Setup
1. Battery Installation
The SPINTSO Referee Watch uses two CR2032 batteries. If the battery indicator shows low power or the watch is not functioning, replace the batteries as follows:
- Carefully open the battery compartment on the back of the watch using a small screwdriver.
- Remove the old batteries.
- Insert two new CR2032 batteries, ensuring correct polarity (+/-).
- Securely close the battery compartment.
2. Initial Time Setting
Upon first use or after battery replacement, you may need to set the current time and date. Refer to the "Operating" section for detailed instructions on navigating the watch's menus to set time, date, and other general settings like 12/24 hour display and summer time.
3. Game Program Settings
Before a game, you can program the watch with specific game parameters. This includes setting the number of periods, the duration of each match time, and break times. These settings are crucial for the watch's automated referee functions.
- Periods: Define the total number of game periods.
- Match Time: Set the duration for each playing period (e.g., 45 minutes).
- Break Time: Configure the duration of breaks between periods.
Detailed instructions for programming these settings are provided in the "Operating" section under "Referee Mode Settings."
