The MTE is a hand-held, battery powered keypad used by the judges to enter scores given to the athletes during aquatic sports such as diving, synchronised diving and synchronized swimming.

A twelve hour battery life without recharging and wireless connectivity makes poolside setup very fast and simple.

The 128 x 64 pixel Display (LCD) is able to display up to eight lines of twentyone characters and also has graphic capabilities, facilitating useful feedback to the judges.The MTE is fitted with an orientable antenna for wireless data transmission, providing up to 100 metres of range in open space, or can be used as a wired device whenever wireless functionallity is compromised. All MTE units are linked to a centralised scoring system using the industry standard ZigBee transmission protocol. The multi use connector also acts as input for external power and recharge purposes.

In addition to the numeric keypad, The MTE features seven additional function keys all protected (IP64) by an embossed splashproof sheet allowing them to be used close to poolside.
