FUTABA 9CAP Instruction Manual page 4

MODULE: 72TP-FM
•
Module may be easily removed and a module on a different channel (or even band) reinserted to change the frequency
on which the 9C transmits.
•
Module transmits both FM (PPM) and PCM. No need for a second module.
•
All transmission circuitry is included in the module, so no retuning is needed when changing channels or even bands.
•
Frequency band is changed by inserting a module on the proper band, including for international or ground model use.
•
In North America it is against FCC regulation to change the crystal within the transmitter module to a different
channel. All such transmitter crystal changes must be performed by a certified radio technician. Failure to properly tune
a system to its new channel may result in decreased range and may also result in interference to other types of frequency
users on adjoining channels. Doing so also voids your AMA insurance.
•
The FSS synthesized module for the 9Z family of radios is NOT compatible with the 9C.
•
Radio system beeps and RF
•
Non-Futaba brand modules are not FCC certified for use with this radio and therefore are against FCC regulation to use.
Doing so also voids your AMA insurance.
•
TJ75FM modules may also be used with the 9C for ground use models such as robotics, rocketry, trains, cars, and boats.
RECEIVER: R138/R148/R149
•
The R138 or R148 FM 8-channel or the R149 PCM 9-channel receiver included with your system is a high-sensitivity
narrow-band dual-conversion receiver.
•
Note that your 9C transmitter is capable of transmission on both PPM (FM) and PCM with just a simple programming
change and just turning the transmitter off and back on. (See p. 28.)
•
Any Futaba narrow band FM receiver (all produced after 1991) on the correct frequency band and frequency may be
used with the 9C.
•
Any Futaba PCM 1024 receiver on the right frequency band and frequency may be used with the 9C (all 1024 receivers
say PCM1024; receivers which say PCM but not 1024 are 512 resolution and not compatible).
NEVER attempt to change a receiver's band by simply changing crystal (IE removing a 72MHz crystal and inserting
a 75MHz crystal). A receiver that has a crystal installed from a different frequency band without retuning will not
receive properly and will have dramatically decreased range.
•
In North America the receiver included with this system may have its frequency changed by simply changing the crystal
as long as it remains in the same half the band. A low band receiver between channels 11 and 35 may be changed to
any other channel between 11 and 35 without requiring any tuning. A high band receiver between channels 36 and 60
may similarly be changed. Receivers being changed from a high band channel to a low band or vice versa require proper
tuning and service by the Futaba Service Center.
SERVOS
• Please see technical specifications page for specifics on the servos included with your system.
• The included receiver is compatible with all J-plug Futaba servos, including retract, winch, and digital servos.
