Disable Error Checking (switch 7)
– The JrX Receiver performs error checking on all radio messages. This ensures
that background radio signals do not cause the JrX to false trigger. In nearly all situations error checking should remain
enabled (switch 7 is OFF or “0”) which is the default setting. There are two situations where it may be desirable to
disable error checking (switch 7 on ON or “1”).
Operation at the edge of radio range: The radio signal is a stream of digital 1’s and 0’s. Near the edge of range,
there may be some errors in the incoming radio transmission. It is likely that enough of the signal has been received
correctly for the JrX to operate, yet a single bit error would cause error checking to disregard the message. By disabling
error checking, the receiver may still activate even if the signal has some bit errors.
Operation with certain Canon bodies and certain lights at 1/250 shutter speed: RadioPopper has observed that a small
number of Canon camera bodies when triggering a small number of studio strobes at the max x-sync of 1/250 can
produce shots with a very faint, almost unnoticeable shadow from the camera shutter on the bottom of the frame. By
disabling error checking, the remote light will activate more quickly and this effect will be eliminated.
Note that a negative effect of disabling error checking is that the JrX Receiver may occasionally false trigger due to
background radio noise. As false triggering is a “negative” effect, error checking should always be enabled except in
the two circumstances indicated.
Modeling Lamp Tracking (switch 8)
– The the JrX Receiver is attached to an Alien Bees, White Lightning or Zeus
strobe using the EZset function, a user may or may not want the strobe’s modeling lamp to track with the power
adjustment. The default position of switch 8 is ON or “1” in which modeling lamp tracking is enabled. Changing to the
OFF or “0” position will turn off tracking. NOTE: When turning off tracking is desired, you must also turn off tracking on
the strobe control panel. You may observe that the modeling lamp still slightly changes with tracking disabled which
is normal and is an effect due to electrical coupling inside the controlled light.
IMPORTANT NOTE: If Modeling Lamp Tracking is desired, switch 8 must be turned ON. Additionally, you must set (turn
“on”) the model lamp tracking button on the rear controls on the light itself.
Battery Level Check / Alarm
Both the JrX Transmitter and Receiver units include a battery level indicator and low battery level alarm. The supplied
battery should provide 40-50 hours of continual “on” time regardless of the number of shots taken. When the JrX units
are turned on, or when the power button is tapped one time, the unit will indicate the battery level by strobing the
green power light. The power light will strobe fast for full battery, half speed for mid-battery and very slowly for a
low-battery. Approximately 2 hours before batteries are completely dead, the power light will begin to blink slowly.
During this blinking the units will still operate normally at full speed and full power with no noticeable loss of range,
however, it is recommended to replace the battery as soon as possible.
