The 800009 Series High Power Stationary Telescopes are available in coin and non-coin operated models. The telescopes are designed specially for outdoor installation and long distance viewing. As a result, they can be operated even in adverse weather conditions. Major adopted standards during the process of design and manufacture include GB/T17117 Prism Binoculars, GB1185 Surface Imperfections of Optical Elements, GJB1240 General Specification for Telescope, GJB150 Laboratory Environmental Test Methods for Material, MIL-STD-810 Environmental Engineering Considerations and Laboratory Tests, etc. Meanwhile, an
optical shutter system is built into the coin operated model of the series. The coin operated system is connected to this shutter system, in which the shutter will be released and hence the patron can observe through the telescope for a timed period when an acceptable coin is deposited into the coin chute. What’s more, the coin operated system is characterized by its low power consumption, electronic intelligence and long service life. The coin chute of the system can be customized to detect and accept different coins and the shutter cannot be released if an unacceptable coin is dropped into the chute. The unacceptable coin will
then be ejected automatically. The circuit of the system will automatically go into hibernation when it is idle for some time and the patron needs to drop a first coin (which will be ejected) to awaken the circuit when a beep sound will be heard. Then the shutter system can be operated again by depositing coin(s) and shutter duration will be accumulated in accordance with the number of accepted coins
