E-Collar Technologies - Transmitter EZ-903/904 2T - Replacement Remote

Looking to turn your existing system into a 2T system (two remotes on the same frequency) or need to replace a lost remote? Instead of replacing the entire system, just program it with a new replacement part. 2T Systems are great for: -Large properties where one remote might be kept in an out-building while the other remains in the house. -One for yourself, one for your partner. -Extra in case of misplaced or lost. Note: 2T transmitters are manufactured on the same frequency and must be purchased as such to work together. You cannot program a single transmitter to create a 2T transmitter set.
