NEED SOME HELP.... I have recently programmed my SM-4150EX with all of the channels that I need. I write the freq's to the radio, turn it off and bam ER. 03. According to the manual it tells me that something is not compatible.
What do I do now?
Are there any Diagnostics programs that I can use to test the radio?
ER-03 means that the synthesizer is out of lock due to a frequency entered that is out of range of the bandsplit of the radio or is out of range of the current synthesizer tuning.
If you entered valid frequencies within the bandsplit of the radio, then it needs realignment. That radio is only good for an 8MHz frequency spread within the nominal bandwidth without degredation although the synthesizer should stay lock over a 10 MHz range.
What frequencies were in the radio before you reprogrammed it and what frequencies are you attempting to enter?
