For proper DSC hook up and operation:
1. Leave the transmitter power switch in the OFF position. The
transmitter will not transmit any radio frequency (RF) in this
position.
2. Plug the DSC cord (optional) 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 the switch harness to the ON position.
Note: The DSC function will only operate with the JRPA001
Deluxe Switch Harness, or the JRPA004 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 enables you to check the control surfaces of your
airplanes without drawing the fully operational 200 mAh from
your transmitter battery pack. Instead, you will only draw 70
mAh when using the DSC function.
2. The DSC function allows you to make final adjustments to
your airplane without transmitting any radio signals. Therefore, if
another pilot is flying on your frequency, you can still adjust your
airplane and not interfere with the other pilot’s aircraft.
Note: Under no circumstances should you attempt to fly your
airplane with the DSC cord plugged in! This function is for
bench checking your airplane only.

An eyelet is provided on the face of the XP8103 transmitter
which allows you to connect a neck strap (JRPA023). This hook
has been positioned so that your transmitter has the best possible
balance when you use the neck strap.
Note: Double check to ensure that the neck strap is securely
fastened to the transmitter.

An optional base loaded antenna is available for use with the
XP8103 transmitter. It is considerably shorter than the standard
antenna. However, the base loaded antenna cannot be
collapsed for storage in the side of the transmitter. You must also
use an adaptor (JRPA156) to attach the antenna to your XP8103.
The base loaded antenna (JRPA155) is made of a flexible coil
and is covered with a soft plastic material. Your range will not
be affected when using the base loaded antenna.
