Installing or Removing the Power Meter and VFL
To install a power meter:
1. Press and hold the On/Off button a few seconds until the unit beeps
once to put it in shutdown mode.
2. Disconnect the unit from its external power source.
3. Put on a wrist (or an ankle) antistatic strap and ensure that the end of
its wire is grounded properly.
4. Place the unit vertically so that its front panel is facing you.
5. On the top panel of the unit, locate the protective cover that hides the
power meter bay.
6. Using a screwdriver, remove the four screws of the protective cover.
Note: Keep the screws close at hand because you will need them to secure the
power meter in place later.
7. Remove the protective cover.

Do not discard the protective cover. You will need it to protect the
power meter bay if you ever send the power meter for
recalibration.
