Dive Planning:
Once the IQ-400 has been activated, touch the
PLAN and MODE/ PLAN contacts.
Clock:
Once the IQ-400 has been activated, touch the
MODE and MODE/ PLAN contacts for two

When the MODE and MODE/ PLAN con-

Logbook Memory:

Time Setting:
at Set the time and date can be adjusted.

by covering both contacts with your right thumb. Without lifting your right
thumb, touch the MODE/ PLAN contact with your left thumb. Alternatively,
