ZAP JR. MODULE
The Zap Jr. Module includes three components named Operation Game®, Role Playing Spaces, and Basic Anatomy Area. The later two components are essentially areas with several items. Each of the three components is discussed in the following detailed sections.
COMPONENT NAME – OPERATION GAME
Description
An oversized version of Hasbro’s Operation® Game. Visitors/children can actually climb on this low game table to perform simulated surgery. As with the original game, metal tongs (tethered) are used to extract or place the game pieces (bones, organs, etc.) into the appropriate pockets. If the visitor touches the side of the pocket with the tong, a buzzer sounds and the nose of the "patient" lights up.
Primary Components
The primary operational components include:
Two Zap Junior area signs (with integral benches and storage chests) delineate/support the general area.
Table 1 details the primary and associated components for this exhibit.Consumables / Spare Parts
The game tongs are sometimes inadvertently broken when pulled apart simultaneously by multiple visitors. Also, a game piece or the "O"-ring may be taken or lost. Table 2 lists available spare parts.
Special Instructions
The exhibit must be visually checked frequently for broken tongs or missing game parts. Be sure to check under the table for missing game pieces.
General Maintenance
Maintenance steps are simple and deal only with exhibit cleaning. See Table 3 for specific maintenance steps and frequency. Also, use Table 3 to document that maintenance was completed.
Troubleshooting
Broken tong: Remove the small nut on the eyehook connected to the tether cable and discard the remaining piece of the old tong (Fig. 35). Attach a new tong from Zap spares (using a new self-locking nut if necessary).
Figure 35: Tong and tether details
Broken strain relief on tong electric/tether cable: Using a Johnson-bar ("J-bar") or similar, slightly lift up the closest long edge of the table and insert a hydraulic floor jack (provided along with the ZapCam simulator) under the table edge. Jack the table up and use a floor stand (also provided with the ZapCam) to hold the table safely. Alternatively, the table can be carefully tilted completely up on its long edge (however, at least three people are required to do this).
From underneath the table (through the access hole), loosen the clamp (Phillips head screw) holding the electrical cable to the table base and cut off the cable crimp at the end of the cable. Unscrew the top portion of the strain relief to loosen the hold on the cable and then temporarily pull the cable completely out. Replace the strain relief from Zap spares, route the old cable through the new strain relief (or replace the cable if too short), add a new crimp on the cable beneath, and redo the electrical connection. Carefully lower the table.

COMPONENT NAME – ROLE PLAYING SPACES
Description
This space is comprised of several inter-related exhibit pieces and support "props" aimed at encouraging young visitors to role play as a medical professional and learn about basic human anatomy.
Primary Components
The primary operational components include:
Two Zap Junior area signs (with integral benches and storage chests) delineate/support the general area.
Table 1 lists details about the primary and associated components.Consumables / Spare Parts
The small play medical instruments sometimes are taken by visitors or are broken. Additionally, scrubs may rip. Available spares are listed on Table 2.
Special Instructions
Daily checks are required to ensure that all planned props are available and in good, organized condition. Check under nearby exhibit cabinets for missing pieces.
General Maintenance
Maintenance consists only of routine cleaning as specified in Table 3 (also use Table 3 to record completion of maintenance).
Troubleshooting
No sound from digital repeater: The three digital repeaters are located in the locked panel directly behind the upright exhibit back (Fig. 36). Check that main power is supplied to the repeater power adapter (output 12vDC, 1amp) and that the adapter is producing the specified current. Also, check that the speaker wiring is firmly attached (each speaker is half of a stereo headphone set). If necessary, replace the adapter or speaker/headphone from Zap spares.

Figure 37: Repeater volume adjustment
Sound too faint or scratchy from digital repeater: Each digital repeater has a volume knob that can be adjusted if desired (Fig. 37). The repeater must be pulled up out of the storage cavity slightly to access the adjustment control. Distorted sound may be caused by a bad speaker (replace if necessary).

COMPONENT NAME – BASIC ANATOMY AREA
Description
This space consists of several activities and props that facilitate learning about basic human anatomy.
Primary Components
The primary operational components (no electronics) include:
Two Zap Junior area signs (with integral benches and storage chests) delineate/support the general area.
Table 1 details the above primary and associated components.Consumables / Spare Parts
The magnetized puzzle pieces often rip and must be replaced. Also, the stuffed body organs are sometimes taken or get lost. Table 2 lists available spare parts associated with this area.
Special Instructions
Daily checks of condition and completeness of props are needed for this area. Check under the exhibit cabinets for missing pieces.
General Maintenance
Maintenance consists only of cleaning for this area. Table 3 should be followed for specific maintenance steps and their frequency. It also should be used to record that maintenance was completed.
