The Retekess TM101 is a wireless game answer buzzer and countdown timer designed for quiz competitions, parties, classrooms, and other interactive events. It is easy to operate and adds fun and excitement to every game.
Using 2.4 GHz wireless technology, the TM101 provides stable long-distance transmission without the limitations of wired connections.
The working range can reach up to 80 m (262 ft) in open areas.
Mode 1: No 3-second countdown, no foul detection, and only the first successful button lights up green.
Mode 2: Includes a 3-second countdown, a timer from 0 to 999 seconds, and foul detection. Players who press the buzzer during the 3-second countdown are considered to have committed a foul and will be indicated by a red light. The game must then be restarted.
Mode 3: Unlike Mode 2, if a player presses the button during the 3-second countdown, the game does not need to be restarted. At the end of the round, the first successful player is shown in green, the fouling player is shown in red, and the losing players remain unlit.
1. The screen displays the button number of a successful answer or a foul. For example, if Button No. 2 commits a foul, the screen will display “No. 2 foul.”
2. The standard set includes one display, one remote control, and four buzzer buttons.
3. Each set supports up to 32 button groups. You can contact us to purchase additional buzzer buttons.
4. Each buzzer button is battery-powered and has a power switch. If no command is received within 30 minutes, the button will enter sleep mode to save power.
5. Different indicator colors represent different results: green for the winner, red for a foul, and no light for losing players.

Ideal for school competitions, party games, knowledge contests, and classroom Q&A sessions.
