( System is new or the Repeater was not used in the system previously)

• If the Repeaters are not new, or have been PAIRED to a system before, YOU MUST CLEAR THE REPEATER MEMORY:

  • Hold the button on the Repeater PCB until the LED stops Blinking. (About 20 seconds) see step 5

• To teach the Repeater, first put the GAP in Learn Mode  (enter the master PIN, then 05, and after it beeps, press the CALL button), then press the LEARN buttons on the repeater modules for one second, one after the other (not at the same time).
• Now teach the accessory to the Repeater (typically, an Intercom or Telephone Interface); Place the Intercom in Learn Mode (press the LEARN button or dial **07 on the OTIU’s phone), then hold down the LEARN button on one of the Repeater modules for one second.
• Repeat for each Intercom or OTIU in the residence.
• MAKE SURE YOU HAVE PLACED ONE OF THE Repeater's DIP SWITCH #1 TO ON. The other Repeater switch #1 should be OFF.

( System was already established and the GAP had been PAIRED to an Intercom or Telephone Interface.)

• If the Repeaters are not new, or have been PAIRED to a system before, YOU MUST CLEAR THE REPEATER MEMORY:

  • Hold the button on the Repeater PCB until the LED stops Blinking. (About 20 seconds)

• You must Clear The Memory Of All Intercoms and OTIU Telephone Interface, before proceeding to the next step. No need to clear the GAPLM memory.
• To teach the Repeater, first put the GAPLM in Learn Mode  (enter the master PIN, then 05, and after it beeps, press the CALL button), then hold down the LEARN buttons on the repeater modules for one second, one after the other (not at the same time).
• Now teach the accessory to the Repeater (typically, an Intercom or Telephone Interface); Place the Intercom in Learn Mode (press the LEARN button or dial **07 on the OTIU’s phone), then hold down the LEARN button on one of the Repeater modules for one second.
• Repeat for each Intercom or OTIU in the residence.
• MAKE SURE YOU HAVE PLACED ONE OF THE Repeater's DIP SWITCH #1 TO ON. The other Repeater switch #1 should be OFF.

• To test the Repeaters, first perform the TEACH steps. Then,
  1. Remove the batteries from BOTH Repeater Modules.
  2. Press the CALL button on the GAPLM.
  3. If the system does not connect, go to Step 5
  4. If the system connects (The intercom or Telephone Interface (OTIU) Ring, then you have not properly performed the Teach Steps involved with the Repeaters. Repeat Step 3.
  5. If you have reached this step, the system is not functioning at all with batteries of the Repeaters removed. Now:
     1. Install the batteries of ONE OF THE REPEATERS.
     2. Press the CALL button. The system should function.
     3. Remove the batteries from the first Repeater that you just tested and insert them into the 2nd Repeater. Press CALL again. The system should work.
     4. Insert batteries in BOTH Repeaters. System should work.
• MAKE SURE YOU HAVE PLACED ONE OF THE Repeater's DIP SWITCH #1 TO ON. The other Repeater switch #1 should be OFF.

• Very Long Range... see step 7
• The range is less than 100 to 200 feet and yet you cannot get a good connection... see step 8

• If the GAPLM (Or Door Access Intercom, Front Door, etc) is located very far away, you will need a Repeater to establish a robust connection.
• The Line Of Sight Rating of the LiftMaster products is about 1000 feet. The range is reduced when there are blockages, such as Stucco, Trees, Hills, etc.
• Range is reduced if there are sources of 900 MHZ Radio Interference, such as Wireless Video Monitors.
• For long range use, PLACE THE REPEATERS ABOUT HALF WAY between the communicating devices.
• Mount higher than 4 feet from ground.
• Mount the Repeater Modules in a place that has the best chance of a clear signal between communicating devices.
• Both Modules of the Repeater set should be mounted to be at the same distance from the GAPLM.. however,
• Keep the modules apart by no less than 10 feet and no more than 30 feet from each other.

Using with Stucco Homes

• Even when the range is reasonably short, you could still experience a poor connection.
• This is due to either a noise source matching the system frequency set at 900 MHZ, of due to a blockage that does not allow the radio to penetrate (Such as stucco)
• Before installing repeaters:
  • Try changing the SYSTEM CHANNEL SET... Enter PIN#, 55, then 2 or 3 (The system is shipped with the default frequency set of 1. You can change the frequency set to 2 or 3). Once you have performed this step, you much re-teach the intercoms and OTIU to the GAP again. Did this solve the issue?
  •  If the above step did not help, change the location of the Intercom or OTIU. Is there a COMPUTER PRESENT NEARBY? Try turning it off. Is there another source of noise, such as a 900 MHZ Video Device? Turn it off and try the system.
• If the above step was not helpful, install the repeater:
  • In the case that the system range is shorter than a few hundred feet without Repeaters, you must place the Repeaters NEAR THE HOME... (NOT half way from the GAPLM).
  • You can mount the Repeaters on a roof truss, or, mount within 50 feet of the home on posts.

• Repeaters can be cascaded.
• To Cascade, you must Teach in this order:
  1. Teach GAPLM to Repeaters
  2. Teach ONE of the Repeaters to each of the repeater modules of the 2nd set.
  3. Teach ONE of the 2nd set of the Repeaters to the Intercoms and OTIU.
