The normal way to open is to turn the cover 1/4 turn CCW and the cover should
come off. However there is a small o-ring on the cover which may make the cover
stick to the case especially if it hasn't been opened for a long time. Just try to
carefully pull and/or wiggle the cover in the open position and eventually it will come off.
