The YJ Pocket Timer has two infrared sensors located on each side of the timer. These detect when your hands are near the timer. This saves a lot of space, and as a result, a compact, flexible and stylish timer has been created. This timer is made specifically for speedcubing and will save your times so you can see your average of the last five or twelve solves as well as the average for your entire session. The instructions that come with the timer are only available in Chinese. We have translated them below.
How to use the YJ Pocket Timer
Lay down the timer on the table. Place your hands on each side of the timer. You will now see a red light, which means that the timer has detected your hands and is ready to start timing. When you raise your hands to pick up the cube, the timer starts counting. Once you have solved your cube, lay it down on the table and place your hands on each side of the timer again to stop the time. This is exactly the same method used in official competitions.
The switch on the left side of the timer: Start / Shut down. If you want to clear all your saved times, you can restart the timer with this switch to reset it.
Right button on the front side: Reset – clears the most recent time so you can start a new solve. Press and hold the button for two seconds to toggle the sound on or off.
Left button on the front side: To see your results – Press the button once: Shows the average of your 5 latest solves (3 out of 5). Press the button twice: Shows the average of your 12 most recent solves (10 of 12). Three times: Displays your total average for the last session (every solve since you started the timer).
