INSTALLATION AND REMOVAL OF THE TRANSMITTER BATTERY The T8J transmitter is designed to work with either four (4) AA alkaline dry cell batteries, or HT5F1700B/ FT2F2100B battery pack, both available separately. The transmitter batteries used are a matter of personal preference. AA Alkaline batteries are available at any local hobby shop, grocery store, etc. A battery pack will need to be purchased from a hobby shop.

RADIO INSTALLATION Follow these guidelines to properly mount the servos, receiver and battery. $ Z alignment tab on the battery, switch and servo connectors is oriented correctly and “keys” into the corresponding notch in the receiver or connectors before plugging them in. When unplugging connectors, never pull on the wires. Always pull on the plastic connector instead.

LINK PROCEDURE (T8J transmitter/R2008SB): Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and no further linking is necessary unless the receiver is to be used with another transmitter. When you purchase additional R2008SB receivers, this procedure is necessary; otherwise the receiver will not work. 1.
S.BUS INSTALLATION This set uses the S.BUS system. The wiring is as simplified and clean mounting as possible, even with models that use a large number of servos. In addition, the wings can be quickly installed to the fuselage without any erroneous wiring by the use of only one simple wire, even when there are a large number of servos used.

WARNING & ERROR DISPLAYS An alarm or error indication may appear on the display of your transmitter for a number of reasons, including when the transmitter power switch is turned on, when the battery voltage is low, and several others. Each display has a unique sound associated with it, as described below. LOW BATTERY ERROR: Warning sound: Continuous beep until transmitter is powered off. The LOW BATTERY warning is displayed when the transmitter battery voltage drops below 4.1V. (5CELL mode 4.

A LOOK AT THE RADIO'S FUNCTIONS STEP BY STEP MODEL SELECT submenu: includes three functions that manage model memory: MODEL SELECT, MODEL COPY and MODEL RESET. Since these functions are all related, and are all basic features used with most models, they are together in the MODEL SELECT submenu. MODEL SELECT: This function selects which of the 20 model memories in the § are indicated after its number.
GOAL of EXAMPLE: Copy model 3 into model 5. STEPS: INPUTS: Open the menu, then open MODEL for 1 second. SELECT submenu. if required to MODEL SELECT. NOTE: This is one of several functions for which the radio requires Confirm you are currently using the If SELECT does not indicate 3, use MODEL proper model memory. (Ex: 3) SELECT, p. 27.
