I have a new Cobra which has not been in the water yet. I found in the manual, and on the computer menu tree, where to turn the backlight on and off and the timer. What I cannot find out is what makes it come on other than a refference to the fact that if it is turned off it will not come on in the event of an alarm.
How do you turn it on to take a reading? Can anyone help?
