Frequency/Channel Considerations

As with any radio device, interference can occur at any time. The frequencies offered are shared with other legitimate us- ers. Check the frequency/channel with a receiver to see if any interference is present. If interference is present, choose a different channel. The severity of interference varies with location and distance to the interfering station. If the interfer- ence is weak on all channels, this is probably acceptable since the PST-170 will cover the interference and is unlikely to interfere with other users. Multiple Channel Systems re- quire other considerations but each channel should be checked as above.
