Tools

1. Step 1 Antenna
  Remove the battery cover by sliding it down.
  
  Firmly grasp the battery and pull to disconnect the battery from its connector.
  
  Using a Phillips #00 screwdriver, unscrew the two 5.0 mm Phillips #00 screws located at the bottom of the monitor inside of the device.

2. Step 2
  Using a plastic opening tool or spudger, pry apart the front case from the back. There are many access points, but the best spot to insert the spudger is around the "TALK" button.
  
  Avoid using the metal spudger. When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.

  Find the label “ANT2” on the motherboard on the left of the top right screw hole. This is where the antenna connects to the motherboard. Desolder the antenna and remove the wire carefully.
