Position the Orchard Terminal such that the back of the terminal is visible before removing and replacing the battery. The open/close slide switch should then be moved to the right, then locate the battery cover. The slide switch fits snugly. After that, raise the battery cover from its base, turn the lid up, and remove it.
The battery should then be lifted from the bottom side, swung upward from the bottom, and pulled out.
The protective cover over the battery connectors must first be removed in order to install a battery. Next, place the battery in the upper right corner with the gold connectors facing down. After raising the battery, carefully press the bottom into position. The battery lid's top should then be inserted into the lid hinges, after which the bottom of the lid cover should be lowered until it is flush with the casing. The lid switch is then moved to the left.
