 changed
 within
 their
 own
 band.

 are
 2
 different
 bands
 for
you to choose  from (27 MHz and 75 MHz.)  Please see chart listed  below for specific  frequency and its intended use.
Please note there are specific frequencies allocated for aircraft only and surface only use.
•The

 within
 the
 same
 BAND
 by
 using
 a
 precisely
 matched
 pair
 of
 Futaba crystals.
 However,
Futaba recommends that you return your system to our  factory service department for frequency changing, as tuning
may be necessary for proper operation. Changing frequency  from one band to another is NOT  possible.
• Always  change  frequency flag when frequency is changed. The frequency flag is to be attached to the top of antenna
and the channel designation to the base. (See Drawing)
