BATTERY REPLACEMENT
We recommend that you should take it to a local jewelry
store or an authorized Acumen service center in order to
guarantee that it will maintain its water resistance. Improper
battery replacement or service will void the warranty. If you
feel comfortable replacing your own batteries, be careful to
notice how the old battery comes out and the proper
positioning of the hold-down contacts before removing it.
Also, be careful to line up the o-ring gasket properly before
replacing the battery door cover. To insure battery water
resistance, it’s a good idea to smear a small drop of silicone
lubricant spray on the rubber o-ring.
Note: The watch will enter the shelf mode (i.e. blank screen)
after changing battery. Press any button to return to normal
mode.
