Model EASy-PLUS® Emergency Alert System Encoder/Decoder User’s Manual P/N 0010224001 TRILITHIC Rev 1.02 EASy-PLUS® User Manual –1 Trilithic Incorporated’s latest innovation for your Emergency Alert System is the EASy-PLUS ® Encoder/ Decoder. The fully featured E.A.S system, highlighted by the EASy-PLUS ® Encoder/Decoder was designed with the smallest of cable systems in mind, and can handle a system serving 100 subscribers as well as systems handling over 2,000,000 subscribers. With Trilithic’s embedded DSP technology and manufacturing, standard features such as FLASH BIOS will guarantee that your EASy-PLUS ® platform will never go out of style. Periodic updates to the platform are handled with the ease of a simple download from our WEB site. No more disassembly just to change proms or software. With Trilithic’s EASy-NET® option, a simple phone call from your desktop PC to any one of your remote headends, allows you to retrieve the last 100 E.A.S. events from nonvolatile memory for logging and printing at your office. You’ll never miss your FCC required logging because of printer failures, paper jams or lack of paper. Innovations such as built-in AM/FM/NOAA selectable tuners, automatically generated and programmable FCC weekly testing, remote hub-site transmitter, and complete Motorola® digital platform compliance, truly makes this your Emergency Alert System of choice. The EASy-PLUS ® has the following standard and built-in, features and benefits: § EASy-PLUS ® enables parsing of F.I.P.S. codes The new Trilithic EASy-PLUS ® encoder/decoder distributes individual analog E.A.S. messages structured for, or earmarked for, one specific community or up to sixteen (16) communities located within multi-trunk output headends. § Flash BIOS Trilithic’s new EASy-PLUS ® encoder/decoder eliminates the need to remove the unit from the rack, pull the cover or lid and change or upgrade chipsets and proms. Government-regulation modifications or changes, new programming, additional advancements, and many other new features, can easily be handled through a simple upload via the WEB. § Programmable RWT (Required Weekly Test) for Automatic Triggering This feature allows your E.A.S. system to automatically generate a random RWT event, once, within each seven (7) day window, satisfying the FCC requirement for cable systems generating and logging their own weekly test. § Stores the most recent 100 emergency alerts A nonvolatile Emergency Alert Storage System eliminates the need for attaching a printer at the headends’ encoder/decoder to view the most current alerts or events. A continuous update of the last 100 E.A.S. events triggered through Trilithic’s EASy-PLUS ® encoder/decoder can be downloaded via a PC at the headend, or through the optional EASy-NET® telephone interface anywhere in the country. E.A.S. events can easily be archived and/or printed on an external dot-matrix printer at the customer’s convenience. Logfile is word-processor compatible. § Two (2) internal radios that are each tunable as AM, FM, or NOAA radios This means you will not have to purchase any additional radios to meet the FCC requirement of LP-1 and LP-2 monitoring stations. Simply tune each of the two radio receivers to either AM or FM, to match the designated LP-1 and LP-2 stations assigned for your area, or the NOAA frequencies if so needed. Dual cards can be installed giving four (4) internal radio selections. § Four (4) external radio inputs for added monitoring capabilities This feature allows you to meet the requirements dictated by some State Emergency Management Plans that may require a possible third, fourth or more monitoring selections. § Remote hub-site insertion transmitter is included as standard equipment An internal AFSK TX transmitter is included as standard equipment in the new EASy-PLUS ® encoder/ decoder. This transmitter eliminates all external remote TX components of earlier E.A.S. systems. EASy-PLUS® User Manual 2– TRILITHIC Rev 1.02 The AFSK TX transmitter is self-contained, and includes audio switching capabilities for “tune-to” audio distribution and remote hub-site support via Trilithic’s Virtual Controller. § Three (3) Programmable dry-contact-closure relays These programmable relays can be conveniently used for directly driving comb generators, Motorola® OM1000(s) for digital E.A.S., and multi-vendors distribution switches. § Audio D/A outputs Four (4) outputs are included on the EASy-PLUS ® encoder/decoder allowing for simple audio distribution utilizing all technologies of switching. § Latest DSP Technology Trilithic’s use of Digital Signal Processing provides the most current engineering and manufacturing processes available. § EASy-Plus Setup Program The simple, user-friendly setup program walks you through the entire system setup easily, upon initialization.

The encoder/decoder is a fully selfcontained system, which includes a NTSC video character generator output, multiple balanced audio outputs, audio and video switching, 100 message queue, speaker and microphone, two internal AM/FM/NOAA radios and four programmable contact closures used for such things as OM-1000 digital switching. The EASy-PLUS ® E.A.S. Encoder/Decoder is a two-U rack mounted control center capable of performing manual or automated EAS messaging for cable Headends and Hub sites, in accordance with CFR 47 part 11 FCC regulations, and the EAS Cable Handbook. The EASy-PLUS® receives E.A.S. messages from up to six audio sources (internal or external), decodes the message, and operates Cable System equipment to replay the message for subscribers. In addition, messages can be originated by the user via local or remote control of the EASy-PLUS®. The E.A.S. audio sources for the EASy-PLUS® include internal AM/ FM/NOAA radios and external audio inputs that can be connected to any known E.A.S. audio source. E.A.S. audio is decoded by the internal AFSK circuitry, sorted, and then interpreted to determine the type of emergency or test. The locations codes for which the emergency applies, and other information supplied in the E.A.S. header are also decoded. If a voice message is contained in the E.A.S. message, it is recorded for playback to subscribers. E.A.S. messages then pass through a series of tests to determine if the message matches predefined, user configurable filters and parameters for your location. E.A.S. activation of the cable system then automatically occurs. To play an E.A.S. message to your subscribers, the EASy-PLUS® activates TTL drivers and Contact Closures, as well as sending commands via RS-485 and High Data Rate AFSK. The EASy-PLUS® also supplies pertinent video and re-encodes and plays the E.A.S. FSK header and recorded audio. The TTL drivers, Contact Closures, and RS-485 commands activate your interface equipment (i.e. I.F. switching, comb generator, baseband character generators) throughout the headend to provide the emergency audio and video to all channels of the cable system. In addition to the E.A.S. messaging capabilities, the EASy-PLUS® logs all received and transmitted messages to a printer, the LCD display, and it’s internal log storage area. The EASy-PLUS ® has an optional dial-in telephone interface and a unique remote feature using EASy-NET ® optional software for remote control of the entire system. Using the EASy-NET ® software, the operator can generate any event code and header by simply clicking on the list of events. Prerecorded, or live audio can also be added to the event. FLASH-BIOS is used to update the EASy-PLUS ® nonvolatile memory, programming, and FCC event codes list. The EASy-PLUS ® encoder/decoder has the ability to parse FIPS codes out to individual counties or areas in conjunction with the appropriate wiring architecture of the cable headend. This keeps the interruptions to a minimum for customers not affected by the alerted area. Trilithic’s unique AFSK transmitter card comes standard in the system. The AFSK signal alerts Trilithic’s downstream Virtual Controllers to perform channel insertions at remote hubs, OTNs, and headends for channels not originating at the master headend. The EASy-PLUS ® encoder/decoder can handle cross-county applications as well as cross-state-line scenarios. Multiple states and counties can easily be added with a click-of-the-mouse. 1.2 UNPACKING AND INSPECTION When your system arrives, immediately inspect its shipping container and contents for visible damage. Keep all packing materials until equipment performance has been confirmed. If any of the equipment is damaged or fails to operate properly due to transportation damage, file an immediate claim with the transportation company or, if insured separately, with the insurance company. The EASy-PLUS ® encoder/decoder may, or may not, arrive in a single shipping container. If it arrives in its own container, the EASy-PLUS ® is a completely self contained system.

The EASy-PLUS® encoder/decoder is the device which, when radio station signals are supplied to its internal radios, decodes Emergency Alert System header information when monitoring your (local primary) LP-1 and LP-2 stations, and optionally, your National Weather Service radio signals (on NOAA frequencies 162.400 MHz (WX2), 162.425 (WX4), 162.450 (WX5), 162.475 (WX3), 162.500 (WX6), 162.525 (WX7), 162.550 (WX1). Your LP-1 (local primary one) and your LP-2 (local primary two) radios are usually an FM and AM radio station, respectively. These radio stations are assigned in your state emergency plans, usually available on the home WEB site for your state. Your state plan should detail how your entire state emergency alerting system functions, including your assigned (SP) state primary frequencies and transmitter locations. Your LP-1 and LP-2 broadcasters typically have the obligation to pass through to your encoder/decoder the EAN (that’s the Emergency Action Notification-the presidential message) and the RMT (the Required Monthly Test). You will also receive RWT (Required Weekly Tests), which you may, or may not, be required to pass on to your cable system headend. You are required to perform your own locally generated RWT, which can be done from the front keypad, remotely via a telephone, or by using the random RWT generator built into your EASy-PLUS® system. Your EASy-PLUS® encoder/decoder is the first piece of equipment to receive the alert from your monitoring stations. It will decode the signal, format the message into an NTSC video signal (standard analog format) and present this video to its output port (CG VIDEO OUT). Depending on whether you’ve looped your “designated E.A.S. channel” video through the CG VIDEO IN, your E.A.S. will either crawl over incoming video, or crawl over an internally generated full-screen E.A.S. page. The E.A.S. alert audio associated with the message is also available at the rear connector and is distributed to either your I.F. switching interface or your comb generator, just as the video output is distributed to these same interfaces. For remote hub site channel insertions downstream, your EASy-PLUS® has a built-in AFSK in-band data generator for signally Trilithic’s remote headend/hub site Virtual Controller. The V.C. is used for multiple applications at remote hub sites for performing channel insertions, remote OM-1000 control for force-tuning Motorola settops during an E.A.S. alert as well as many other off-site applications. The FCC requires logging of all incoming E.A.S. events and tests. This is accomplished by applying a customersupplied parallel printer (non-Windows driver based) to the DB-25 parallel printer port at the rear of the EASy-PLUS® system. Visit WWW.TRILITHIC.COM and click on EAS DIVISION to view or download manuals on all of Trilithic’s E.A.S. products. 2.2 FRONT PANEL The EASy-PLUS® front panel contains four items. Perforated holes for the internal microphone. Perforated area for the internal speaker. LCD display 16 button keypad The keypad is used for rudimentary setup at the cable headend and for initiating the Required Weekly Test. Most setup features are programmed using the SETUP program provided with each EASy-PLUS® encoder/decoder. ENCODER Initiating E.A.S. events (other than the RMT and RWT) is accomplished using the SETUP software. Activation of events will be covered in the software setup section of this manual. DECODER The decoder is an automated mechanism used to decode incoming E.A.S. messages via the baseband radio input signals to the microprocessor. 2.3 BACK PANEL RS-232 COM1 COM2 Used for uploading setup data from PC or Laptop. Future Use. PARALLEL PORT: Used for connecting a standard (EPSON emulation) parallel printer for FCC mandatory logging of all incoming E.A.S. events and tests. CG VIDEO: EASy-PLUS® User Manual 10 – IN: Connect “designated E.A.S. channel” video, (your tune-to channel), to CG VIDEO IN, if and only TRILITHIC Rev 1.02 if, you plan to use a video distribution amplifier at the CG VIDEO OUT to distribute the video back to your tune-to modulator as well as to your comb generator. NOTE: This is done only if you plan to use a “tune-to” video and audio message supplied to your comb generator prior to running the alert on your “designated E.A.S. channel”. This will be explained further in the applications section of this manual. OUT: Connect CG VIDEO OUT to the input of your I.F. source modulator or to your comb generator. If you are using an external video D/A, connect to input of D/A and then connect one output to your comb generator and one output to your “designated E.A.S. channel” video input. AUDIO EXPANSION 1: Ch 1: AM or FM or NOAA radio antenna input. Ch 2: AM or FM or NOAA radio antenna input. AUDIO EXPANSION 2: Ch 3: AM or FM or NOAA radio antenna input. Ch 4: AM or FM or NOAA radio antenna input. RS-485: 2.4 For use with Trilithic external character generators, remote Virtual Controllers. TERMINAL CONNECTOR: TTL OUTPUTS: The individual programmable outputs which switch between TTL levels of 0 and 5 vdc. Each output is programmable for switching with full system substitution timing, “designated E.A.S. channel” substitution timing or “designated E.A.S. channel” audio-only switch timing. These outputs are generally attached to the I.F. switching component (the LS-16P) or the baseband switching component (the SW-8). This will be explained in more detail in the headend applications section. CONTACT CLOSURES: Used to connect such devices as a comb generator activation and Motorola OM-1000 Red/Black terminals for digital settop force-tuning. AUDIO OUTPUTS: E.A.S. alert audio is presented at all four audio outputs. Use these outputs to connect to E.A.S. distribution equipment such as I.F. source modulator or comb generator. AUDIO INPUTS: One extra set of baseband audio inputs used as audio input source #5 & #6 for monitoring stations. AFSK SWITCH: Loop through baseband audio path from a modulator (usually your “designated E.A.S. channel) to send AFSK tones downstream to the remote hub site Virtual Controllers. AUDIO SWITCH: Input - Route the “designated E.A.S. channel” audio through for baseband control of “tune-to” channel. Used usually in conjunction with an external video D/A. See applications section for further information. Output - Route the “designated E.A.S. channel” audio through for baseband control of “tune-to” channel. Used usually in conjunction with an external video D/A. See applications section for further information. The INPUT/OUTPUT switch timing correlates to the E.A.S. channel substitution.

TRILITHIC Rev 1.02 EASy-PLUS® User Manual – 19 EASy-PLUS® User Manual 20 – TRILITHIC Rev 1.02 SECTION 6 EASy-PLUS ® Encoder/Decoder Installation and Wiring 6.1 INTRODUCTION The EASy-PLUS ® receives E.A.S. messages from up to six audio sources (internal or external), decodes the message, and operates Cable System equipment to replay the message for subscribers. In addition, messages can be originated by the user via local or remote control of the EASy-PLUS ®. The E.A.S. audio sources for the EASy-PLUS ® include internal AM/FM/ NOAA radios and external audio inputs that can be connected to any known E.A.S. audio source. E.A.S. audio is decoded by the internal AFSK circuitry, sorted, and then interpreted to determine the type of emergency or test. The locations codes for which the emergency applies, and other information supplied in the E.A.S. header are also decoded. If a voice message is contained in the E.A.S. message, it is recorded for playback to subscribers. E.A.S. messages then pass through a series of tests to determine if the message matches predefined, user configurable filters and parameters for your location. E.A.S. activation of the cable system then automatically occurs. To play an E.A.S. message to your subscribers, the EASy-PLUS ® activates TTL drivers and Contact Closures, as well as sending commands via RS-485 and High Data Rate AFSK. The EASy-PLUS ® also supplies pertinent video and re-encodes and plays the E.A.S. FSK header and recorded audio. The TTL drivers, Contact Closures, and RS-485 commands activate your interface equipment (i.e. I.F. switching, comb generator, baseband character generators) throughout the headend to provide the emergency audio and video to all channels of the cable system. In addition to the E.A.S. messaging capabilities, the EASy-PLUS ® logs all received and transmitted messages to a printer, the LCD display, and it’s internal log storage area. 7.2 INSTALLATION AND WIRING OF THE EASY-PLUS ® ENCODER/DECODER Typical installation of the encoder/decoder requires the operator to attach radio antenna inputs at the Audio Expansion 1 coaxial input connectors, attach AUDIO and CG VIDEO Outputs to either an I.F. source modulator or audio input to a comb generator, and attach either TTL control line output to I.F. switching devices or a contact-closure output to the comb generator. Optional control of the Motorola OM-1000 QPSK modulator is accomplished by using a secondary contact-closure attached to the red and black terminals at the rear of the OM-1000. 7.3 PINOUT DESIGNATIONS AT THE REAR PANEL OF THE EAS-yPLUS ® ENCODER/DECODER. asf TRILITHIC Rev 1.02 EASy-PLUS® User Manual – 21 Parallel Port TRILITHIC EASy PLUS FCC ID P4V-EASY-PLUS-1 G C1 NO1 NC1 C2 NO2 NC2 C3 NO3 C4 NO4G CG VIDEO IN OUT Contact-Closure Wires to Connect to Red & Black Terminals of OM-1000 Contact-Closure Wires to Connect to Comb Generator REAR PANEL EASy-PLUS ® Balanced Audio Output for Comb Generator or I.F.

TRILITHIC EASy-PLUS® Encoder/Decoder for Emergency Alert Systems TRILITHIC Rev 1.02 SECTION 7 I.F. (Composite I.F., Aux. I.F., Single I.F.) INTERFACE and INSTALLATION 7.1 INTRODUCTION Single I.F. Replacement Composite I.F. (both visual and aural intermediate carriers on the same coaxial cable) replacement is a technique which is used to change the program content on a channel without altering the RF output carrier frequency or amplitude. With this technique you will need to install an I.F. switch in the composite I.F. loop-through on the rear of the modulator or processor housing (i.e. the channel’s rack mount assembly). Generally, modulators have this I.F. loop on the back of the housing. In some cases, you may be able to install the loop into the housing to implement this type of switching. For the E.A.S. application, the alternate I.F. signal will be taken from an independent distribution system which will be explained as you move through this manual. Single (Composite) I.F. Switch Installation (SW-1) The first step when assembling the E.A.S. system is to install an SW-1 or SW-4 switch on the rear of each modulator or processor. The SW-1 is a three terminal device used to substitute the current I.F. source with an alternative I.F. source. The SW-4 switch is a two terminal device with a terminal strip localize as a contact-closure for such chassis as the S-A Continuum modulators and processors. I.F. signal fed from the LS-16P Lossless Splitter EAS IN TRILITHIC I.F. OUT I.F. SW-1 Normal I.F. OUT fed to the I.F. IN of the modulator or processor Normal I.F. IN fed from the I.F. OUT of the modulator or processor For each SW-1 installed, you will need two (2) 75 Ohm cables of equal length about three (3) to six (6) inches in length. The next step will cause a brief interruption of the channel involved while the I.F switch is being connected, but the signal will return once the switch is installed. Connect the 75 Ohm cable from the I.F. OUT of the modulator or processor to the I.F. IN of the SW-1 switch. Connect the I.F. OUT of the SW-1 switch to the I.F. IN of the same modulator or processor. See the following diagram. You will TRILITHIC Rev 1.02 EASy-PLUS® User Manual – 23 connect the EAS IN at the SW-1 switch later in this procedure. Repeat this procedure on all modulators and processors that have a composite I.F. loop-through on the rear of their housing. 7.2 Selecting a “Designated E.A.S. Channel” at I.F. You will assign one channel on the cable system as the “Designated E.A.S. Channel”. This is the channel on which all E.A.S. alerts and messages received via your Local Primary monitoring stations (i.e.: AM, FM, or NOAA) will be displayed. Depending on installation techniques used, these messages and alerts will appear in the form of a gen-locked crawl message over either the existing video or over a full page blue background. Selecting a low priority channel (one which is not trapped or scrambled as it enters every home on the system) as the “Designated E.A.S. Channel” is optimum. Generally, a community access channel, government channel, or character generator channel in the VHF television band (i.e.: ch. 2-13) is ideal to use for the “Designated E.A.S. Channel”. NOTE: 7.3 IN ALMOST ALL INSTANCES A MODULATOR WITH A COMPOSITE I.F. LOOP WILL BE USED FOR THE “DESIGNATED EAS CHANNEL”. THERE ARE EXCEPTIONS, SUCH AS BASEBAND OR CHARACTER GENERATOR EAS SYSTEMS OR COMBINATIONS OF BASEBAND AND I.F. SYSTEMS. THESE EXCEPTIONS WILL BECOME APPARENT IN EACH INTERFACE SECTION OF THIS MANUAL. LS-16P Lossless Splitter Placement and Connection The LS-16P is a precision I.F. distribution amplifier (D/A) which has a 20dB continuously variable precision attenuator for I.F. alignment on each of its 16 output connections. The LS-16P is also used to insert a DC drive voltage on the output drop cable’s center conductor for activating each SW-1 or SW-4 switch, as well as other LS-16P input connections when the EAS system is activated. For most applications, multiple LS-16P(s) will be needed. In all installations, the first LS-16P, which receives its input EASy-PLUS® User Manual 24 – TRILITHIC Rev 1.02 from the I.F. source modulator, should be labeled by the customer as the “Primary LS-16P”. Any other Primary LS-16P output port may be used to drive Secondary LS-16P(s) input ports or SW-1 and SW-4 switches. For example, in a typical headend of 46 channels you will need three (3) LS-16P(s). One LS-16P will serve as the Primary and the two (2) remaining LS-16P(s) will serve as Secondaries. Total channel capacity will be twelve (14) ports from the Primary LS-16P, with the remaining two (2) ports of the Primary feeding two (2) Secondary LS-16P(s). Two (2) times sixteen (16), or thirty (32) ports from the Secondary LS-16P(s) added to the fourteen (14) ports leftover from the Primary LS-16P totals 46 ports. As shown in the following diagram, one (1) LS-16P will serve up to sixteen (16) remotely located SW-1 and/or SW-4 equipped modulators and processors and/or Secondary LS-16P(s). When installing the LS-16P, place in bays or racks where their distribution coverage will be maximized. See the following diagrams.

Switch Installation (SW-4) The SW-4 switch is used to locally activate a contact closure on the rear of a modulator or processor enabling the internal I.F. switch built into the chassis. The E.A.S. I.F. signal and DC current are fed to the input port of the SW-4 switch from the LS-16P. The signal passes through the switch to the Aux. I.F. Input port on the rear of the modulator or processor. The DC current is blocked at the input to the SW-4 and converted to a normally open (N/O and N/C) contact closure. The N/O terminal of the SW-4 should be attached to the rear of the modulator on the appropriate screw terminal to cause the internal I.F. switch to activate when the LS-16P distribution system sends its signal to the SW-4. The ground terminal on the SW-4 should also be attached to an appropriate grounding point on the modulator or processor. EASy-PLUS® User Manual 26 – TRILITHIC Rev 1.02 7.5 Single (Composite) I.F. Source Modulator Installation (IFS-3) The I.F. modulator receives its video signal from the CG VIDEO OUT at the rear of the EASy-PLUS® and audio from the terminal strip and modulates these signals onto I.F. subcarriers. Once the IFS-3 source modulator is mounted, connect the RF OUT port to the I.F. IN port on the Primary LS-16P. 7.6 Precision I.F. Level Alignment of the LS-16P Lossless Splitter The LS-16P was designed for precision I.F. output level adjustment. In most instances, different modulators or processors require different I.F. input levels to maintain proper RF output levels due to the absence of an AGC at the I.F. stage. It is imperative that the headend maintain the same R.F. output level on each channel during an entire E.A.S. sequence of events. When alternate I.F. levels match those I.F. levels which are currently present at the rear of the modulator or processor, system wide stability of the trunk amps, pilot carriers, slopes, R.F. levels and scrambling systems will be maintained. DC power is delivered through the coaxial cable’s center conductor to enable the Secondary LS-16P(s), the SW-1(s), and the SW-4(s) switches. CAUTION: DO NOT INSTALL FIXED OR VARIABLE ATTENUATOR PADS IN THE INPUT OR OUTPUT CABLES OF ANY LS-16P LOSSLESS SPLITTER. ELECTRICAL SHORTING OF THESE DEVICES MAY OCCUR. The I.F. alignment procedure consists of setting the output level of the I.F. source modulator and then setting the output levels on the Primary and Secondary LS-16P(s) for proper I.F. levels at the rear of the modulators and processors. The Master Gain on all LS-16P(s) is factory set to unity gain. This adjustment should not need to be reset. Each 20dB potentiometer on the front panel of the LS-16P is factory set to 0 dB loss (i.e.: 42 dBmV output on each port of the LS16P if the IFS-3 is set to 42 dBmV output.) The test point on the front panel of the LS-16P(s) is to check for signal presence ONLY. No test alignment measurements should be made at this test point. 7.7 Procedure for precision I.F. Alignment: 1. Set the output level of the I.F. source modulator to maximum and then pad its output down to 2 dBmV higher than the highest I.F. level on your modulators/processors (typically 32-42 dBmV). Set the audio carrier level 13-17 dBmV down from the video carrier. 2. Turn all J1 - J16 dip switches on the front panel of the Primary LS-16P to OFF (disabled), except for those dip switches which control the feeds of the Secondary LS-16P(s) INPUTS. These dip switches will remain ON (enabled) at all times. 3. Enable the I.F. alignment mode in the menu system of the EASy-PLUS ® encoder/decoder. 4. Using a spectrum analyzer or field strength meter connected to the trunk line test point, identify the channel under alignment. 5. If applicable, be sure to disable any I.F. AGC switches on all modulators in the headend under I.F. alignment. 6. Looking at the channel under alignment on the spectrum analyzer or field strength meter, note the output level. 7. Turn the dip switch ON (enable) for the channel under setup, ONLY. This will enable the SW-1 or SW-4 switch at the rear of the modulator or processor under setup. You should now see the “I.F. Alignment Screen” appear on the television on the channel under test channel. 8. Using the respective potentiometer J1 - J16 on the front of the LS-16P for the channel under alignment, turn the potentiometer counterclockwise until the exact R.F. output level is achieved on the spectrum analyzer or field strength meter. 9. Turn the appropriate dip switch back OFF (disable) on the LS-16P. 10. Proceed to the next channel and repeat steps 4 through 10 until all channels are aligned. 11. Turn the I.F. AGC(s) ON for all modulators. 12. At the keypad of the EASy-PLUS unit, take the menu system out of I.F. alignment. 13. Turn all dip switches ON (enable). CAUTION: The EAS system will not trigger in the automatic mode for an EAS alert while the system is in the “I.F. Alignment” mode. You have now completed the composite precision I.F. alignment procedure.
