The Zomet Institute of Halacha and Technology, which specializes in adapting modern devices foruse within the scope of Jewish law, has developed a “kosher” walkie talkie – one that can be used on Shabbat, when Jews are generally forbidden to use electronic equipment.
The device was developed at the behest of the Chabad House in Hong Kong, in order to enhance security on Shabbat, but also in a way that conforms with Jewish law.
It should be noted that prohibitions against using communications equipment, such as walkie-talkies, are generally suspended on Shabbat because of the “danger to life” that could result from a lack of security, especially in public places like synagogues.
Goddamnit anons ! The enemy has researched tier 2 tech level walkie-talkies!
