Step 2 It is recommended that the Intercom be mounted to a Gooseneck post or non-metallic surface. NOTE: Metal surfaces can shorten the range of the Intercom. If mounting on a metal surface and long range is required, use a non-metallic spacer to move the Intercom away from the metal surface. The Intercom is waterproof so that rain or high humidity will not effect it. However, do not mount Intercom in the direct path of a sprinkler system as the Intercom’s life can be reduced.

THERE ARE NO OTHER USER SERVICEABLE PARTS. Tested to Comply with FCC Standards FOR HOME OR OFFICE USE. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FOR TECHNICAL SUPPORT DIAL OUR TOLL FREE NUMBER: 1-800-528-2806 www.liftmaster.com Troubleshooting When it gets cold, Intercom does not function. In this case, use AA Photo Lithium batteries, which are 1.5V each. They will also extend battery life. Intercom is not getting expected transmission range. Metal surfaces can shorten the range of the Intercom. If mounting on a metal surface and long range is required, use a non-metallic spacer to move the Intercom away from the metal surface. When used in buildings with stucco or cement walls, the range is greatly reduced. Repeaters can be used close to the building to solve this problem. Repeaters can also be used if there is a 900 Mhz noise source nearby that is affecting the range. When using with Repeaters, the sound is not clear. Ensure that the Repeaters are properly programmed. To test, remove the batteries from one Repeater. If the remaining Repeater is working, switch the batteries and test the other Repeater. If one of the Repeaters does not work, it means if has not been programmed. Both Repeaters must be programmed for the system to work. Intercom is too loud/not loud enough. Adjust Dipswitch #4 as explained in the Operation section. Intercom is too sensitive/not sensitive enough. Adjust Dipswitch #3 as explained in the Operation section.
