ENVIRONMENTAL CHARACTERISTICS
RESULTS OF AFTER TEST：Sensitivity difference shall be within (3 dB) and should satisfy the test described under item14 after each fllowing test. 1. APPEARANCE: Should not exist any obstade to be hammful to nomal operation: damages\ cradks\ rusts and distortions etc. 3. POLARITY: When positive voltage is appliedto the teminal marked(+), diaphragm should move to the front. 4. LOAD TEST: 0.5 W white noise is applied for 96 hours and satisfy the test listed on item05,08,14. 5. HIGH TEMPERATURE DURABILITY: After having been in a test chamber for 96 hours at the condtionof+80℃±5℃andthenlet 2 hours in a room . 6. COLD TEMPERATURE DURABILITY: After having been in a test chamber for 96hours at the condtion of 40℃ ±5℃ and thenlet 2 hours in a room. 7.
