OPERATION & MAINTENANCE GUIDE - 2 Channel Digital UHF Transmitter HOLATRON SYSTEMS, LLC 7242 Alliance Court San Diego, Ca. 92119-1522 Phone or FAX: (619) 464-2137 www.holatron.com WARNING Holatron Systems specializes in the design and manufacture of standard and custom electronic control systems where reliability and error free data communication are critical. The transmitter described in this manual is part of a system intended to remotely actuate pyrotechnic or other hazardous devices, and the components of this system have been carefully designed to minimize the possibility of accidental actuation of such devices. Holatron’s design goal is to ensure that data communication errors due to radio interference or to insufficient signal strength due to low battery, exceeding specified range, or conductive objects in signal path, will result in failure of intentional actuation rather than unintended actuation. Techniques used to achieve this design goal are described in section 1.8. Though the probability of unintended actuation is extremely small, it cannot be guaranteed to be zero. Therefore, it is important that the user not enable the receiver until all persons who might be harmed by accidental actuation are in a safe area . As a condition of purchase, the user must acknowledge awareness and agreement that utilization of this product and participation in activities utilizing fireworks, rockets, and explosives is an ultra-hazardous activity carrying implied and explicit risks of injuries and damages to the user and other participants. User assumes the risk connected with the utilization of this product and all risks of participation in the activities for which this product is sold. User acknowledges that he/she/it has the necessary and required skill, expertise, training and licensing, as may be applicable or necessary by custom, usage, trade or law, to engage and participate in the ultra- hazardous activities connected with the use, purchase, transportation, or employment of the products sold under this agreement. User acknowledges that Holatron Systems, LLC, has not and will not conduct any investigation into the skill, expertise, training and licensing, as may be applicable or necessary by custom, usage, trade or law, of the user or of user’s agents, employees and assigns, to engage and participate in the ultra-hazardous activities connected with the use, purchase, transportation, or employment of this product. User specifically agrees that Holatron Systems, LLC its officers, employees and agents shall not be liable for any claim, demand, cause of action of any kind whatsoever for, or on account of death, personal injury, property damage or loss of any kind resulting from or related to user’s or user’s employees’, agents’ or assigns’ use of this product, and user agrees to indemnify, defend in any action at law, and hold harmless Holatron Systems, LLC, from same, whether brought by the user, user’s agent, or assigns, or any third party. Usage of this transmitter is authorized under FCC Rules and Regulations as listed in 47 CFR Ch.1 (10-1-96 Edition), part 15, subpart C, sections 15.209 and 15.231. Any changes or modifications to the hardware not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This manual is divided into two sections. The first is a description of the system hardware. The second covers the recommended operating and maintenance procedure. 1.0 HARDWARE DESCRIPTION. The model RFLS-1XT Two Channel Digital UHF Transmitter is a low power two channel, safety locking, hand-held remote control transmitter with a guaranteed range of 60 yards (line of sight operation) when used with the Holatron model RFLS-1RC receiver. A range of 100 yards is typical. The two channels are digitally encoded and amplitude modulated on a single carrier frequency of 418MHz. This frequency is controlled by a SAW (surface acoustic wave) device for exceptional stability. No alignment or tuning procedures are ever required to maintain optimum performance. The modulated RF output occurs continuously while one of the two momentary transmit buttons is depressed. Receiver output is continuous while this signal is being transmitted. A digital code amplitude modulates the carrier to indicate to the receiver which of the transmit buttons is depressed. The user has access to the following components: 1.1 THE ANTENNA. The RF signal is radiated by a quarter-wave flexible whip antenna which screws onto the top end of the transmitter box. The transmitter should never be operated without this antenna in place, as damage to the RF components could result. Such operation will void the warranty. Be careful not to overtighten the antenna when screwing it on, as this could cause its mating connector to rotate and break its internal connection. Overtightening could also cause the connector to rotate, with the same result, when subsequent removal of the antenna is attempted. The recommended way to install the antenna is to grasp it by its small diameter upper part and rotate gently in a clockwise direction until increased resistance is felt. It need not be tight to achieve a good electrical connection. When removing the antenna for storage, observe the base of the mating connector to ensure that it is not rotating. If the antenna is so tight that rotation is occurring, grasp the hex base of the mating connector with long nose pliers, and then unscrew the antenna. 1.2 THE SAFETY LOCKING SWITCH. The Safety Locking Switch is a miniature cylindrical keylock with two positions, “Safe” and “Xmtr Enabled”. In the “Safe” position no RF output occurs even if a button is pressed. In the “Xmtr Enabled” position modulated RF output occurs continuously while a button is pressed. Whether transmitting or not, a red warning indicator near the switch flashes whenever the switch is in its “Enabled” position and the battery voltage is above the low battery detect threshold. …
