OPERATION:   The11-67 is operated by pressing one of the four buttons on the front panel. Each button must be
held down for half a second before transmission commences to allow for accidental presses. Transmission is
indicated by the TX LED illuminating.
If transmission retries have been selected, the unit will go into a wait period between transmissions indicated by the
TX LED flashing faintly. Cessation of transmissions is indicated by the TX LED going off completely.
