An electronic device and/or a method of sealing said device are configured for ease of installation and use. The electronic device has a housing having a recess, a cover concealing the recess and having walls extending circumferentially around the cover and having a channel formed in the outer surface thereof, and at least two through-holes formed through the channel, and an O-ring having a body with at least two tethers each of which passes through a respective hole in the cover.

1. A method of sealing an electronic device, comprising the steps of: providing a housing presenting an opening bounded by circumferential walls; providing a cover having walls extending circumferentially around the cover and positionable within the recess at a location inboard of the housing walls,
1. A method of sealing an electronic device, comprising the steps of: providing a housing presenting an opening bounded by circumferential walls; providing a cover having walls extending circumferentially around the cover and positionable within the recess at a location inboard of the housing walls, the walls of the cover having a channel extending around an outer perimeter of the cover walls and at least two holes formed therethrough from an inner surface of the channel; providing an O-ring having a body and at least two tethers extending inwardly from the body, wherein the O-ring body has first and second legs that are opposed with respect to one another and third and fourth legs that are opposed with respect to one another, wherein the cover has first and second walls that are opposed with respect to one another and third and fourth walls that are opposed with respect to one another, wherein the first and second tethers extend inwardly from the respective first and second legs of the O-ring body and are of a first cross-sectional shape that matches that of corresponding holes in the associated first and second walls of the cover, and wherein third and fourth tethers extend inwardly from the respective third and fourth legs of the O-ring body and are of a second cross-sectional shape that matches that of corresponding holes in associated third and fourth walls of the cover and that is different from the first cross-sectional shape; aligning like-shape tethers of the O-ring with like-shaped holes in the walls of the cover; inserting the tethers on the O-ring through the corresponding holes in the walls of the cover; stretching the O-ring body around the walls of the channel; and placing the cover over the opening so that the O-ring creates a seal between the walls of the housing and the walls of the cover. 2. The method of claim 1, wherein the cover is rectangular and the O-ring body has an at least generally rectangular shape when in its relaxed state. 3. The method of claim 1, further comprising the step of inserting a locking barb of each tether through a corresponding hole in the cover, the locking barb having a larger cross-sectional area than that of the hole. 4. The method of claim 3, further comprising the step of trimming a distal end of each tether while leaving the locking barb intact. 5. An electronic device comprising: a housing having a recess bounded by circumferential walls; a cover concealing the recess and having walls extending circumferentially around the cover and into the recess at a location inboard of the housing walls and having a channel formed in an outer surface thereof, at least two through-holes being formed through the walls from an inner surface of the channel; and an O-ring having a body with at least two tethers each of which passes through a respective hole in the cover, the O-ring body being mounted in the channel and sealing against the walls of the housing, wherein the O-ring body has first and second opposed legs and third and fourth opposed legs, wherein the cover has first and second opposed walls and third and fourth opposed walls, wherein the tethers include first and second tethers that extend inwardly from the respective first and second legs of the O-ring body and that are of a first cross-sectional shape that matches that of corresponding holes in the associated first and second walls of the cover, and wherein the tethers include third and fourth tethers that extend inwardly from the respective third and fourth legs of the O-ring body and that are of a second cross-sectional shape that is different from the first cross-sectional shape and that matches that of corresponding holes in the associated third and fourth walls of the cover. 6. The device of claim 5, wherein each of the tethers has a locking barb located between the body and an inner distal end of the tether and having a cross-sectional area greater than that of the corresponding hole. 7. The device of claim 6, wherein each tether further comprises a leader extending from the locking barb to the inner distal end of the tether. 8. The device of claim 6, wherein the cover is rectangular and the O-ring body has an at least generally rectangular shape when in a relaxed state thereof. 9. The device of claim 8, wherein the first, second, third, and fourth tethers are evenly spaced around the O-ring. 10. The device of claim 8, wherein corners of the O-ring body are molded to conform to corners of the cover walls. 11. An O-ring for sealing a cover of an electronics device to a housing of the electronics device, the O-ring comprising: a body being formed of an elastomeric material, the body forming a loop and being configured to be mounted in an outer peripheral channel formed in circumferential sidewalls of the cover and to seal against inner surfaces of circumferential sidewalls of the housing; and at least two tethers formed integrally with the body and extending inwardly from opposite sides of the body, each tether being configured to be inserted through a through-hole extending inwardly from the channel in the cover walls, wherein the O-ring body has first and second legs that are opposed with respect to one another and third and fourth legs that are opposed with respect to one another, wherein the tethers include first and second tethers that extend inwardly from the respective first and second legs of the O-ring body and that are of a first cross-sectional shape, and wherein the tethers include third and fourth tethers that extend inwardly from the respective third and fourth legs of the O-ring body and that are of a second cross-sectional shape that is different than the first cross-sectional shape. 12. The O-ring of claim 11, wherein each of the tethers has a locking barb located between the body and an inner distal end of the tether and having a cross-sectional area greater than that of the corresponding hole in the cover wall. 13. The O-ring of claim 12, wherein each tether further comprises a leader extending from the locking barb to the inner distal end of the tether. 14. The O-ring of claim 11, wherein the O-ring body has an at least generally rectangular shape when in a relaxed state thereof. 15. The O-ring of claim 11, wherein the corners of the O-ring body are molded to conform to corners of the cover walls.
