About student remoteThe RF218 handset is designed for easy use with questions that require a numeric answer between 0 - 100 (e.g. 7 X 7 = Y), multiple choice questions (A, B, C, D, E, and F answer options), true/false questions, and yes/no questions. The handset has an LCD screen and answer transmission indicator that tells the students when an answer has been sent, and an answer confirmation indicator that tells the students their answer has been received by the system. This handset works with self-paced tests, group tests and quizzes, and for recording and submitting homework. In the self-paced mode, students have a paper copy of the test and work through the questions at their own pace. Students can go back and review questions and change their answers. In the group test mode, the questions are asked one at a time, either with a projector or verbally by the instructor. The group answers question one before proceeding to question two. The instructor controls the time allowed for each question. In the homework mode, students save the answers to the homework on the handset. During the next class, the students transmit the answers from their handset to the teacher’s computer. Handsets are interchangeable among students. If a student forgets her or his handset in another classroom, a spare handset can be quickly reset to the number assigned to that student. 2.4GHz digital RF technology LCD display 4 radios channels 11 Activity modules Support Self-Paced-Response Support Multi-Correct-Options ID Address Programmable Power required:two 1.5 volt batteries (alkalescent battery will be better) Transmission distance: > 100 meters Transmission angle: 360 degree Battery life: > 1 to 2 years for ordinary use Durable and not easily breakable, will not break or damage even drop to the cement ground from 5 meters high Easy to use Up to 999 remote controllers can be used at once (enhanced version) WDT reset support automatic program reset feature
