61 Programming the Base and Offset Frequencies To properly track Motorola VHF and UHF trunked sys- tems, you must program the applicable base and offset frequencies for each system. A list of these frequencies can be found at www.trunk- scanner.com and other similar frequency resources. 1. Set the scanner for conventional scanning. Press PROG then TRUNK. 2. Press the number key of the bank where you want to store the base frequency. 3. Repeatedly press V or W to select E2-VHi or E2-UHF, then press E. A previously programmed trunked frequency appears 4. Press D ATA ( A LT ). The preset base frequency appears. 5. Enter a desired frequency. 6. Press DATA (ALT). The preset offset frequency appears. 7. Enter the frequency using the number keys accord- ing to the following guide: • For Motorola Type II VHF, (E2-VHF Hi band) use 5kHz steps between 5 kHz – 100 kHz. • For Motorola Type II UHF, (E2-UHF band) use 12.5kHz steps between 12.5 kHz – 100 kHz. Programming a Hybrid System A hybrid system is simply a Type I system with some of its blocks designated as Type II blocks. To program a hybrid system, follow the steps listed in “Programming a Fleet Map” on Page 60. However, if you want a block to be Type II, instead of pressing V or W to select the size block (Step 7), enter size code S-0 instead. 20-524.fm Page 61 Tuesday, August 31, 1999 3:55 PM
62 Turning On/Off the Motorola Disconnect Tone Detect Function While trunking a Motorola system, your scanner auto- matically tunes to the data channel when it detects a disconnect tone (a code that tells the trunking system that the transmitter has finished sending) on the voice channel. You can manually turn off this function so the scanner does not tune to the data channel under those condi- tions. You might use this feature to listen to weak trans- missions when conversations are generally disconnected. To turn the disconnect tone detect function on or off, set the scanner to trunk track then press SVC. The scanner beeps and DATA flashes for about 5 seconds. Notes: • To set the scanner so it remains on the voice chan- nel (even when a disconnect tone is transmitted or there is no signal at all) set SQUELCH so you hear a hissing. • You cannot use the disconnect tone detect function if you are programming a trunking frequency or a fleet map. To set the scanner to automatically tune to the data channel once again when it detects a disconnect tone, press SVC (E) . 20-524.fm Page 62 Tuesday, August 31, 1999 3:55 PM
63 A GENERAL GUIDE TO SCANNING Your scanner’s reception is mainly “line-of-sight.” You usually cannot hear stations that are beyond the hori- zon. GUIDE TO FREQUENCIES National Weather Frequencies Birdie Frequencies Every scanner has birdie frequencies. Birdies are sig- nals created by the scanner’s internal circuits. These stray frequencies might interfere with broadcasts on the same or similar frequencies. If you program one of these frequencies, you hear only noise on that frequen- cy. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. This scanner’s known birdie frequencies (in MHz) are: 162.400 162.475 162.525 162.425 162.500 162.550 162.450 41.6000 145.6000 165.3000 171.2500 407.7625 407.8125 413.1750 413.2250 415.0000 435.9250 455.7375 465.6500 485.4625 489.2500 823.8000 899.2375 906.4125 906.5875 926.7000 1290.7000 20-524.fm Page 63 Tuesday, August 31, 1999 3:55 PM

GTR FREQUENCY CONVERSION The tuning location of a station can be expressed in frequency (kHz or MHz) or in wavelength (meters). The following information can help you make the necessary conversions. 1 MHz (million) = 1,000 kHz (thousand) To convert MHz to kHz, multiply the number of mega- hertz by 1,000: 9.62 (MHz) ´ 1000 = 9620 kHz To convert from kHz to MHz, divide the number of kilo- hertz by 1,000: 2780 (kHz) ¸ 1000 = 2.780 MHz To convert MHz to meters, divide 300 by the number of megahertz: 300 ¸ 7.1 MHz = 42.25 meters 20-524.fm Page 68 Tuesday, August 31, 1999 3:55 PM
69 TROUBLESHOOTING If your PRO-94 is not working as it should, these sug- gestions might help you eliminate the problem. If the scanner still does not operate properly, take it to your local RadioShack store for assistance. Problem Possible Cause Remedy Scanner is on but will not scan.SQUELCH is not adjusted cor- rectly.Turn SQUELCH clockwise. Only one channel or no channels are stored.Store frequencies into more than one channel. Scanner is totally inoperative.No power. Check the batter- ies or make sure the AC adapter or DC adapter is connected prop- erly. Recharge the rechargeable bat- teries or replace the non-recharge- able batteries. The AC adapter or DC adapter is not connected.Be sure the adapter’s barrel plug is fully plugged into the POWER jack. The scanner’s display dims or the scanner sounds a tone every 15 –30 sec- onds.Batteries are not correctly installed.Make sure the batteries are installed properly. The batteries are weak.Recharge the rechargeable bat- teries or replace the non-recharge- able batteries. The keypad does not work.The keylock func- tion is activated.To turn off the keylock, press KEYLOCK until K/L disappears. 20-524.fm Page 69 Tuesday, August 31, 1999 3:55 PM
70 BATT. Lo flashes.The batteries are weak.Recharge the rechargeable bat- teries or replace the non-recharge- able batteries. Poor or no recep- tion.Batteries are weak or com- pletely dis- charged.Check the batter- ies or make sure the AC adapter or DC adapter is connected prop- erly. An antenna is not connected or is connected incor- rectly.Make sure an antenna is con- nected to the scanner. Error appears.Programming error.Re-enter the fre- quency correctly, including the deci- mal point. The scanner locks on frequen- cies that have an unclear transmis- sion.Stored frequen- cies are the same as “birdie” fre- quencies.Avoid storing fre- quencies listed under “Birdie Fre- quencies” on Page 63, or only listen to them manually. The scanner does not track a trunked system.The transmis- sion might not use a system that can be tracked by your scanner.Scan another transmission. The data fre- quency is miss- ing.Find the data fre- quency (see “Storing Trunked Frequencies” on Page 43). The system you are trying to track is a Type I sys- tem, and the scanner is set to scan Type II sys- tems.Set the scanner to receive Type I trunked frequen- cies. See “Scan- ning Type I and Hybrid Trunked Systems” on Page 55. Problem Possible Cause Remedy 20-524.fm Page 70 Tuesday, August 31, 1999 3:55 PM
