The “AKAREL” is the heart of the BATM, and is itself composed of several discrete components.

  • This guide describes the AKAREL7, which is used on some models of the BATMTwo.

ALWAYS unplug your BATM before attempting disassembly or installation.

WiFi Antenna

The WiFi antenna is attached to the door, facing outwards, covered by the GB label. The other end is a U.FL micro-coax cable fitting and it simply presses onto the socket located on the coreboard.

  • REMOVAL: Gently lift the WiFi cable connection up & off with a screwdriver.

  • ATTACHMENT: orient the fitting over the socket and press gently down. The cable should be oriented as shown for proper seating.

LCD display connectors:

The LVDS (Low-Voltage Differential Signaling) cable provides the screen details (pixel control).

  • Possible symptoms of malfunction include: scrambled video, lines in video, missing colors.

The backlight cable provides power to the display panel.

  • A typical symptom of malfunction is no video (a “dead screen”).

For the technically adept, the other ends of these 2 cables connect to the LED display panel.

2. Remove the four mounting nuts:
