Please note that there is an error in both the Simplified and Traditional Chinese Versions of the Advanced Open Water Diver Course Student Manual, in the Deep Dive section on Page 77 – Version #70139SC and #70139C.
The translated, printed versions state incorrectly that if you have to ascend following a computer failure you should “make a three-minute (or longer) safety stop at 18 metres/60 feet”. The correct depth for this stop is 5 metres/15 feet.
Here is the correction for the printed student manual in Simplified Chinese:
在水深 5 米／15 英尺处（或电脑表说明书指示的深度）做 3 分钟（或更久）的安全停留。
Here is the correction for the printed student manual in Traditional Chinese:
在水深 5 公尺／15 英呎處（或電腦錶說明書指 示的深度）做 3 分鐘（或更久）的安全停留。
Please take note of this for your Chinese-speaking student divers. The manual will be corrected upon reprint.
