ABOUT DUAL FREQUENCY

REMOTETRANSMITTERS

Your garage door opener (GDO) features a unique dual fre- quency 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 Figure 2 and 3 on page 11 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.
