Modulation: Means of transmitting data. See PMD, also PPM, PCM.
Module: Electronic device which can easily be removed/replaced into the transmitter,
which houses all Rf transmission components. Transmission frequency can be safely,
legally and easily changed (including from band to band) by changing the module. TK-
FSS is the synthesized module which allows the 9Z to transmit on any 72 MHz
frequency. TK-FM is the standard module, available on any 50MHz or 72MHz
frequency. Can be converted to 75MHz frequency for ground use by service team.
MSL:Model selection. Used to choose the model you desire to use. Q B F.
Momentary on switch: see ALT
Name: See MNA for model name, CNA for condition name, UNA for user name.
NOR: Normal. Normal trim adjustment, which affects the servo across its entire travel,
not only one half or the other. See ATL and TRM.
NUL: Null. Not assigned or never changed. For example, a mix which has a null switch
assignment is always active no matter what switch is moved.
NXT: Next. Continue to next screen within a feature.
OFS: Offset. Offset PMix Type. See PMX. Also see P. 2-8, P. 2-19.

Pitch to rudder. Heli programming only. This preprogrammed mix, also
known as a revolution mix or a tail rotor mix, counters the torque caused by
adding pitch with opposite direction rudder command to keep the helicopter
from rotating or revolving as a result of the increased torque. Not required
with the use of a heading-hold gyro, which self-counters the torque-caused
movement. Manual P.112.
PAR: Parameter submenu. Sets auto-off timer and screen contrast. Manual P. 33. Q C G.
PA2: Pilot Assist. Optional onboard device which uses optical sensors to correct model’s
orientation to upright.
Pitch Curve: See PCV for pitch curve adjustment; PIT for pitch curve attachment to
throttle.
Pitch for Hover: See PHV.
Pitch-to-rudder: See P R.
Pitch Trim: See PTM.
PCM: Pulse Code Modulation. An electronically encoded method of transmitting data to
a receiver to help minimize the effects of interference. Analog signals are encoded into a
stream of digits, coded as a series of pulses for transmission to the receiver. The greater
number of samples in the digital signal (i.e. 1024 vs. 512), the greater the resolution and
control precision. An increased signal-to-noise ratio allows PCM systems to exibit
minimal effects from interference. See PMD.
