Description

Compatibility: Liftmaster 61LM CONTENTS This remote is a very small (1/2″ x
1-7/8″ x 1-1/2″) key-chain style remote operating at 390 MHz. It achieves its
small size by using state-of-the-art components. It has been designed for use
with; LiftMaster dip-switch receivers. CODING Access to the remote’s toggle
code switch is achieved by unscrewing the back cover. Set the NINE-digit
toggle code switch to match the code set in the receiver. Move switches using
a small pointed object, such as a paper clip. Gently switch the small switches
to either +, -, or Neutral positions. When complete screw the back cover back
into position OPERATION Once the codes are set to match the transmitter codes,
you may test the system. Ensure the gate or door is visible and clear before
testing. Step 1- Push the remote’s button from a distance of about ten feet.
If the receiver activates, the switches are properly set. Step 2- Test the
transmitter from several locations to discover any “blind spots” caused by
interference. BATTERY ACCESS Unscrew the back cover to reach battery
compartment. Be aware of battery polarity when replacing the A23 battery.
