10. 注意事項  REQUIRENTS IN USE
1. 濕氣會使電極之焊錫劣質化,保持場所在溫度40℃ 以下濕度 70%以下。
   IN THE HIGH HUMIDITY SITUATION, IT WILL  MAKE THE SOLDER ABILITY
   WORST. PLEASE PRESERVE THE RESISTORS IN 40℃ ,70 RH BELOW
 2. 儘量不要打開最小包裝。
   PLEASE DON`T OPEN THE MINE PACKAGE WHEN YOU PRESERVE IT
 3. 周圍溫度高時按照負荷減輕曲線圖減少使規定用電力。
   WHEN IN THE HIGH TEMPERATURE SITUATION, PLEASE ACCORD TO THE
   PICTURE OF “POWER DERATING CURVE” REDUCE THE USE OF POWER RATING
4. 儘量不要將多個電阻並列或直列連結, 而以大電壓或大電流使用。
   YOU SHOULD AVOID THE CONNECTOR OF RESISATNCE REPLACED BY LATGE
   VOLTAGE AND POWER
5. 由於特殊塗料之故, 對外部衝極力較弱, 故注意各種處置。
   DUE TO ITS SPECIAT MATERIAL OF PAINT, YOU MUST BE CAREFUL TO
   TIS WEAK APPEARANCE
6. 洗淨後, 外膜多少會弱化, 然後自然放置後可復元其強度所以洗淨後20分鐘內不要任電阻皮
膜有任何品之接觸。
   AFTER CLEANING THE BODY, IT WILL MAKE THE FILM WEAKER. BUT IF YOU LET IT NATURE DRY WITHOUT TOUCHING OR PAINTING
   ANYTHING, THE RESISTORS WILL RECOWER ITS STRENGTH BY 20 MINUTES
 7. 電阻為發熱性零件, 所以電阻間不應相互堆積或接近其它發熱零件組合成,而防礙其散熱性。
   THE RESISTORS ARE REQUESTED NOT TO PLACE BY THE OTHER HEATING
   ACCESSORIE, WHICH WILL OBSTRUCT THEIR HEAT DISSIPATION
