• Factory setting of transmitter modulation system
The transmitter modulation system (PCM/PPM mode) is switched by
data setting. (For the setting method, see P19.). However, it is set as
follows at the factory:

Refer to only the necessary items of the items enclosed in
*Use the special Futaba charger.
• The charging time is 15 hours.
[However when the battery was not used for some time, charge and discharge it 2 — 3 times. Otherwise, the battery will not be charged even after the specified charging time !
A fully-charged transmitter battery can be used for about 10 flights of 10 minutes each. The airborne NR4J Nicd battery pack can be used for about 6 flights when 6 servos are used.
Notes: (PBC-8B)
1)First, connect to TX Nicad and red lamp goes on.
2)Then, connect to RX Nicad after connecting, L, E, D, changes color from red to greenish red (orange) which indicates that both TX and RX Nicads are being charged.
3)In case of separate charging, L, E, D, color will be:
RX Nicad - Green TX NicadRed

*Load the battery while paying careful attention to the direction of the contacts.
2 Change the RF module.
Push in the new module, while being careful not to bend the pins, until the tabs at both sides lock into place with a "click".
*Use the special FP-TP-FM RF module for the FP7UAP and 7UAF. Other RF modules cannot be used.
•When the transmitter frequency band is changed, the receiver frequency band must be changed also.

PRECAUTIONS
•Connect the receiver, servos, switches, and battery as shown in the figure. Extend the trans-
mitter and receiver antennas to their full length.
•Turn on the transmitter power switch, then turn on the receiver power switch.
The servos will go to their neutral position. Move the transmitter sticks one at a time to check that each servo follows its control stick movement.
•Connect the pushrods to the servos and check that the direction of travel of each servo matches the direction of movement of its control stick. If a servo does not move in the proper direction, switch its direction with the servo reversing function.
•Operate each servo horn over its full stroke and check that the pushrod does not bind or is not too loose. Unreasonable force applied to the servo horn will adversely affect the servo and
- 4 -
• BEFORE USING
drain the battery pack very quickly. Make the travel of each control mechanism somewhat larger than the full stroke (including trim) of the servo horn. Adjust the servo horns so that they move smoothly even when the trim lever and stick are operated simultaneously in the same direction.
• Be alert for noise.
This set is noise-resistant, but not completely immune to noise. The use of noiseless parts is recommended.
•When installing the switch harness, cut a rectangular hole slightly larger than the full stroke of the switch and install the switch so that it moves smoothly from ON to OFF. Also do this when the switch is installed inside the fuselage and is turned on and off from the outside with a piece of wire. Install the switch where it will not be exposed to engine oil or dust and dirt.
•Although the antenna appears to be too long, do not cut it or fold it back.
•Install the servos securely. Tighten the mounting screws until the rubber damper is crushed slightly. If the screws are too tight, the cushioning effect will be adversely effected.

•The crystal can be changed from the outside of the receiver case. Always use the Futaba trans-
mitter/receiver matched crystal set to change the band.
•The receiver that is used with the 7UAP and 7UAF is a dual conversion receiver. This receivers requires a special crystal so please order the correct crystal set.
•Spare servo horns are supplied. Use them as needed.
•Use extension cords matched to the model.
•Wrap the receiver in sponge rubber. Place it inside a waterproof plastic bag and secure the end of the bag with a rubber band. Do the same with the airborne battery pack.
•Use the rubber bands wrapped around the receiver to hold the servo and switch leads.
•After installation and checking are complete, perform a range check by collapsing the transmitter antenna and extending the receiver antenna to its full length and operating the transmitter from a distance of 20 to 30 meters from the receiver. The servos should operate normally at this distance.
•Differs with the weather and surroundings.
