braking. Do not install anything in the airbag deployment zone. The device does not replace the driver's vigilance.

Can I install the system on a metal bumper?

No, the parking aid is not designed for mounting on a metal bumper. Use only plastic or composite bumpers.

4 Intended use

Magic Watch is an ultrasonic parking aid. It monitors space when manoeuvring

• MWE820, 860: behind the vehicle
• MWE890: in front of the vehicle

It provides an audible and visual warning signal for any obstacles it detects.

Magic Watch is designed for installation in cars.

5 Instructions before installation

5.1 Determining the place of installation for the sensors

See fig. 3 to fig. 6

NOTE

The sensors must be correctly aligned for the device to work properly. If these point to the ground, irregularities and bumps on the surface may be interpreted as obstacles. If they point too far up, obstacles will not be detected at all.

Note the following during installation:

• The distance from the sensors to the ground should be 50 cm (fig. 3).
• For the sensors to function optimally, the angle of the sensor to the road surface should be 90^ (fig. 3). The angle may not be less than 90^ , as the road will otherwise be interpreted by the sensor as an obstacle.
• Observe the positioning of the sensors (fig. 4).

5.2 Painting the sensors

See fig. 2

NOTE

The sensors may be painted. The manufacturer recommends having the sensors painted by a specialist workshop.

6 Fitting the parking aid

See fig. 7 to fig. 11

Supplementary to fig. 8

NOTICE! Risk of paint damage!

• The ambient temperature may not fall below 18 °C when punching or drilling.
• We recommend using a punching tool.
• Make sure that you do not tilt the punching tool when operating.

▶Deburr the drill holes.
For a more accurate fit, slant the drill downwards slightly on the inside of the bumper when drilling the hole. The sensor housing can now be easily inserted at a downward angle.

Supplementary to fig. 9

NOTICE! Risk of malfunction

Note that the sensors must be aligned in a particular direction. The top of the sensor is marked with an ▲.

7 Connecting the parking aid

NOTE

• MWE820, 860: On some vehicles, the reversing light only works when the ignition is switched on. In this case, you must switch on the ignition in order to identify the positive and earth wires.
• MWE890: If the speed signal has been connected to the control electronics, the sensors are automatically deactivated at a speed over approx. 15 km/h.
  The sensors are reactivated as soon as the speed falls below approx. 15 km/h.

9 Sensors

8 D e t e c t i o n

See fig. 14

The detection range of the parking aid is divided into four zones:

• Zone 1 (MWE820, 860 only)

This zone is the first limit range. Small objects or those with poor reflective characteristics may not be detected.

•Zone 2

Nearly all objects are displayed in this zone.

- Zone 3

Nearly all objects in this zone are displayed, however objects may only appear in the sensors' blind spot, or not be detected at all due to their consistency or small size.

- Stop zone (4)

If there are objects in this zone, the parking aid emits a continuous tone warning you to stop.

Nearly all objects in this zone are displayed, however objects may only appear in the sensors' blind spot or not be detected at all due to their consistency or small size.

Displaying fixed objects, such as a trailer hitch, can be suppressed.

9 Setting the system

There is a button (fig. 15 1) on the controller for setting the following parameter.

9.1 Setting the sensitivity

▶Switch on the ignition.
▶ Engage the reverse gear (MWE820, 860 only).
▶Press the button for not more than two seconds to set the sensitivity in the following sequence:

– Low sensitivity: the loudspeaker beeps once
– Medium sensitivity (standard): the loudspeaker beeps twice
– High sensitivity: the loudspeaker beeps three times

Pressing the button repeatedly changes the sensitivity in the above sequence.

9.2 Suppressing the display of fixed objects (such as trailer hitches) (MWE820, 860 only)

NOTICE!

Before making the setting, make sure that there are no additional objects in the stop zone, such as people or other vehicles.

▶Switch on the ignition.
▶Engage the reverse gear.
▶ Press the button for three seconds until the loudspeaker beeps briefly.
√The loudspeaker emits short beeps repeatedly.
√The system initialises the fixed object.
▶To end the setting, disengage the reverse gear after a period of at least three seconds.

9.3 Restoring the factory settings

MWE820, 860

▶Switch on the ignition.
▶Engage the reverse gear.
▶Press the button for longer than four seconds.
√The loudspeaker beeps repeatedly.
▶Disengage the reverse gear.
▶Engage the reverse gear again.
√The system has been reset to the default settings.

MWE890

NOTE

If the speedometer speed signal has been disconnected from the control electronics, the default settings must be restored to ensure that the sensors function correctly.

▶Switch on the ignition.
▶Press the button for longer than two seconds.
√The loudspeaker beeps repeatedly.
▶Let go of the button.
√The system has been reset to the default settings.

9.4 Reflecting the display (MWE860 only)

If the obstacles are shown the wrong way round on the display, proceed as follows:

▶Connect the sensor plugs into the sockets on the control module in the reverse order (1 → 4, 2 → 3, 3 → 2, 4 → 1).

10 Performing a functional test

To test the parking aid, drive towards something slowly such as a wall.

NOTICE!

Be very careful when you operate the device for the first time, and make sure that you familiarize yourself with the various sequences of beeps (fig. 14).

11 Using the parking aid

The rear sensors (MWE820, 860) are activated automatically by engaging the reverse gear with the ignition on or the engine running. The speaker will emit a double beep.

The front sensors (MWE 890) are automatically activated as soon as the ignition is switched on and the speed of the vehicle lies between 0 and around 15 km/h.

As an option, instead of being connected to the speed signal, the control electronics of the front sensors can be connected to the reversing light or an external switch.

NOTE

Before using either of these functions, hold down the button on the control electronics for 2 seconds (see chapter "Restoring the factory settings" on page 10).

The sensors are active in the following cases:

• For around 30 seconds after the motor is started
• When the reverse gear is engaged and the control electronics are connected to the reversing light
• For around 30 seconds after the reverse gear is disengaged
• The sensors can be activated with an external button (accessory) for a duration of around 30 seconds.

As soon as there is an obstacle within the detection range, a repeated signal tone is emitted.

As you approach, the tone sequence and the flashing frequency change, depending on the zone in which the obstacle is, thus indicating the distance (fig. 14).

MWE860 (optional MWE890): The nearer the obstacle gets, the more LEDs light up on the display.

NOTICE!

Stop the vehicle immediately and investigate the situation (getting out if necessary), if the following happens while you are manoeuvring: when manoeuvring, the device first indicates an obstacle and the tone sequence speeds up normally (e.g. from slow to medium). Suddenly the signal tone slows down, or no obstacle is indicated at all.

This means that the original obstacle is in the blind spot of the sensors (construction-related characteristic), and it is possible to hit it.

12 Troubleshooting

The device indicates no function.

The voltage supply cable (black/blue and brown wires) is not connected or is incorrectly connected.

▶Check the connections.

The plugs for the sensors are not connected or are not properly plugged into the control electronics.

▶Check the plugs, and make sure they lock into place.

A long tone sounds (approx. 3 seconds) after switching on the ignition

One or more sensors are defective or no longer connected to the control electronics. The loudspeaker indicates the faulty sensor by the number of beeps after the long beep: for example three beeps for sensor 3.

▶Check the plugs and make sure they lock into place.
▶Replace the defective sensor(s).

NOTICE!

The system no longer works reliably if one or more sensors are faulty.

Device indicates obstacles incorrectly.

False alarms may have the following causes:

• For example dirt or frost on the sensors
  ▶Clean the sensors.
  • The sensors were incorrectly installed.
  ▶ Adjust the direction or height of the sensors (fig. 3).
  • The sensors have contact with the chassis.
  ▶Disconnect the sensors from the chassis.

Objects on the vehicle (e. g. spare wheel) lead to false alarms.

▶ Set the system so that fixed objects are no longer displayed (see chapter "Setting the system" on page 9).
