(2) Attach the watch to the charger so that the two center connection pins of the four connection pins on the right side of the charger make contact with the two terminals (gold) at the 3:00 position on the watch.
* If the watch display is not showing before charging, simultaneously press the lower right button (A), upper right button (B), upper left button (C) and lower
left button (D) and then release with the watch(2) attached to the charger to perform the all reset
procedure. (Refer to the section on "All Reset" for information on the all reset procedure.)

(4)Sufficiently open the locking tab of the charger and remove the watch from the charger.
*Approximately 7 hours is required for charging when the energy storage cell of the watch is completely discharged.
*Try to recharge the watch before the energy storage cell of the watch becomes completely discharged. There is no risk of overcharging no matter how long the watch is connected to the charger.
*When the LED does not light and the charge level indicator of the watch does not indicate that the watch is fully charged even if the watch has been attached to the charger, the 4 pcs. of size AA alkaline batteries of the charger are worn out. Replace all 4 pcs. of size AA alkaline
batteries with fresh size AA alkaline 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 charger. However, please note that opening the locking tab beyond what is necessary can damage the locking tab.
*This charger has been designed for use with CYBER AQUALAND Nx equipped with an original urethane band. Please note that if this charger should happened to be used with a different band other than the original urethane band or the urethane band is replaced with a metal band, the contacts of the watch and charger may become unstable, thereby preventing the watch from being charged properly.

*When the watch has been charged to a certain extent (when all the sections of the charge level 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 charger after charging is completed.
