Equipment Set-up
For set-up instructions specific to the Discover Free Fall System or
Shoot-the-Target Accessory, refer to the manuals included with those
systems.
1. Connect the included AC Adapter to the POWER jack on
the control box.
2. Connect a photogate or timer switch to the PHOTO-
GATE port on the control box. (You can skip this step if
you plan to use only the PUSH TO DROP button on the
drop box.)
3. Use the included cable to connect the SIGNAL TO
DROP BOX jack on the control box to the TO CON-
TROL BOX jack on the drop box.
4. Mount the drop box on a horizontal support rod (see Fig-
ure 1), or remove the thumbscrew and attach the drop box
magnetically to a steel part of the ceiling (see Figure 2).

5. Stick a ball (from the ME-9889 Discover Free Fall Sys-
tem), target (from the ME-6853 Accessory), or similar
object to the magnet on the underside of the drop box.
6. To make the object drop, block the photogate or push the
timer switch or press the PUSH TO DROP button on the
drop box.
Note the READY LIGHT on the drop box. After the drop
box is triggered, the light blinks for a few seconds to indicate
that the drop box is recharging. Wait until the light glows
steadily before triggering the drop box again.
It you are using a photogate, you may want to disable it to pre-
vent unwanted triggering. Set the ACTIVE/INACTIVE
switch on the control box to INACTIVE to disable the trigger.
