Beyond the Basics

Q:Error appears on the display. What does it mean?

A:If you were trying to enter a frequency, you might have made a programming error. Re-enter the frequency correctly, including the decimal point.

Q:My scanner does not track EDACS systems properly. What’s wrong?

A:The logical channel numbers (frequencies) for the system might not be programmed in the correct order, or all the frequencies might not be programmed. Check the frequencies and reprogram them.

Q:I do not hear all the replies to conversations. What’s wrong?

A:Change to a Type 1 scanner setup. See “Fleet Map Programming” for more information. Try another preset ﬂeet map or program your own ﬂeet map. Check to see that all the system’s frequencies have been entered.

Q:The scanner does not acquire the data channel. What’s wrong?

A:Adjust the squelch for trunking mode. See “Setting the Squelch”. Also, the frequency used for the data channel might not have been programmed into the scanner.
