Limitations on Temperature Readings
Since the temperature sensor for your SporTrak Color is inside the receiver, it is trying to
read the temperature of the receiver and not your ambient temperature. There has been
compensation made to the temperature readings in order to accurately represent the
ambient temperature. Some of those compensations come from the values that you may
have entered if you calibrated the temperature. Even with all of the compensation, the
temperature displayed will still be adversely affected if the receiver is in severe temperature
environments. For example, if you place your SporTrak Color on the dashboard of your
car or anywhere where the sun is repeatedly beating on it, the internal temperature of the
receiver will rise above a point where the temperature compensation values are just not
enough. As with any electronic device, it is not good practice to place it in those types of
extreme temperatures.
