Setup
Battery Installation
The Ultra T-rex requires 4 AA batteries (not included) for its electronic functions. To install batteries:
- Locate the battery compartment, typically on the underside or back of the main body.
- Using a Phillips head screwdriver, open the battery compartment cover.
- Insert 4 new AA batteries, ensuring correct polarity (+/-).
- Replace the battery compartment cover and secure it with the screw.
Assembly
Some assembly is required to attach the legs to the main body of the Ultra T-rex. Follow these steps carefully:
- For easier assembly, it is recommended to lay the T-rex on its side when attaching the first leg. Align the leg with the corresponding slot on the body and firmly snap it into place.
- When attaching the second leg, ensure all contact points are perfectly aligned. If you encounter difficulty, re-check alignment and apply firm, even pressure until the leg snaps securely into position.
- Attach any additional accessories such as the jail, weapon storage, pterodactyl glider, ice boulder launcher, and tethered projectile claw to their designated spots on the T-rex.
