selection chart on page 22) as long as the adjacent channel transmitter is at least 50% further away from an LR-100 than its own transmitter. Example: The transmitter for the LR-100 on channel E is 100 feet from the LR-100. The adjacent channel transmit- ter on channel D should be at least 150 feet away.

Notes in regard to using 72MHz and 216MHz systems:

i.72MHz is a secondary frequency band. This means that other applications such as paging systems are licensed to use these frequencies. Thus, you may experience inter- ference from other types of 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 autho- rized to use it. Thus, you will find the highest probability of clear channels in this band. However, if there is a TV Channel 13 in your area, you may experience intermodulation of the TV Channel 13 aural carrier. If you cannot find a clear channel in 216MHz band due to channel 13 interference, it is recommended that you switch to a 72MHz system.

NOTE: Once you have selected your transmit and receive channels, it is recommended that you lock the channel so that it cannot be changed by the user. To accomplish LOCK, press and hold the SEEK button for five seconds. Repeat to unlock.
