Manual zz. The 'XT has more memories up to 25, channels! Some of these features have never been available on any scanner before. In addition to all this the latest firmware version even allows individual Unit ID's for identifying specific radios in trunked systems.

Coded squelch techniques involve the transmission of a special 'code' signal along with the audio of a radio transmission. A receiver with coded squelch only activates when the received signal has the correct 'code'. This lets many users share a single frequency, and decreases interference caused by distant transmitters on the same channel. In all major metropolitan areas of the United States, every available radio channel is assigned to more than one user.
Public safety radio systems on the same frequency are usually set up at a distance of 40 miles apart, or more. This means that you may hear transmissions from a distant system when your local system is not transmitting. By programming the CTCSS tone for a local channel the scanner will not stop on transmissions from the distant system. Trunkscanning is basically scanning IDs that are programmed into ID locations same concept as frequencies into channels.
You can then trunkscan just the programmed IDs. Trunktracking is searching for all IDs in a system same concept as searching for frequencies in a band. Creating Groups Once you have your Systems built, systems options configured, trunking system Sites Created , and Site Options configured, you can create your groups. Continue at ' Edit Name ' below. To Edit Group Options press Menu.

Even if you don't use the scanner to scan, you can enhance you GPS unit with information the scanner provides. If you are traveling at a speed greater than that specified, in the direction specified, and if you are within range of the set location, the scanner sounds an alert at.
These range distances are also automatic and fixed. You can also temporarily lockout cancel any combination of these alerts. Make sure that the cable terminates in a female, 9-pin serial connector and you select the correct baud rate bps for the rear serial port. The scanner will display ' Searching for Satellite ' in GPS Display Mode until it receives the signal from the satellite if you have your connections and baud rate set correctly. The first time the scanner starts receiving a signal from the GPS, it briefly displays ' GPS Connected ' and temporary locks and unlocks all systems and sites that are 'enabled for scan', unlocked, and whose quick key is enabled according to your current location.
If you have a lot of data programmed, it might take the scanner a couple of minutes to complete the process. The scanner opens a dialog ' Storing Location ' to store your current location or ' Location Exists ', Accept? Press Menu twice to exit. To Program a New Location press Menu. To Edit an Existing Location press Menu. The second condition is speed.
It meets this condition when the current speed exceeds the speed that is set in Set Speed Limit. When a second alert with a higher priority occurs during the current alert, the current alert is canceled and the scanner alerts for the higher priority alert.
In this mode, you can see the current location information as well as information about your position relative to selected POI's. The right side of the 1st line displays the present time. The left side of the 2nd line displays the current speed. The right side of the 2nd line displays the elevation of the current location.
The 1st line displays the latitude of the current location. The 2nd line displays the longitude of the current location. The left side of the 1st line displays the current direction of travel. The 2nd line displays the distance to the selected POI.
The 3rd line displays the name of the selected POI. To Select a PIO turn the scroll control. Note: If no programmed location is displayed ' OFF ' in the display , you will only be able to toggle 'Data Display' and the current 'Location Display'.
The scanner automatically unlocks the locked out location when it moves 2? If you lose the satellite signal, you will see ' Searching for Satellite ' until the GPS unit reacquires a signal.
It applies the location-based rules to all systems at one time. The most recently stored location is displayed. Use the scroll control to display the next screen for review. Note: the scanner will mute in this mode. Important: while you are in Review Location Mode and press and hold GPS for 2 seconds, the data of the new point will overwrite the currently displayed data.
Range - Indicates the programmed distance to your POI. Head - Indicates the selected heading to the designated Dangerous Crossing from any direction. Head - Indicates the selected heading to the designated Dangerous Road from a set direction.
LS - Indicates the maximum Speed Limit you set. Priority Scan When the scanner is scanning a conventional system, it interrupts scanning every 2 seconds to check priority channels for activity. The more channels you have set to priority, the longer the interruption will be.
The quick keys for the system s and group s containing the priority channel s have to be enabled and unlocked or the scanner will display ' Priority Scan No Channel '. Priority Plus Scan The scanner only scans priority channels in unlocked conventional systems with system and group quick keys enabled.
Priority for priority channels in the same channel group follows the order in which the channels were created. To Use Priority Scan you must first set your priority channels. You can also toggle these modes by pressing PRI in scan mode. Off - scans normally with no priority. On - the scanner interrupts every 2 seconds and checks conventional priority channels. PRI appears in the display when you select this mode.
Plus On - the scanner only scans the priority channels. PRI flashes in the display when you select this mode. To Use a Startup Key: 1. Turn the scanner off. Continue holding the number key until the scanner display shows the number of the startup key configuration.
When you use startup configuration, the scanner checks all systems, sites, and search ranges and: 1. All systems, sites, or search ranges that do not have a startup key assigned will be scanned the way they were when you last turned off the scanner. All systems, sites, or search ranges that have a startup key assigned to the one you pressed will be unlocked. All systems, sites, or search ranges that have a different startup key assigned will be locked out. The scanner will remember the last startup configuration you used when you power up the scanner using just the power key.
Caution: If you press the wrong key when you press the power key to set your startup configuration, and that wrong key doesn't have any systems assigned to that key, you will startup your scanner with all systems locked out. You can't start Key-Safe mode and Startup Configuration at the same time i. Also, you can't cancel Startup Configuration, i. Conventional channels within the groups are scanned in order of creation. IDs are not really scanned. The scanner checks for any activity in the trunking system and if any ID becomes active, the scanner will display it in 'ID Search' mode.
Then the scanner scans the system called 'Close Call'. This system is created if you do a Close Call 'Auto Store'. If the 'Close Call' system has no frequencies, the scanner does not scan the system. Then the scanner scans the 'Close Call Hits' system if you have unlocked it; locked out by default.
This is a system that automatically stores the frequencies found by Close Call. If the 'Close Call Hits' system has no frequencies, the scanner does not scan the system. Then the scanner starts all over. The scanner scans a system for the duration you set using the 'system hold time' option. For trunked systems, the scanner moves to the next system after the hold time expires, the current transmission ends, and the channel delay expires.
Conventional systems operate similarly, but all unlocked channels are scanned at least one time regardless of the hold time setting.
Notes: If no systems are programmed, or all systems or groups in a system are locked out or turned off, ' Nothing to Scan ' appears. If you turn off all groups in a system you will not be able to turn any back on and also see ' Nothing to Scan '. This is a bug that frustrates everybody. Scroll to the system then press the number of the group quick key s you want to enable. To change the scan or search direction turn the scroll control backward or forward.
Press Hold to resume. No first then enter the 2 digits. To hold on any specific frequency Hold on any channel in a conventional system. Enter the new frequency and press Hold. To hold on a specific ID in the current site Hold on the site.
