I have a satzen 500 receiver and am having trouble inputing my server port setting due to fact number starts with 0....when entering number and pushing ok it will show 0xxxx but when out of screen than back in screen to see info it drops the 0 and shows the last 4 numbers only, how can I get receiver to keep that 0 and show the 5 digit number instead of reverting back to a 4 digit number via dropping the needed 1st digit number 0 ? Anyone have this trouble ?, and if so could you help me out? Thank You
