What is GPS? |
 |
Global Positioning System (GPS) is a worldwide radio navigation system that uses 24 satellites that orbit the earth. GPS receivers, like Road Angel, use these satellite signals to calculate it's position to a couple of metres .

My Road Angel keeps displaying the message ‘Please register’ every time it is switched on. |

In order to clear this message you need to complete an update. For more information on how to update Road Angel click here.

|
How much warning does Road Angel provide? |
|
Road Angel has three proximity options for Fixed cameras; these are 250m, 500m or 1000m. There is an additional setting called SDS or Speed Distance Setting. If you activate this setting your proximity warning is doubled if your speed is over 50 MPH. You cannot increase the sensitivity of the laser detector.

How often should I update my Road Angel to receive the new locations? |
|
As a guide we recommend updating your Road Angel approximately every two weeks.

|
ROAD ANGEL COMPACT loses the satellite signal |
|
This may happen temporarily owing to tunnels, tall buildings, bridges or dense foliage. When you are clear of the obstruction, ROAD ANGEL COMPACT should re-acquire satellite signals in a few seconds.
Have you moved the unit within the vehicle? Reposition ROAD ANGEL COMPACT to its original position.
You may be experiencing poor GPS coverage – very occasionally one or more satellites are out of sequence and the signal temporarily drops out. It should be restored within minutes. |

My Road Angel does not display my speed, it just displays 'Searching for satellites' |
|
Road Angel has an internal GPS receiver that needs to have a view of the sky in order to obtain the satellite signals required to calculate it’s position. Road Angel needs to be positioned on the dashboard of the vehicle or by using the windscreen bracket in order to do this. For discreet mounting, an antenna can be used. Click here for more information. Some vehicles, for example Renault, Citroen, Peugeot some BMWs and Mercedes have what is known as an Athermic, comfort or UV windscreen. This interferes with the satellite signal being received by Road Angel which results in either no speed being displayed, intermittent or erratic speeds. An antenna will be required, click here for more information.

The Road Angel has an internal battery that holds the Road Angel's almanac data. The almanac data tells the GPS receiver where each GPS satellite should be at any time throughout the day. Each satellite transmits almanac data showing the orbital information for that satellite and for every other satellite in the system. Basically the Road Angel 'learns' where the satellites should be and this helps the speed of the acquisition. If the battery runs down it will lose the almanac data and the acquisition time will be increased. |

No audible signal |
|
On powering the unit, irrespective of the volume level, the unit will sound. If you can hear this then the volume has been adjusted to minimum.
- Press MENU to move to Alert screen.
- Press DELETE to open the Camera alert volume setting.
- Press DELETE to edit the value.
- Press DELETE repeatedly until the display shows the required value.
- Press STORE to save the setting.

The speed display on Road Angel differs slightly to the speedometer in my car. |
|
At a constant speed the Road Angel has a more accurate speedometer reading than that of the car. This is because the speedometer readout is governed by the rolling circumference of the tyre in contact with the road surface. Different tyre pressures, sizes and tread ware can all make a difference to the speedometer reading. For this reason every manufacturer has to calibrate the speedometer to ensure that at no point can the vehicle be traveling faster than is indicated. The Road Angel speed lags because it checks it's position once a second, there will always be a delay under acceleration and deceleration.

I have driven past a fixed safety camera and did not receive a warning. |
|
There are a number of reasons why this can occur.
- The camera has been logged and added to the central database since you last update was completed. For assistance updating Road Angel click here.
- The camera was on the opposite side of the road. Some Safety Camera Partnerships and Councils paint white lines on the opposite side of the road to the camera to give an impression that it can enforce in either direction, when in fact this is not the case.
ROAD ANGEL COMPACT has a directional feature that allows it to ignore cameras that are enforcing the speed limit in the opposite direction.
- It was not a speed camera. There are lots of street furniture that can be mistaken for a speed camera. For example; Red Light enforcement cameras, Automatic Number Plate Recognition (ANPR) systems and traffic flow measurement systems. For more information on the types of safety cameras click here.

I have driven past a Safety Camera van and did not receive an alert |

To detect Safety Camera vans and hand held roadside laser speed
measurement guns, Road Angel Compact requires the additional clip-on
Laser Alert module. To order one click here. For more information on laser detection click here.

I am not getting sufficient warning as I approach fixed cameras |
|
Increase the Alert distance setting:
- Press MENU twice to move to the Distances screen.
- Press DELETE to enter the menu.
- Press DELETE to edit the Alert distance
- Press DELETE repeatedly until the unit shows the required value.
- Press STORE to save the setting.

Sometimes when I am driving I get a warning for a camera that is not there? |
|
Has the unit been updated recently? The camera may have been removed from the database.
ROAD ANGEL COMPACT may be warning you about a camera on a parallel road very close to the road you are travelling on. If this is the case, the proximity bars may switch off before they go all the way to maximum. This problem is more likely to occur if your ROAD ANGEL COMPACT is set to a long alert distance setting; to reduce this:
- Press MENU twice to move to the Distances screen.
- Press DELETE to enter the menu.
- Press DELETE to edit the Alert distance
- Press DELETE repeatedly until the display shows the required value.
- Press STORE to save the setting.

I was flashed by a GATSO camera that was on the opposite side of the road. |
|
A GATSO camera can only enforce the speed of vehicles traveling away from it. When there is no film in a GATSO, the trigger threshold for a flash is often lowered, and the camera may be set to also flash approaching vehicles. The photograph cannot be used to enforcement or prosecution.

I am getting an Alert to fixed cameras that are not there. |
|
It is possible that the cameras have been removed from the central database since your last update. For assistance updating Road Angel click here. Road Angel is directional, in that it only alerts you to cameras that can enforce the speed in the direction you are traveling. If there is a camera on a road nearby that enforces in a similar direction to the one you are traveling you may start to get an alert. In most cases the alert will drop out before it reaches the full 5 bar warning. The bigger distance setting you have Road Angel set too, the more likely you are to receive an alert to cameras on a different road.

Can I move Road Angel from vehicle to vehicle? |
|
Yes, Road Angel has been designed to be easily transferable between vehicles. If you require additional cables, brackets or dashpads you can purchase these separately. Click here to visit our online shop.

|
My road Angel Compact keeps displaying the message “Data out of Date” every time it is switched on? |
|
The reason for this is the location data inside the unit hasn't been updated in the last 28 days. Carry out an update as normal and this will clear the message.
