2-Track Recorder/Reproducer
2 轨录音机/再现器

The guarantee of performance that we provide for the 32 must have several restrictions. We say that the recorder will perform properly only if it is adjusted properly and the guarantee is that such adjustment will be possible. However, we cannot guarantee your skill in adjustment or your technical comprehension of this manual. Therefore, Basic Daily Setup is not covered by the Warranty. If your attempts at internal adjustments of such things as rebias and record EQ trim are unsuccessful, we must make a service charge to correct your mistakes. Recording is an art as well as a science. A successful recording is often judged primarily on the quality of sound as art, and we obviously cannot guarantee that. A company that makes paint and brushes for artists cannot say that the paintings made with their products will be well received critically. The art is the province of the artist. TASCAM can make no guarantee that the 32 in itself will assure the quality of the recordings you make.
我们为 32 提供的性能保证必须有几个限制。我们说，只有调整得当，录音机才能正常工作，并且保证这种调整是可能的。但是，我们不能保证您的调整技能或您对本手册的技术理解。因此，基本日常设置不在保修范围内。如果您尝试对 rebias 和 record EQ trim 等进行内部调整未成功，我们必须收取服务费以纠正您的错误。录音是一门艺术，也是一门科学。成功的录音通常主要根据声音作为艺术的质量来评判，我们显然无法保证这一点。一家为艺术家制作油漆和画笔的公司不能说用他们的产品制作的画作会受到评论界的好评。艺术是艺术家的领域。TASCAM 无法保证 32 本身将保证您制作的录音质量。
Your skill as a technician and your abilities as an artist will be significant factors in the results you achieve.
您作为技术人员的技能和您作为艺术家的能力将是您取得结果的重要因素。

WARNING : TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
警告 ： 为防止火灾或电击危险，请勿将本设备暴露在雨中或潮湿环境中。
