31 LISTENING TO THE MONITOR MEMORIES To listen to the frequency stored in any one of the ten monitor memories, press MAN, MON/CLR (•), then the number of the desired monitor memory (0– 9), or re- peatedly press MON/CLR (•) to step through the monitor memories. Note: To listen to the monitor memories, the priority channel feature must be turned off (see “Priority” on Page 34). MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL 1. Press MAN. MAN appears. 2. Enter the number of the desired target channel where you want to move the frequency that is stored in the monitor memory, then press PROG. PGM appears. 3. Press MON/CLR (•) then enter the number (1–10) of the monitor memory containing the frequency. 4. Press E. The frequency transfers from the monitor memory into the selected channel. 20-524.fm Page 31 Tuesday, August 31, 1999 3:55 PM
32 SCANNING THE STORED CHANNELS To begin scanning channels, press SCAN. The scanner scans through all non-locked channels in the activated banks. (See “Locking Out Channels” on Page 34 and “Turning Channel-Storage Banks On and Off” on Page 33). When the scanner finds a transmission, it stops on it. When the transmission ends, the scanner resumes scanning. Notes: • If you have not stored frequencies into any chan- nels, the scanner does not scan. • If the scanner picks up unwanted partial, or very weak transmissions, turn SQUELCH clockwise to decrease the scanner’s sensitivity to these sig- nals. To listen to a weak or distant station, turn SQUELCH counterclockwise. • To ensure proper scanning, adjust SQUELCH until the audio mutes. • To scan in the trunk scanning mode, see “Trunking Operation” on Page 41. MANUALLY SELECTING A CHANNEL You can continuously monitor a single channel without scanning. This is useful if you hear an emergency broadcast on a channel and do not want to miss any details — even though there might be periods of silence — or if you want to monitor a specific channel. To manually select a channel, press MAN, enter the channel number then press MAN again. Or, if while scanning, the radio stops at a channel you want to listen to, press MAN one time. (Repeatedly pressing MAN at this time causes the scanner to step through the channels.) Press SCAN to resume automat- ic scanning. 20-524.fm Page 32 Tuesday, August 31, 1999 3:55 PM
33 SPECIAL FEATURES DELAY Sometimes a user might pause before replying to a transmission. To avoid missing a reply on a specific channel, you can program a 2-second delay into any channel or frequency. The scanner continues to moni- tor the channel frequency for an additional 2 seconds after the transmission stops before resuming scanning or searching. Depending on how the scanner is operating, follow one of these steps to program a delay. • If the scanner is scanning and stops on an active channel where you want to store a delay, quickly press DELAY before it continues scanning again. DLY appears. • If the desired channel is not selected, manually select the channel, then press DELAY. DLY ap- pears. • If the scanner is searching, press DELAY while the scanner is searching. DLY appears and the scan- ner automatically adds a 2-second delay to every frequency it stops on in that band. To turn off the 2-second delay, press DELAY while the scanner is monitoring a channel, scanning, or search- ing. DLY disappears. TURNING CHANNEL-STORAGE BANKS ON AND OFF You can turn each channel-storage bank on and off. When you turn off a bank, the scanner does not scan any of the 50 channels in that bank. 20-524.fm Page 33 Tuesday, August 31, 1999 3:55 PM
34 While scanning, press the number key that corresponds to the bank you want to turn on or off. Numbers appear at the top of the display, showing the currently selected banks. The scanner scans all the channels within the displayed banks that are not locked out (see “Locking Out Chan- nels”). The bank number flashes when the scanner scans the channel that belongs to the bank. Notes: • You can manually select any channel within a bank, even if that bank is turned off. • You cannot turn off all banks. One bank must always be active. LOCKING OUT CHANNELS You can increase the scanning speed by locking out channels that have a continuous transmission, such as a weather channel. To lock out a channel, manually select the channel, then press L-OUT(S/S). L/O ap- pears. Note: You can still manually select locked-out chan- nels. To remove the lockout from a channel, manually select the channel, then press L-OUT(S/S). L/O disappears. To unlock all channels in the banks that are turned on, press MAN to stop scanning, then hold down L-OUT(S/S) until the scanner beeps twice. PRIORITY The priority feature lets you scan through the channels and still not miss important or interesting calls on spe- cific channels. You can program one stored channel in each bank as a priority channel (10 for the banks in Group A and 10 for the banks in Group B). If the priority feature is turned on, as the scanner scans the bank, it checks that bank’s priority channel for activity every 2 seconds. 20-524.fm Page 34 Tuesday, August 31, 1999 3:55 PM
35 The scanner automatically designates each banks first channel as its priority channel. Follow these steps to select a different channel in a bank as the priority chan- nel. 1. Press PROG. 2. Enter the channel number you want to select as the priority channel, then press PRIORITY (H/S). appears to the right of the selected channel num- ber. 3. Repeat Steps 1 and 2 for the channel in each bank you want to program as a priority channel. To review all priority channels (in ascending order only), press PROG, then repeatedly press PRIORITY to see the numbers of the priority channels. To turn on the priority feature, press PRIORITY during scanning. PRI appears. Then the scanner checks the designated priority channel every 2 seconds in each bank. The bank number appears at the top of the dis- play. To turn off the priority feature, press PRIORITY. PRI disappears. Notes: • The priority feature must be turned off to listen to the monitor memories or to use the data skip fea- ture. • If you have locked out all priority channels, appears when you activate the priority feature. To unlock any desired priority channels, see “Locking Out Channels” on Page 34. P LOC OUt 20-524.fm Page 35 Tuesday, August 31, 1999 3:55 PM
36 USING THE KEYLOCK To protect the scanner from accidental program chang- es, turn on the keylock feature. When the scanner is locked, the only controls that operate are SCAN, MAN, KEYLOCK, VOLUME/OFF, and SQUELCH. To turn on the keylock, hold down KEYLOCK until K/L appears. To turn it off, hold down KEYLOCK until K/L disappears. Note: Using keylock does not prevent the scanner from scanning channels. USING THE DISPLAY BACKLIGHT To turn on the display light for easy viewing at night, press .The display lights for 15 seconds. To turn off the light sooner, press again. CHANGING SEARCH SPEEDS The PRO-94 has two search speeds. To switch between the normal and Hypersearch speeds during limit search or direct search, press H/S. HYPER appears during Hypersearch. Note: Hypersearch applies only to the 5 kHz step bands (29–54 MHz, 137–174 MHz, and 216–224.9950 MHz).Normal Search Hypersearch 100 steps/second 300 steps/second 20-524.fm Page 36 Tuesday, August 31, 1999 3:55 PM
37 TURNING THE KEYTONE OFF/ON 1. Turn off the scanner. 2. While holding down L-OUT/S/S, turn on the scan- ner. OFF bEEP appears. To turn the key tone back on, repeat these steps. on bEEP appears. TURNING THE BATTERY SAVE FUNCTION OFF/ON When the scanner is set to receive (monitor) a manually selected channel, and it is not actively scanning, using the battery save feature conserves energy. To turn the battery save function off or back on, turn off the scanner, then hold down PRIORITY and turn on the scanner. • OFF SAVE briefly appears when battery save has been turned off. • on SAVE briefly appears when battery save has been turned on, and appears. When the battery save feature is active, the scanner re- peatedly turns off the internal power for 1 second, then turns it back on for about 1/2 second to check for a transmission.

38 SKIPPING DATA SIGNALS To prevent the scanner from stopping on channels that consist of nonmodulated or data signals (such as fax or modem transmissions) during a search or scan, turn on the data skip feature. When the radio receives a data signal and data skip is selected, the signal is ignored. To turn on the data skip feature, turn off the priority fea- ture if it is on (see “Priority” on Page 34), then press DA- TA . DATA appears. To turn off the data skip feature, press DATA again. DATA disappears. Note: This feature does not apply to the air service band as data signals are not generally found in this ser- vice. RECEIVING NWR-SAME AND WEATHER ALERT SIGNALS In 1994, the National Oceanic and Aerospace Adminis- tration (NOAA) began broadcasting alerts that include digitally encoded data. Specific Area Message Encod- ing (SAME) includes information which identifies the se- verity of the alert. The PRO-94 displays this data as codes corresponding to the levels of severity (L1, L2, and L3). Tu r n i n g O n t h e S A M E Weather Alert Feature 1. Press SVC (E) and select the weather search mode. See “Service Bank Search” on Page 29. 2. Press ALT (DATA). This mutes the audio until the scanner receives a SAME coded signal. 20-524.fm Page 38 Tuesday, August 31, 1999 3:55 PM
39 When the scanner receives a SAME coded signal, ALERT flashes and an associated “L” code (which indi- cates the severity of the alert) appears, as well. The scanner remains on the weather channel and the audio turns on so you can hear the weather broadcast. The scanner displays one of the following codes to indi- cate the alert level. L1: Warning L2: Watch L3: Statement -----: Non-emergency In addition to weather alerts, the scanner also receives test and other event information. See “NWR-SAME Code Detection Tests” on Page 40. SAME Signal Detection Updating When the scanner receives a SAME-coded signal, it re- tains information about the most recent alert until you turn off the power. Once the scanner detects an alert code, ALERT flashes. To verify the specific alert level (L1, L2, or L3) press SVC (E) to select the weather search mode. Press ALT (DATA) to clear the alert. 20-524.fm Page 39 Tuesday, August 31, 1999 3:55 PM
40 NWR-SAME Alert Tone Test To hear and test the tones for the three alert levels, press SVC (E) to select the weather service, then hold down ALT for about 1 second. The tones sound in the order L3, L2, then L1, and TESt flashes. Each alert code appears as its tone sounds. Press any key to end the test sequence. NWR-SAME Code Detection Tests The National Weather Service sends out daily, weekly, and monthly test (and sometimes demonstration) sig- nals, which let anyone with a receiver (such as the PRO-94) verify that the equipment is working properly. To find out the specific test schedule in your area, con- tact your local NOAA or NWS office. Those offices are usually listed in the telephone book under US Govern- ment, Department of Commerce . When ALERT appears, hold down ALT (DATA) for about 1 second. The frequency and TESt appear alternately. When the scanner receives the test code, TSt also ap- pears . To exit the test mode, press ALT (DATA) for about 1 sec- ond. Note : If an actual alert is sent, the scanner sounds the appropriate tone and displays the corresponding alert level. 20-524.fm Page 40 Tuesday, August 31, 1999 3:55 PM
