Your intercoms have four channels to set the radio frequencies used to communicate with each other. They also have eight sub tone settings to help eliminate interference. Your intercoms must be set to the same channel and sub tone for them to communicate with each other.1. Set each intercom to channel 1, 2, 3, or 4 as shown. 2. Set each intercom to sub tone 1–8 as shown.n Note:• If you want all the intercoms to communicate with each other, set them to the same channel and sub tone.Thank you for purchasing your Voice-Activated Wireless Intercoms from RadioShack.

Do not burn or bury them.• Use only fresh batteries of the required size and type.• Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.• If you do not plan to use the intercoms for a long time, remove the batteries. Batteries can leak chemicals that can damage electronic parts.• If you want one intercom to communicate only with one other intercom, set only those two intercoms to the same channel and sub tone.• If you receive occasional interference falsely triggering your intercom, you can set each intercom to a different sub tone. However, if there is frequent interference that affects the conversation or audio quality, set your intercoms to a different channel.3 Use Your IntercomsTo turn on an intercom, rotate VOLUMEtothemaximumvolumedirectionuntilitclicks.ThenadjustVOLUME to a comfortable listening level.
