Step 2: Remove battery

You remove the battery only if you intend to use the battery from the old controller canister in the new controller canister.

1. Press down on both of the top cover latch buttons on the old controller canister, and slide the top cover to the rear of the canister.
2. Perform one of the following options, depending on your model of controller-drive tray, to release the old battery:
   • For the E2600 controller-drive tray or the E2700 controller-drive tray, unscrew the thumb screw that secures the battery to the controller canister.
   • For the E5400 controller-drive tray, the EF540 controller-drive tray, the E5500 controller-drive tray, the EF550 controller-drive tray, the E5600 controller-drive tray, or the EF560 controller-drive tray, release the tab that secures the battery to the controller canister.
3. Remove the battery by sliding it towards the rear of the old controller canister.
