ABOUT DUAL FREQUENCY
REMOTE TRANSMITTERS
Your garage door opener (GDO) features a
unique dual frequency remote control system
for reliable service in today's 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 Figures
13A and 13B for frequency selector switch.
Switch your remote control frequency when:
• Remote does not have adequate range.
• Remote works inconsistently with fresh
battery installed - LED feedback lights up
when pressing button.
• Programming your car's HomeLink® system.
To program a HomeLink® device:
(This GDO is HomeLink® compatible.)
• Use a small flat screwdriver to switch the
frequency selector to 390 MHz.
• Follow the HomeLink® instructions in your
car owner's manual.
• Reset the remote control frequency to
315 MHz for everyday use.
Settings Step 7:
