1 T T A A B B L L E E O O F F C C O O N N T T E E N N T T S S Page 1. INTRODUCTION The Alpha 580 is highly reliable industrial remote control system. The versatile features of the Alpha 580 permit its use in many different remote control applications. The system can be used to control cranes, hoists, trolleys, mining equipment, building construction equipment, automatic control systems, and many others. The Alpha 580 radio control system incorporates numerous redundant safety circuits that guaranty maximum security and ensure the system is resistant to outside interference. The major features of the Alpha 580 are as follow: * The system uses advanced microprocessors which utilizes highly evolved software that have redundant error checking and correcting capabilities to ensure 100 % error-free transmission, decoding, and control of the output relays. These highly evolved software include CRC (Cyclic Redundancy Check codes) and Hamming Codes. * To insure maximum operating safety, the Alpha 500 series incorporate many safety features. Some of these safety features include receiver self-diagnosing, transmitter pushbutton self-diagnosing, transmitter low voltage detection/warning, and transmitter/receiver auto shutdown after 1 minute of transmitter low voltage warning. * The encoder/decoder system utilizes advanced microprocessor. The availability of 32,768 sets of unique ID codes will ensure that only commands from the matching control transmitter can be carried out without any interference from other radio systems. A special programmable integrated circuit is used to insure the unit can not simultaneously command conflicting movements. * Full SMT design for system stability. The Alpha 580 radio control system consists of a transmitter handheld, and a receiver unit. The transmitter casing is molded using an industrial strength composite material which is impervious to dust, water, oil, acids, alkaline, heat, sunlight, and as well as being resistant to deformation due to long term use in harsh environments. The pushbuttons are also constructed from industrial strength composite material with a minimum of up to one million cycles. For power saving, the transmitter unit uses special high efficiency power saving circuits that requires only two “AA” alkaline batteries (UM-3). 3 2. SAFETY INSTRUCTION The Alpha 580 system is relatively simple to use. However, it is very important to observe the proper safety procedures during operation. When use properly the Alpha 580 system will enhance productivity and efficiency in the workplace. The following instructions should be strictly followed: 1. Make a daily check of the transmitter casing and pushbuttons. Should it appear that anything could inhibit the proper operation of the transmitter unit, it should be immediately removed from service. 2. The transmitter voltage should be checked on a daily basis. If the voltage is low, the two "AA" alkaline batteries should be replaced. 3. The emergency stop pushbutton (EMS) should be checked at the beginning of each shift to ensure they are in the proper working order. 4. In the event of an emergency, activate the emergency stop pushbutton immediately. Then turned the power “off” from the main power source of the equipment. 5. The power switch should be turned “off” after use and should never left the power “on” when the unit is unattended. 6. Do not use the same RF channel and ID code as any other unit in use at the same facility. 7. Ensure the wrist strap is worn at all time during operation to avoid accidental dropping. 8. Never operate a crane or equipment with two (2) transmitter units at the same time with same RF channel and ID code. 4 3. PUSHBUTTON CONFIGURATION The Alpha 580 model can be configured from 3 to 5 motions with 2-speed pushbuttons and an emergency stop button (EMS).

Alpha 580 Model Operational Description The Alpha 580 industrial radio remote control system consists of a pushbutton type transmitter unit that operates on two (2) “AA” size alkaline batteries (3 volts) and a receiver unit that is hooked up to AC 115V voltage input. The receiver also provides a terminal output for connection to Ground. The receiver unit is also equipped with an Arial Antennal that operates on 433MHZ range. The receiver unit is hooked up on to an industrial crane system with numerous travel directions and speeds via electrical motors. The output relays in the receiver is rated at 212DC @ 10A. By pressing the pushbuttons on the transmitter unit will able the contact relays inside the receiver box to energize, thus activate the magnetic contactors inside the crane control panel. When the transmitter pushbutton is pressed, the encoder board will encode the information and then sends it out to the receiver unit via the transmitting circuitry. The receiving module inside the receiver unit then receives this transmitted information. Afterward it sends the received information to the decoding microprocessor for decoding process by numerous software programming (CRC and Hamming code bit checking). After decoding process is completed, the central microprocessor will then enable the intended contact relay or relays to energize. The receiver unit also equipped with double MAIN contact relays. When the transmitter unit is not in use, these two MAIN contact relays will be disengaged thus provide no power to the receiver unit.

In addition, the requirements of section 15.35 for averaging pulsed emissions and for limiting peak emissions were met. The field strength of harmonic and spurious emissions did not exceed 1,097 μV/M (AVERAGE). 15.231 (c) -The device operates at 433.25 MHz. The bandwidth of emissions did not exceed 0.25% of the operating frequency (1.1 MHz). DETERMINATION OF FIELD STRENGTH LIMITS The field strength limits shown below are found in Section 15.231. Frequency Limit F1=2603750=L1 Fo=433Lo F2=47012500=L2 The formula below was utilized to determine the limits: Limit = L1 + [(Fo-F1)(L2-L1)/(F2-F1)] Solving yields: Fundamental Limit= 10,970 μV/M (AVERAGE) @ 3 Meters Harmonic Limit= 1,097 μV/M (AVERAGE) @ 3 Meters Retlif Testing Laboratories R Test Report No. R-8882-1 FCC ID: LZ6ALPHA510SERIES REPORT OF MEASUREMENTS (continued) DETERMINATION OF DUTY CYCLE The unit’s RF output was directly coupled to the input of the spectrum analyzer. The analyzer was set for a frequency span of 0Hz. The sweep time was then adjusted in order to display one full pulse train. The transmitter on time was then summed and compared to the time for one full cycle in order to obtain the duty cycle. (See plots for additional information) Transmitter On Time=75.67 milliseconds (maximum- worst case in 100 ms) Transmitter Cycle Time=Greater than 100 milliseconds Transmitter Duty Cycle=75.7 % SPECTRUM ANALYZER DESENSITIZATION CONSIDERATIONS Due to the nature of the emissions being measured, care was taken to ensure that the resolution bandwidth of the spectrum analyzer was adequate to provide accurate measurements. The following formula was utilized: Setting pulse desensitization equal to zero and utilizing the minimum observed pulse width of 75.76 milliseconds yields a minimum required bandwidth of 8.8 Hz. FCC specified bandwidths of 100kHz and 1MHz were utilized below and above 1GHz, respectively. Retlif Testing Laboratories R Test Report No. R-8882-1 FCC ID: LZ6ALPHA510SERIES REPORT OF MEASUREMENTS (continued) GENERAL NOTES 1.All readings were taken utilizing a peak detector function at a test distance of 3 meters. 2.The duty cycle was applied to the peak readings in order to determine the average value of the emissions. 3.All measurements were made with 3 VDC derived from 2 “AA” batteries. 4.The frequency range was scanned from 30 MHz to 4.3 GHz. All emissions not reported were more than 20 dB below the specified limit.
