Page 6: Welcome To Decatur Electronics
We urge you to study this manual before using the GHD or SCOUT so you can maximize the benefits of this sophisticated radar device. This Decatur radar product might appear similar to earlier models, but its digital signal processor (DSP) gives the device advanced capabilities. -
Page 7: About This Manual
All service needs should be referred back to the manufacturer. Do not over voltage the radar - it can damage the unit! The GHD and the SCOUT are designed to operate off of conventional +12 VDC (10.8 to 16.5 VDC) from their power cables. In addition the SCOUT is also designed to operate at 7.2VDC from the internal batteries. -

& SCOUT USER’S MANUAL 4.2 Display Number Segments The three large digits (888) on the left display the vehicle speed. The three small digits on the right display either the locked speed or Faster target speeds depending on the setting you have selected (see Figure 4.2). - Page 16 & SCOUT USER’S MANUAL LOCK The LOCK icon indicates the speed previously displayed on the left window is now locked and will appear in the right window. FAST FAST shows that the radar is in Faster mode. When the device is not in Faster mode, it is in Strongest Signal mode, which is the default mode.

& SCOUT USER’S MANUAL Mini-Test (tSt) The tSt option sets the system to automatically perform a “mini” self test every 10 minutes. Beep (bEP) The bEP option sets the system to give an audible “beep” to verify every time a key is pressed. bEP ON is the default setting. Power Down (Prd) The Prd option is designed to maximize the amount of time the radar can operate before the batteries need to be recharged. -

& SCOUT USER’S MANUAL The vehicle going 70 mph is the strongest target going faster than the strongest. 5.5 Faster-Toggle Mode In Faster-Toggle mode, you can toggle between the Faster and Strongest Signal targets by pressing the FAST button (the FAST icon illuminates.) To switch from Strongest Signal target to Faster target, press and release the FAST button. -
Page 24: Serial Output Mode
Figure 5.6 6. Serial Output Mode The GHD and the SCOUT have an RS232 communications port on the bottom of the handle. Using a custom RS232 communications cable, you can connect the SCOUT and transmit data to display signs, in-car video, and PCs for recording and analyzing speed data. -
Page 25: Performance Tips
& SCOUT USER’S MANUAL 7. Performance Tips Understanding potential radar interference and what to do when it occurs can greatly increase the radar’s performance. 7.1 How Radar Works Determining a vehicle’s speed begins with the radar gun transmitting a beam of microwave energy (radio waves) at an approaching or departing target vehicle. -
Page 26: Angular Interference (Cosine Error Effect)
& SCOUT USER’S MANUAL 7.3 Angular Interference (Cosine Error Effect) The cosine effect causes the system to display a speed which is lower than the actual vehicle speed. This condition occurs when the target vehicle’s path is not parallel to the antenna, including conditions such as the vehicle traveling on a curve or hill. -
Page 27: Fan Interference
& SCOUT USER’S MANUAL The following table shows the effect that an increasing angle has on a displayed speed. Figure 7.3b Actual and displayed speeds at antenna-to-target angles Small angles (less than 10°) have little effect on accuracy. As the angle increases, the displayed speed decreases. -
Page 28: Feedback Interference
At that time, any locked speeds will display again. 7.9 Scanning The GHD and SCOUT are designed to be used while attached to a solid mount or hand-held in a steady position. Moving or “scanning” the antenna past stationary objects can cause the system to detect motion. -
Page 29: Vehicle Ignition Interference
& SCOUT USER’S MANUAL 7.10 Vehicle Ignition Interference The GHD and SCOUT have been designed to operate from the vehicle’s cigarette lighter receptacle (or from the 6 internal AA Nickel-Metal-Hydride batteries located in the base of the handle in the case of the SCOUT). When connected to the cigarette lighter receptacle it should be noted that some vehicles exhibit excessive alternator noise at the lighter receptacle. -

Place the vibrating tuning fork about 3 inches in front of the antenna. If the device does not display the expected speed, contact Decatur Electronics Customer Service at +358 207 528 508 to arrange for service. Only tap the tuning fork against hard plastic, wood, and materials that are softer than metal. -
