Ensure intercom is connected to a network. See Programming Intercom. Ensure that intercoms are on the same channel. See Operation & Features. Intercom is not getting expected transmission range. Keep antenna vertical. Keep intercom away from metal objects and electrical wiring. Cell phones, cordless phones, or other radio devices may also limit range. Intercom beeps every ten minutes. The battery is low in the intercom. Replace with AA Alkaline batteries or operate it with AC Adapter (not provided). A 12 volt, 300mA AC Adapter may be used

(center positive polarity on the round plug). Static and feedback is heard in intercom. The intercoms are too close to each other. A cordless phone, cell phone, or other radio devices can also cause static. Need to clear intercoms memory. Press and hold Learn button, an initial beep will be heard. Continue to hold until a second beep is heard

(about 15 seconds). Ensure other intercoms are not activated during this time. Intercoms in the network that are on will signal during the clearing process. Once memory is clear the intercom can be programmed to a new network. Intercom is sending audio while no buttons are pressed. The sending intercom is set to Monitoring Mode or Voice Activation Mode and will activate when sound is heard. It can be taken out of Monitoring Mode by pressing the Talk button. It can be taken out of Voice Activation Mode by setting Dipswitch #1 to DOWN position. See Operation & Features.
