After connecting the antennas, the decoder can be powered on by briefly pressing the ON-button. The booting process will begin. In order to turn off the decoder, push and hold the OFF-button for approximately 8 seconds.

After booting, the decoder will be in Test Mode. As long as transponders are within range of the antenna, you should hear a constant beeping. This allows you to check if the antenna is connected properly and if it detects everywhere. The detections in Test Mode will not be saved and cannot be read out. 

Next, you should set your decoder's internal clock to the current time of day. This can be done by opening the "Menu > Time" Settings. By selecting Start GPS Time your decoder will now search for available Satellites and set an accurate time of day. If this fails (normally only if you are indoors) the decoder may offer an estimated time, which you can accept by pressing OK, or you can also set a time of day manually by choosing Set Running Time. You should also check the GPS time zone of your decoder which is found through the same menu. 

Once you have tested your system and you are confident that it is reading transponders well across the whole antenna field then you should press START to set the decoder to Timing Mode, which will start recording passing data. We recommend switching to Timing Mode as soon as your system is setup, then you are done with the hardware side of things and can focus on the timing and scoring. 

Passive System only: You will notice that the transponders can be detected at a large distance from the antenna. Similarly, the decoder may beep during the race before the athlete has passed the antenna. However, this does not imply imprecise time keeping: after the first detection of the chip (beep) it will be read many times and in the end the time with the highest signal strength (right above the antenna) will be saved.
