HITEC Focus III FM - Manual (Page 6)

d. Transmitter Antenna
Always make sure your antenna is attached and fully extended before use otherwise
your operating range will be greatly reduced and could result in damage to your aircraft
and or injuries to yourself and others.
e. Changing Crystals
Changing crystal to avoid conflicts with other aircraft is possible where permitted. (You
must check your local rules before doing so. For example in the US the FCC prohibits
the changing of transmitter crystals on 72 and 27MHz). If you are allowed to change
crystals, both the transmitter and receiver crystals must be changed together. You must
change within the same band; i.e. 72MHz to 72MHz, 27MHz to 27MHz, different
bands can not be intermixed, if your radio is on 72MHz then 27MHz crystals cannot
be used. Use only Hitec crystals when changing frequencies.
