ABOUT DUAL FREQUENCY
REMOTE TRANSMITTERS

crowded airwaves.Overcrowded airwaves may intermittently
interfere with GDO’s remote control system. The dual
frequency feature greatly reduces the possibility of
unwanted interference.
The receiver in the GDO’s powerhead can receive signals at 315
AND 390 MHz.The remote is factory set at 315 MHz. See Figure
2 and 3 on page 11 f
