I just finished installing a "blinking" module on my Telrad. It is really slick!! It allows you to set the target symbol from full on to slow blink, to everything in between. A new dial switch controls the on-off, and the original switch just controls brightness. I think that this will stop the problem I have been having with the telrad "going on" while in my case. Sucks to find the unit on and the batteries dead!!
