Matter on caution when installed ( assembly ) 16. 1) It should be installed deeply considered in noisy place because wrong operation might be occurred. Make sure of power source before operating after being assembled module. Damage may be occurred by low voltage or short circuit. The module is not waterproofed. so, do waterproof treatment to instrument if you need. Please install module within guaranteed scope and specially escape installation from circumstance of smoke, dust, and SO2-GAS. Please turn off power source if there is no data transmission when you testing its operation after installation. Please establish policy of heat release and use it under circumstance within guarantee scope in case a lot of module is assembled and used. In case it is used under below zero circumstance, it is favorable to use it with high voltage within maximum extent of value of input power source. Please make instrument after examining weight fully as module weight is 225g. Matter of reference when handling. 1) Over voltage prevention circuit is built in "LED POWER SUPPLY (Vcc2)" of module and LED will be turned off in case high voltage is supplied beyond maximum extent of regular power. Switch of brightness adjustment use is adjusted in fixed rank by LOT and supplied therefore don't operate it as you please. Operating circuit is composed of CMOS, so, please take caution for static electricity. If you have any question for using this, please contact us. 1999. 10. 181999. 10. 18 Product warranty Warranty contents Exchange without compensation will be made for the period of 12 month after having been delivered in case troubles in ordinary treatment in occurred.
