To remove the power meter for recalibration:
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 power meter.
6. Using a screwdriver, remove the four screws of the power meter.
Note: If you have a protective cover for the power meter bay, keep the screws
close at hand. You will need them to secure the protective cover in place
later.

Do not discard the screws. You will need them to secure the power
meter in its bay when it is back from calibration.
