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.
