ATHENS (ATH), HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX),
DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC), HONG KONG (HKG), or

■ The current time setting changes after I set it manually.
You may have the watch confi gured for Auto Receive of the time calibration signal
(page E-26), which will cause the time to be adjusted automatically according to your
currently selected Home City. If this results in the wrong time setting, check your
Home City setting and correct it, if necessary (page E-36).
■ The current time setting is off by one hour.
