Pearl Harbor officials are warning residents in the area that their remotely operated garage door openers may be temporarily affected by increased radar activity from warships participating in the Rim of the Pacific exercise that begins on Thursday.

The Rim of the Pacific Exercise involves 25,000 participants from several Pacific nations and runs through the end of July.

The Navy, in a written statement, said it is required to test surface search radars in port prior to getting underway.

Remotely controlled garage door openers operate at a low power and can be affected by electromagnetic activity generated by Navy ships and other sources, the Navy said.

To ensure garage door openers function properly, the Navy advised owners to check with their door company.

The state estimates that the international naval war games will generate $52.5 million through purchases of supplies, fuel and food, and spending by family and friends of participating personnel.
