The JZD020-013 portable basketball timer and scorer manual explains setup, operation, and maintenance for tournament use.
This manual describes the portable basketball timer and three‑digit decimal scorer packaged in three aluminum cases. It outlines the purpose, features, and the components included: the timer, two scorers, control cables, power cables, and a data control box.
Step‑by‑step instructions cover opening the cases, arranging the displays, connecting cables safely, powering the unit, setting the 20:00 countdown, adjusting the timer, and operating the scorer. It also provides guidance for handling short power outages, resetting the clock, and proper storage to avoid water damage. This manual is written in Chinese.
| Countdown timer range | 20:00 (20 minutes) |
|---|---|
| Score display format | Three‑digit decimal |
| Power supply voltage | 220 V AC |
Press the “20:00” key and the clock will reset to twenty minutes zero seconds.
When power returns, the scorer keeps its previous value, but you must reset the clock to the time before the outage.
Do not connect the 220 V power while attaching cables; ensure correct orientation and hook the safety latch on the socket.
