PCM9XII he JR PCM9XII uses the latest Computer and Display Screen technology to enhance and extend the Radio Control user's modelling experience. New to the PCM9X range is the Scroll Bar interface. In conjunction with the side entry buttons, the new Scroll Bar provides a quick, convenient and efficient programming environment.
MENU SYSTEM The PCM9XII Transmitter settings and functions are controlled from within two major menu systems: SYSTEM MENU LIST - The menu contains settings such as wing type, switch assignment etc., relating to the model type. Some sections of the Function Menu only appear when their corresponding section is activated in the System Menu List.
These switch harnesses include the orange signal wire, as well as the brown and red power wires. BACKUP The PCM9XII no longer utilises a Lithium Battery for backup. Model settings are now stored on Flash Memory that is believed to have an unlimited life.
FUSE The PCM9XII has a 3 amp internal fuse to protect the system in the event of a certain fault conditions. To replace the fuse, remove the RF Module, NiCad battery and back cover screws (six screws). Remove the transmitter back, being careful not to bend or damage the RF Module pins.
The Model Selection screen appears. Model Memories can be accessed and copied. The PCM9XII has 30 Model Memories and any Model Memory can store details of any model type. The Copy function allows the contents of the current Model Memory to be copied into another Model Memory and should not be confused with the "TRANSFER"...
