When combined, the WR-R10 and WR-T10, uses radio frequencies to communicate by pairing a WR-T10 and one or more WR-R10 units. The WR-T10 used with cameras with WR-R10 unit attached, simultaneously release the shutter on multiple cameras. Unlimited number of cameras can be controlled by the WR-R10 when paired with the WR-R10 unit.
