1. TIME MODES [\ DIVING MODES

In any mode (except the Dive Mode), pressing button

for 2 seconds or more

sounds the confirmation beep and switches between the Time Modes and the

Diving Modes.

• When the Dive Mode depth meter display reads 0 (within 1m/4ft), depth

measurement ends and the watch switches to Time Modes display.

• When the Dive Mode depth meter display reads 1.0m (4ft) or more, the

mode cannot be switched by button operation.

• If the low battery warning function is activated or if there is something wrong

with the pressure sensor (ER is displayed), normal depth measurement can-

not be carried out so the watch cannot be switched to the Dive Mode of the

Diving Modes.
