Acumen Stopwatch - Manual (Page 19)

When the light on the Charger turns from red to green, indicates the battery
is fully charged.
(Note: For the purpose of watch only, the battery will last for
about 3 weeks. If you fully utilize the Fluid Loss and Heart Rate features
(optional) for 1 hour everyday, the battery has to be re-charged for every week.)
Note:
1) The first time you try connecting the watch to the connector. Center the connector so
that it is guided between the 2 mode buttons on the watch before it is fully inserted.
2) The bottom tab on the connector when properly inserted should be flush with
the bottom of the watch. (as shown in Figure 3)
3) When the watch and connector are properly connected, the LED on the
Charger will light up as red.
4) To achieve the best performance out of the watch battery, it is recommended to
charge the watch for at least 12-hour before its initial use.
5) If you fully utilize the Fluid Loss and Heart Rate features for an average of 1-
hour a day, you are recommended to recharge the watch once a week. (For
Time purpose only, the watch should last about 3 weeks.)
6) To ensure a longer period of the battery life, we recommend you to charge the
battery immediately when the low-battery warning (i.e. "LOW BATT." ) appears
on the watch.
7) After the first low battery warning comes on for 15 minutes, the EL, Heart Rate,
Humidity & Temperature features will be turned off in saving the battery energy.
8) When you charge the watch after it shut down, it will first enter Time & Calendar
Setting Mode automatically, that enable you to adjust the time and calendar for
the watch. After you finish the setting, it exits to the normal mode. Your personal
settings and exercise data for your last exercise are well kept by the watch.
Step 2: Use the supplied Transformer, one end connect with the PC
Interface and Charger (for EON-3068HS) or Charger (for EON-3067HS),
the other end plug into a proper voltage AC wall outlet.
