1. Installing Batteries in Communication Unit
(1) Remove the battery cover on the bottom of the
communication unit. The battery cover is
removed by lifting up the tab while pushing in the
direction of the arrow (OPEN).
(2) Install two size AA alkaline batteries each (total
of four batteries) in the communication unit and
battery cover while properly aligning their
polarity.
(3) Attach the battery cover.
* Securely attach the battery cover. If not attached securely, there may be defective contact
with the batteries.
* When removing the battery cover, be careful not to damage your nail.
* When charging the watch using the communication unit for the first time, the USB driver
Installation Wizard is displayed on the PC if the communication unit is connected to a PC.
Refer to the section on " Accessory Software" for information regarding installation of the
USB driver.
* The batteries in the communication unit will gradually become worn down even when not
charging. It is recommended to remove the batteries from the communication unit when not
charging the watch for a long period of time.
2. Charging the Watch
(1) Sufficiently open up the locking tab on the left side of the communication unit.
(2) Attach the watch to the communication unit so that the two center connection pins of
the four connection pins on the communication unit make contact with the two
terminals (gold) at the 3:00 position on the watch.
* In cases when a watch having a metal band cannot be connected to the communication unit
due to the band being too short, remove the leg of the communication unit (removable). Slide
the watch through the location where the leg was removed to attach to the communication unit.
WARNING
When removing the leg from the communication unit, keep the removed leg out of the
reach of children to prevent accidental swallowing.

* If the watch display is not showing before charging, simultaneously press buttons (A), (B), (C)
and (D) with the watch attached to the communication unit to perform the all reset procedure.
(Refer to the section on " All Reset" for information on the all reset procedure.)
(3) Charging will begin if the watch is properly connected to the communication unit. The
LED on the right side of the communication unit lights when charging begins, and goes
out when charging is completed (when the watch is fully charged).
(4) Sufficiently open the locking tab of the communication unit and remove the watch from
the communication unit.
* Approximately 5-6 hours is required for charging when the secondary battery is completely
drained.
* Try to recharge the watch before the secondary battery becomes completely drained. There is
no risk of overcharging no matter how long the watch is connected to the communication unit.
* When the LED does not light and the battery charge indicator of the watch does not indicate
that the watch is fully charged even if the watch has been attached to the communication unit,
the batteries of the communication unit are worn out. Replace all four of the batteries with
fresh batteries and repeat charging.
* Attempting to attach or remove the watch without opening the locking tab sufficiently may
cause the connection pins to become worn or damaged resulting in malfunction of the
communication unit.
Watch Display During Charging
Once charging begins, the watch automatically switches to
the system monitor mode (battery charge indicator) after the
diver mark in the lower left section of the watch display
flashes. ("CHRG" is displayed in the lower left section of
the display.)
* When the communication unit is connected to a PC with the USB cable, the watch displays
the USB communication display (data transfer standby display). Charging is performed while
the LED on the communication unit is lit even during data transfer with the PC using the USB
communication interface.
* When the watch has been charged to a certain extent (when all the sections of the battery
charge indicator are lit), although the diver mark remains flashing without the watch switching
to the system monitor mode, charging is still performed correctly even in this state.
* Although "CHK" may flash in the lower left section of the display during charging, charging is
performed correctly in this case as well. "CHK" is no longer displayed and the display returns
to normal when the watch is removed from the communication unit after charging is
completed.
