1.Z1 USER MANUAL
Whenever you go diving we recommend that you always have access to
this manual as understanding and using the functions of the Z1 ensures
safe and enjoyable diving.
This is a dive computer to support no decompression diving safely. The
solar panel generates electric power to run the Z1. The Z1 has multi-
functions as a watch, alarm, timer, stopwatch, directional compass and
angle, world time watch in the Watch Mode, and surface interval time
and desaturation time (DESAT time) in surface interval. In the Dive Mode,
information of water depth, water temperature, dive time, ascent speed
and decompression are provided.
The Z1 is compatible with a mixture of four different Nitrox gases.
Comprehensive accelerated decompression is possible because each
fraction of oxygen (O2%) can be set from 21% to 100% in 1% increments.
The calculation model we use for the decompression program of the Z1
is based on the decompression theory of Dr. A. A. Buhlmann - Buhlmann
ZHL16C Algorithm.
Before use you to need understand all warnings and cautions of the Z1
written in this Instruction Manual. To avoid any serious accidents, please
make sure to read and fully understand the Z1. If you have any questions,
please ask the shop where you purchased the Z1.

When you notice abnormal conditions on the Z1, stop using it immediately
and contact the shop where you purchased the Z1.
Make sure to completely understand, How to use, Warnings, and Cautions
of the Z1 in this Instruction Manual before use. Confirm that you under-
stand how to use the Z1 in closed water in a pool before using in open
water.
When using the Z1 in scuba diving, you need to first take a dive training
course both in learning rules and practical skills, and obtain a Certification
card issued by internationally acknowledged dive training organizations.
(You can use the Z1 in the training under the guidance of instructors of
such organizations)
Before using the Z1 in Nitrox (EANx) dive, you need to take and complete a
Nitrox (EANx) dive training course. Otherwise, do not use the Z1 in Nitrox
(EANx) dive.

• If the secondary battery is removed from the Z1, be careful that small
children do not swallow it. Put the battery out of reach of children. If
swallowed, contact a doctor at once.
• Check the battery power level is “H” before diving. If the power level gets
low and a warning is displayed while diving, safely exit as soon as possible
and recharge the Z1.
* Even if this warning is displayed during a dive, there is sufficient power
for the remaining dive. Deal with the situation calmly and without panic.
Ref. Low Power Alarm•••P.15
• Follow the displayed warnings and messages for cautions on the Z1 at
once.
• When using the Z1, also use other devices as another dive computer,
divers' watch, and/or depth indicator together as a backup device.
• The Z1 is to be used for recreational diving only. Do not use the Z1 for any
other diving.
• Never lend or share the Z1 with anyone else if residual nitrogen still
exists in the body after using the Z1.
• Make sure to set O2% in every dive. It is extremely dangerous if the O2 %
in tank and the Z1 don’t match.
• Dot not disassemble, repair, modify, exchange the secondary battery or
conduct pressure chamber test on the Z1 by yourself. This is extremely
dangerous and may causes malfunction. Please see authorized center for
any maintenance.
• The Z1 is designed for dives with compressed air (21% 02) and Nitrox
(22% to 100% 02). The Z1 cannot be used with any other mixed gas.
• Each diver should be responsible for planning and conducting safe dives
in accordance to each diver’s condition.
• Please practice safe diving, do not exceed the displayed data in the
Z1. The Z1 cannot prevent you from developing decompression illness
completely.
• The Z1 does not measure, display and control the air pressure in the tank.
Use a residual air pressure indicator to check and monitor tank pressure
by yourself.

• Since the metal part of the main body and band may rust from dirt and
contaminate the cuffs of clothing, please keep the Z1 clean at all times.
Especially after immersion in seawater, wash thoroughly with fresh water
to avoid any corrosive build up.
• Since the main body and the band are in direct contact with the skin,
there is a risk of causing a rash, depending on how the Z1 is maintained
and the conditions during use.
1. Allergy to metal and resin
2. Dirt, rust, sweat etc. of the main body of the product and the band
3. Physical condition etc.
·
Tightening the band makes it easier to sweat and makes the path of air
worse, so it becomes easier to get a rash. For everyday use, please use it
with a loose fit.
· In the unlikely event that abnormality occurs, discontinue use and consult
a doctor.
• Please ensure the contents of log data etc are stored and saved
separately from this product by keeping written log or other means. A
malfunction of this product, repair or battery exhaustion may cause
stored contents to disappear.

remove this product at bedtime.
• When you hold or touch an infant, please remove this product to prevent
rashes caused by allergies or other medical conditions.
• When the product protection sticker is affixed to the main unit (including
the back cover) or the band, please be sure to peel off before use. If you
use it without peeling off the seal, dirt may adhere to the gap between
"main body and band" and "seal", which may cause rust and skin irrita-
tion.
• If while wearing the Z1, the auto light operating condition is on or acti-
vated while driving a car etc, please stop it as it may hinder driving and be
dangerous.
CAUTION
• Danger of explosion if battery is incorrectly replaced. Battery must be
replaced with the same or equivalent type - see authorized service center.

4. Things To Check Before Using the Z1
4-1. Check the battery power level.
Before using the Z1, "charging" and "setting time and date" are required.
Please fully charge and match the time and date display before use.
4-2. Charged with light (solar charge)
The Z1 operates with a battery (secondary battery) charged with electricity
generated by a solar panel.
•The solar panel is integrated within the dial.
•When sufficient light hits the dial, it will charge the battery.
When using, please try to ensure light hits the dial (solar panel).
4-3. How to charge
Whenever you are not wearing the Z1, leave it in a location where it is
exposed to light. Once every month, if you charge it against sunlight for
half a day, you can use it in a more stable condition. When wearing the
Z1, make sure that its face is not blocked from light by the sleeve of your
clothing. If the dial (solar panel) is partially hidden, power generation
efficiency will be reduced.
Leaving the Z1 in bright light for charging may cause it to become quite
hot. Take care when handling the Z1 to avoid burn injury. The Z1 can
become particularly hot when exposed to the following conditions for long
periods.
- On the dashboard of a car parked in direct sunlight
- Too close to an incandescent lamp
- Under direct sunlight
Allowing the Z1 to become too hot can cause its liquid crystal display to
black out. The appearance of the LCD should become normal again when
the Z1 returns to a lower temperature.
Check the state of charge with [H] [M] [L] at the bottom of the screen.
[H] or [M] displayed.
The Z1 is charged sufficiently.
Set the current time. See "Configuring
Current Time and Date settings.
[LOW] is blinking on the display.
[L] is blinking on the display.
[CHG] is blinking on the display.
Power is low.
Charge the Z1 by placing it in a location
where it is exposed to light.
CAUTION

15
4-4. Insufficient Charge or out of Charge
You can get an idea of the Z1's power level by observing the battery power
indicator[H][M][L] on the lower display.
•When the charge amount decreases, the functions that can be used are
limited. When charging becomes insufficient, please charge by lighting
the dial (solar panel).
IMPORTANT
• At out of charge, all functions are disabled and settings return to their
initial factory defaults.
When making various settings such as time and date, please charge until
the display at the bottom of the screen becomes [M] or [H].
Ref.
• Leaving the Z1 exposed to direct sunlight or some other very strong light
source can cause the battery power indicator to show a reading tempo-
rarily that is higher than the actual battery level
• The correct battery level should be indicated after a few minutes.

4-6. Low Power Alarm
For safe diving, when power becomes too low to dive, low power alarm is on
with a message to urge divers to recharge the power. Since sensors of the
Z1 would not function when power level becomes [L], dive is not allowed.
Suppose you started dive with the power level [M], and it becomes [L]
while dive, no information related to the dive is shown anymore. To avoid
this dangerous situation, when power becomes too low to dive, you cannot
dive until the power becomes high enough for dive.

4-7. Power Saving
When turned on, Power Saving enters a sleep state automatically when the
Z1 is left for a certain period in an area where it is dark from 10:00PM to
6:00AM.
•The table below shows how the Z1 functions are affected by Power Saving.
