Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Tips for use There is no user operable part inside this product, do not disassemble this product as it may cause fire and electric shock. Please contact our company or local dealer for inspection and repair service. Do not disassemble the unit. Failure to do so could result in fire, electric shock, or equipment damage. Do not connect or disconnect the power cord or operate the switch with wet hands or you may be electrocuted. If you notice an unusual odor, smoke or abnormal heat emanating from the unit, turn off the power immediately. Continued use may result in fire, electric shock or equipment damage. Do not use voltages outside the specified voltage (18-36V DC) range of the unit, as this may result in fire, electric shock or inoperative or even damage. Do not use this product at temperatures above 55°C or below -15°C. It may not work at high temperatures. For safety reasons, switch off the power when the unit is not in use for a long period of time. Do not switch on this product when the VHF antenna is not connected, the device transmits with high power and using it without the VHF antenna connected will easily damage the product.
