After any tests, the sensitivity to be within ±3dB of intial sensitivity after 6 hours of conditioning at +25℃ 经测试后麦克风，需静置于 +25℃(室温)环境中 6 小时 后, 测试其灵敏度与原灵敏 度差异不得超过±3dB.
Each Con. Mic. contains a FET within its case. Generally, semiconductors are easily weakened by over-heating, over-charge of voltage. Special caution is needed for proper soldering as follows: 1. Use 15W-20W soldering iron and maintain 270℃-330℃ in operation. 2.Soldering should be accomplished within two seconds at each terminal so as not to be overheated. 3. Do not make a cavity at the surface of lead on the pattern plate. (A cavity may change the characteristics of Con.Mic.) 4. Heat Sink
