To adjust the control stick length, use a 2mm Allen
wrench to unlock the set screw located inside the
end of the control stick. Turn the set screw
counterclockwise to loosen it, then turn the knurled
portion of the stick to adjust the length.
Counterclockwise will lengthen the stick and
clockwise will shorten it. After the control stick(s)
has been adjusted to suit your flying style, tighten
the set screw back.
For proper DSC hook-up and operation:
1. Leave the transmitter power switch off. The
transmitter will not transmit any radio
frequency (RF) in this position.
2. Plug the optional DSC cord (JRPA132) into the
DSC port in the rear of the transmitter.
3. The encoder section of the transmitter will now
be operational and the LCD display will be lit.
4. Plug the other end of the DSC cord into the
receiver charge receptacle. Turn on the switch
harness.
Note:
When installing the optional charging jack
(JRPA024) 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 enables you to check the control
surfaces of your aircraft without drawing the
fully operational 200mAh from your transmitter
battery pack. Instead, you will only draw 70mAh
when using the DSC function.
Note:
You will need to purchase (separately) both
the DSC Cord (JRPA132) and the JR Deluxe Switch
Harness (JRPA001) to make use of the XP652 DSC
Function.
2. The DSC function allows you to make final
adjustments to your airplane or helicopter
without transmitting any radio signals.
Therefore, if another pilot is flying on your
frequency, you can still adjust your aircraft and
not interfere with the other aircraft.
Note:
Under no circumstances should you attempt
to fly your aircraft with the DSC cord plugged in! This
feature is for bench checking your aircraft only.
There is an eye hook on the front of the transmitter
for attaching an optional neck strap (JRPA023). The
eye hook is precisely positioned (see Section 1.1) so
that the transmitter will be perfectly balanced when
a neck strap is used.
