OPEN AND CLOSED MODES

When set to the open mode, the scanner stops on any ID code and only uses the ID list to look up ID text tags.

When set to the closed mode, the scanner stops only on signals that have an ID code which is found in the ID list for the bank.

Note: When you select a channel manually, any transmission opens squelch, regardless of the current mode.

The open or closed mode is set in each channel storage bank. öý(open)ýor V (closed) appears under the channel storage bank's number while scanning. Or, the status dis- play shows the ö or V at the top line while the scanner is in manual mode or receiving a signal during scanning.

When no ID code is programmed into the scanner, it receives the signal in MOT or ED mode. In open mode the scanner stops on any transmission. If the ID is stored, the text tag appears in the display. Otherwise, the talk group ID appears in the display. In closed mode the scanner only stops on a

transmission if the ID is stored. This is very useful when you want to narrow the scan in areas where numerous entities utilize the same trunking system. For example, if the police department, sheriff’s department, fire department and EMS all use the same sys- tem in your area you can program the identi- cal trunking frequencies on 4 separate banks. Then by manually storing their re- spective group IDs into corresponding banks (i.e. police IDs in bank 1, sheriff’s IDs in bank 2, fire rescue IDs on bank 3, and EMS IDs on bank 4) and setting the banks to the closed mode, you can choose which service you want to listen to. (See “Turning Channel- Storage Banks Off and On” on Page 25.)

ˆA General Guide to Frequencies

Reception of the frequencies covered by your scanner is mainly "line-of-sight." That means you usually cannot hear stations that are beyond the horizon.
