I have just picked up a used evenflo exersaucer ultra. Looks like it may need some batteries in the 20 songs and lights and in the sounds and lights device. How do I go about changing these and what size are they...how many do i need

SOURCE: I need assembly directions for evenflo exersaucer triple fun.

1. Remove toys and seat from the exersaucer.
2. Fold exersaucer, but do not let the tray lock to the base. With exersaucer flat on the floor, twist each leg assembly (B) fully clockwise until it stops. Fully depress one of the pedestal locking tabs (C) then push on the leg assembly (B); leg will partially fold. Repeat this for all four legs. After pressing the fourth pedestal locking tab (C), the Exersaucer will fold with the tray (D) rotating toward the base (E). Make sure all four tray locks. (F) are locked onto the base before trying to carry exersaucer.
3. Place your fingers beneath the legs (A) push upward to disconnect the leg assemblies from the pedestals (B). Repeat for all 4 leg assemblies.
4. After all four legs have been disconnected from the pedestals, remove tray assembly (C) from the base (D).
5. Turn tray (C) upside down and remove both end caps (E) from beneath.
6. Squeeze both locking tabs (F) on each side of the tray to disconnect and seperate the tray halves (C). 7. Connect tray halves (C) to form activity table.
7. Connect tray halves (C) to form activity table.
8. Rotate leg assemblies (A) fully clockwise until they lock into postition. Make sure all four legs lock (G) are locked properly into the uper leg pedestal (H). Also make sure all four leg locks (I) are sticking out past the edge of the tray.
9. Turn table over and install two end caps (E). Make sure both end caps lock into place. NOTE: one end cap installs from above and the other installs from below.
10. Install toys on activity table. If desired, adjust table to the appropriate height for your child. IMPORTANT: NEVER use stage 3 without end caps!

On line 16 there are downloadable instructions.

I tried to paste it in this window, but it's too large and in several different languages.
