XP70 Instruction Manual
1. Leave the transmitter power switch in the OFF position.
The transmitter will not transmit radio frequency (RF) in
this position.
. Plug the DSC cord (optional JRPA1) into the DSC
port in the rear of the transmitter.
. The encoder section of the transmitter will now be
operational and the LCD display will be lit.
. Plug the other end of the DSC cord into the receiver
charge receptacle. Turn the switch harness to the ON
position.
NOTE
: The DSC function will only operate with the
JRPA001 Deluxe Switch Harness, or the JRPA00
Charge Switch. When you install the charging jack,
be sure to hook the charging jack receptacle securely
into the switch harness charge cord.
Why you should use the DSC function:
1. The DSC function allows you to make adjustments
to your model without transmitting any radio signals.
Therefore, if another pilot is flying on the same
frequency, you can adjust your model’s radio setting
and not interfere with the other pilot’s aircraft.

of your airplanes without drawing the fully operational

fly your airplane with the DSC cord plugged in.
