In cold temperatures (10 degrees F or below), the Liquid Crystal Display (LCD) on your Dogtra 3502 NCP transmitter may be dim or slow to respond. Wait until the display becomes visible before selecting any training level. Even though the LCD screen might be dim or slow to respond, when you push the Nick or Constant button, the transmitter Dogtra 3502NCP will still function properly. In the occurrence of extremely cold weather, the LCD screen might take a moment to respond causing the Intensity level to freeze at that current level. In this situation, if you turn the Rheostat Intensity Dial, and the intensity level on the screen does not increase, yet you emit an electrical stimulation, the level will be in agreement with the new changed intensity level.In this situation, it is ideal to either wait until your transmitter Dogtra 3502NCP is back to working order before emitting a correction.
