An apparatus for the activation of a remote device having a transmitter to generate and transmit user-set special coded signals. The transmitter has a function selector switch to select modes of operation for the transmitter. Included is also a receiver to receive the user-set special coded signals, and the receiver also has a function selector switch to select modes of operation for the receiver. The function selector switch selects the following modes of operation for the transmitter: (a) a &ldquo;transmit/fire&rdquo; mode that enables a fire signal to be transmitted to the receiver; (b) a &ldquo;wake-up&rdquo; mode that enables a set-up receiver mode for immediate firing; (c) a program mode for low power transmission of programmed codes; and (d) a &ldquo;test&rdquo; and operational mode that enables an operational test of the apparatus with no firing output. The function selector switch on the receiver selects the following modes of operation for the receiver: (a) receive a &ldquo;wake-up&rdquo; of &ldquo;fire&rdquo; signal; (b) actuate either an electrical excitation output or an electromechanical solenoid output; (c) provide a continuity test for a blasting cap; (d) program the receiver for receiving programmed codes; and (e) conduct operational tests of the receiver.
