How do I configure the LEAP PQ9907S Digital Chess Clock for different game modes?

[StErin]

Setting up the LEAP PQ9907S Digital Chess Clock involves a few straightforward steps, depending on the game timing you need.

For positive timing:

1. Power on the clock by inserting a battery and setting the "ON/OFF" switch to "ON".
2. The display will show "0:00 00".
3. Use the rocker switch to designate which side starts first.
4. Press "" briefly to begin the clock.

To set countdown timing (same time for both players):

1. From the positive timing screen, press and hold " < + > " for two seconds to enter the countdown setting mode.
2. The hour digit on the left will flash.
3. Use " < + > " or " < - > " to adjust the time, in increments of one, to your desired value.
4. Press "" briefly to move to the minutes and then seconds.
5. The time set on the left side is automatically copied to the right side initially.
6. After setting the time for the right side, you can set the increment (bonus) and delay. The factory settings for both bonus and delay are 0.
7. Press and hold "" for two seconds to exit the setting mode.
8. Start the clock.

To set countdown timing (different times for each player):

1. Follow the same steps as above for countdown timing, but modify the time on the right side to reflect the different time each player will have.
2. Start the clock.

Note: Only one mode (bonus or delay) can be used during a game. If the bonus time is greater than 0, the delay period will be 0, and vice versa. For detailed information, consult the LEAP PQ9907S Digital Chess Clock Instruction Manual.
