Just took delivery of a SDS200 from bearcat warehouse. This thing is awesome and its doing an excellent job at picking up everything i want to hear. One question i had though is, does it hurt to leave the display on all the time? By default it seemed to go out after a minute or 2 of not pushing any buttons or no radio transmissions. I changed it to infinite but not sure if it hurts to leave it lit up all the time or should i turn it off when im not near the scanner. I leave it on pretty much 24/7 but only am sitting near it for an hour or 2 a day. Do most people leave it lit up or turn the display off?
