Notes in regard to using 72MHz and 216MHz systems

i.72MHz in a secondary frequency band. This means that other transmitters are licensed to use these frequencies. Thus, you may experience interference from paging transmitters and other type transmissions. You will need to find a clear channel by listening to all the wide band channels.

ii.216MHz is a primary frequency band and no other types of transmissions are authorized to use it. Thus, you will find the highest probability of clear channels in this band. However, you may experience intermodulation of the TV Channel 13 aural carrier if there is a channel 13 trans- mitter in your area and you are close to the transmitter. If you cannot find a clear channel in 216MHz band due to channel 13, it is recommended that you switch to a 72MHz system.

NOTE: The LR-300-072 can only be used with the 17 wide band 72MHz channels, if you are using the LR-300 choose only lettered wide band frequencies on your transmitter.
