61Trunking Operation Turning an ID Sub-Bank On or Off Follow these steps to turn the ID sub-bank on or off dur- ing the program mode: 1. Press TRUNK repeatedly to select the desired sub- bank. 2. Press FUNC then 1 to turn the sub-bank on if it is off or off if it is on. Follow these steps to turn the ID sub-bank on or off dur- ing the scan mode: 1. Press FUNC while the scanner is stopped on a voice channel transmission. 2. Press TRUNK. The display indicates which sub-bank is turned on or off, and the active sub-bank number flashes. 3. Press FUNC and the number of the sub-bank you desire to turn on or off. For example to turn sub- bank 4 on or off, press FUNC then 4. Locking Out Talk Group IDs Note: You can only lock out talk group IDs when the scanner is in the closed mode (see “Open and Closed Modes” on Page 63). 1. Press PGM. 2. Press TRUNK. 3. Press FUNC, 8 88 8 or 9 99 9to move to the desired bank. 4. Press 8 88 8 or 9 99 9 to select the ID memory. 5. Press L/OUT to lock out the ID. Bý BýBý Býappears. 6. To remove the lockout from a trunking ID, manually select the ID memory, and press L/OUT until ( (( (ý ýý ýdisap- pears. You can confirm the ID code while the scanner shows the text when the received signal is a voice channel.
62 Trunking Operation 1. Press TEXT while the scanner is receiving the voice channel and indicating the text name. The ID code appears as )+0è444444 )+0è444444)+0è444444 )+0è444444 or ! è4444 ! è4444! è4444 ! è4444. 2. Press TEXT again to cancel. Delay Function in ID Indication Mode You can set the ID delay function separate from the channel delay. 1. Press FUNC then ./DELAY while you are program- ming the trunked ID. 1J
63Trunking Operation Clearing All Talk Group IDs in One Bank You can clear all talk group IDs within a bank. This lets you quickly delete all talk group IDs from a bank if you want to use the bank to store different data (such as a new set of talk group IDs). 1. Press PGM. 2. Press TRUNK to enter a talk group ID memory mode. 3. Select a talk group ID bank using FUNC, 8 88 8 or 9 99 9. 4. Press FUNC then 6. áFE=@IDý C@JKý :C
64 A General Guide to Frequencies 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 system in your area you can program the identical trunk- ing frequencies on 4 separate banks. Then by manually storing their respective 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 Chan- nel-Storage Banks Off and On” on Page 41.) Changing the Open/Closed Mode 1. Press MANUAL. 2. Press FUNC then 8 88 8 or 9 99 9 to select the channel storage bank. 3. Press FUNC then 5. â8EBý +,!* â8EBý +,!*â8EBý +,!* â8EBý +,!*ô ôô ô or â8EBý á(+/! â8EBý á(+/! â8EBý á(+/! â8EBý á(+/! ô ôô ô appears. After that message disappears, the tenth digit on the top line of the display changes from ö öö ö to V VV V or vice versa. 4. Repeat Steps 2 and 3 for each bank. 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.
65A General Guide to Frequencies US Weather Frequencies in MHz 162.400 162.425 162.450 162.475 162.500 162.525 162.550 Ham Radio Frequencies Ham radio operators often transmit emergency informa- tion when other means of communication break down. The chart below shows the frequencies the scanner re- ceives that ham radio operators normally use: Birdie Frequencies Every scanner has birdie frequencies. Birdies are sig- nals created inside the scanners receiver. These operat- ing frequencies might interfere with transmissions on the same frequencies. If you program one of these frequen- cies, you hear only noise on that frequency. If the inter- ference is not severe, you might be able to turn SQUELCH clockwise to omit the birdie. This scanners birdie frequencies (in MHz) are: Wavelength Frequencies (MHz) 10-Meter 28.000–29.700 6-Meter 50.000–54.000 2-Meter 144.000–148.000 70-cm 420.000–450.000 33-cm 902.000–928.000 25-cm 1240.000–1300.000 VHF Low Band (MHz) 25.5000 38.2500 41.8900 51.000
66 A General Guide to Frequencies To find the birdies in your scanner, begin by disconnect- ing the antenna and moving it away from the scanner. Make sure that no other nearby radio or TV sets are turned on near the scanner. Use the search function and scan every frequency range from its lowest frequency to the highest. Occasionally, the searching will stop as if it had found a signal, often without any sound. This is a birdie. Make a list of all the birdies in your scanner for fu- ture reference.

68 A General Guide to Frequencies Primary Usage As a general rule, most of the radio activity is concentrat- ed on the following frequencies: VHF Band UHF Band Note: Remote control stations and mobile units operate at 5 MHz higher than their associated base stations and relay repeater units. BAND ALLOCATION To help decide which frequency ranges to scan, use the following listing of the typical services that use the fre- quencies your scanner receives. These frequencies are subject to change, and might vary from area to area.
