Several friends mentioned to me that after receiving Brinyte A02, the battery indicator showed green (fully charged), but A02 could not be turned on. They asked me whether it was broken…T^T…
In fact, the high probability is not. This is because the A02 has a locking function. The A02 was sent to the buyer in a locked condition because of concerns that it would light up during shipping. The buyer can check the manual after receiving it, and unlock it according to the corresponding steps!You need to Click the A02 switch three times in quick succession to unlock the A02. If you just press A02 very slowly, three times at long intervals, it won’t unlock either! Please don’t think it’s broken directly.>^<
The secret is to be fast! Continuous! The interval is very short! Click three!
