1. Wi chrono User Manual Last Update January 30 2012 Version 2 0 Page 1 Thank you for choosing Agility In Motion Wi Chrono The Wi Chrono wireless timer system was designed for ease of use and portability while preserving a rich feature set The system consists of 1 1 or more Station Set Each set is composed by one Beam Emitter and one Receiver The Emitter is responsible for sending a beam of infrared waves to the receiver The infrared light is invisible to human eye and harmless to animals and persons it uses the same technology as TV remote controls The Receiver is equipped with a beam waves sensor and detects any interruption in the path of light sending a wireless notification to the Console unit This notification will be interpreted as an indication that an object has crossed the infrared link between the Emitter and the Receiver No configuration of any kind is required for operation of the beam emitter and receiver set A Console unit that is responsible for displaying the elapsed time and interpreting the signals sent by the Station Sets The Console unit provides partial times and allows to interchange between partial times and accumulated times The only configuration input to the Console unit is a knob to adjust how many partial times you want to account for Packing list Version 2 0 Page 2 Console unit Fig 1 Console Unit Station Set The set is compos2. display is too dark and makes it difficult to read the numbers Possible reasons and suggested actions e The system has been adapted to be used with rechargeable batteries Replace the alkaline batteries with rechargeable batteries Symptom The Console Unit does not recognize a broken beam event Possible reasons and suggested actions e See The Receiver is unable to see the beam from the Beam Emitter Version 2 0 Page 17 10 Frequently Asked Questions Question I want to add another Receiver and Beam Emitter set is it possible Do I need to give you a code or anything Answer Yes you can add up to 8 sets All the Beam Emitters are the same amongst them and also the Receivers so there is no need to inform us of any code or frequency since they are all exactly the same Question My friends have a Agility In Motion Wi Chrono also can I use their Receiver and Beam Emitters Answer Yes you can The Console Unit is not restricted to a set of components they are all the same and can be shared Question I have 2 sets of Agility In Motion Wi Chrono but noticed that when I used them together they get activated at the same time Answer Yes that is correct If you plan to use both systems at the same time but want to preserve their independence we can reprogram them for you Please contact us Question What is the accu
3. Beam Emitter 5 1 LEDs and IR Infrared transmitter The clear light on the left side of the box is the infrared LED emitter The green LED on the front of the box is the On Off indicator The red LED is the Low Battery indicator The infrared LED emitter is a very low power device and completely harmless for dogs and humans It uses the same technology as a regular TV remote control Turn the box On Off by applying slight pressure on the Power switch Version 2 0 Page 8 6 Receiver 6 1 LEDs and IR reception sensor The orifice on the right side of the box allows the reception of the infrared light emitted by the beamer while insulating the sensor from direct sunlight exposure The green LED on the front of the box is the On Off indicator The red LED is the Low Battery indicator The LED closest to the orifice the yellow LED in this picture is the Alignment indicator This LED turns on and stays on as long as the infrared signal sent from the Beam Emitter is received Fig 11 Turn the box On Off by applying slight pressure on the Power switch Version 2 0 Page 9 6 2 LED status description When the Power Switch in the Off position you would observe that no LEDs are lit Fig 12 Power switch and On Off LED Indicator When you turn the device on and provided that the batteries are installed and charged you will observe one of the following Fig 13 a Unit is ON Aen LED is OF
