1.2 CARE AND MAINTENANCE
Only perform the procedures described in this manual. Never disassemble your Suunto
M9i. Protect it from shocks, extreme heat and prolonged exposure to direct sunlight. If
not in use, store your Suunto M9i in a clean and dry environment at room temperature.
Wipe your Suunto M9i clean with a lightly moistened (warm water) cloth. If there are
stubborn stains or marks, you can apply mild soap to the area. Do not expose it to
strong chemicals such as gasoline, cleaning solvents, acetone, alcohol, insect
repellents, adhesives and paint, as they will damage the unit’s seals, case and finish.
Keep the area around the sensor free of dirt and sand. Never insert any objects into
the sensor opening.
1.3 WATER RESISTANCE
Suunto M9i is water resistant. Its water resistance is tested to 100m/330ft according
to ISO 2281 standard (www.iso.ch). This means that you can use the Suunto M9i for
swimming or other water sport activities but it should not be used for scuba diving or
freediving.
6
NOTE: Do not push the buttons under any circumstances while swimming or in
contact with water. Deliberate or unintentional depression of the buttons while the
unit is submerged could cause the unit to malfunction.
NOTE: Large amounts of water and dirt under the cover of Suunto M9i may disturb the
satellite signal reception.
1.4 CHARGING THE BATTERY
Suunto M9i is equipped with an internal rechargeable battery. You can recharge the
battery approximately 500 times. The life expectancy of a single charge depends on
the use of the GPS, Compass and data storage functions. When the battery level
indicator on the display reaches the red zone, the battery voltage is low. When this
occurs, you should recharge the battery. However, extremely cold weather affects
the battery voltage even when the battery is still fully operational.
If the battery warning indicator is activated in temperatures above 10°C (50°F), recharge
the battery.
Do not attempt to change the battery, as this will void warranty. Take the Suunto M9i to
an authorized Suunto dealer for a battery change.
You can charge the battery with either the included mains charger (universal mains
voltage) or through your PC’s USB connector. For other charging options see
www.suunto.com.
Charging the battery with a mains charger
To charge the battery with a mains charger:
1. Plug the charger into the mains outlet and attach
its data clip firmly to your Suunto M9i.
2. When the battery level indicator is full, disconnect the charger from the mains outlet. Your
Suunto M9i is now ready for use.
Charging the battery through your PCs USB
connector
To charge the battery through your PCs USB
connector:
1. When your PC is on, plug the USB cable into the USB port and attach its data clip
firmly to your Suunto M9i.
7
2. When the battery level indicator is full, disconnect the cable from the PC. Your
Suunto M9i is now ready for use.
NOTE: Heavy use of the GPS, backlight and compass will significantly reduce the
battery life.
WARNING
This Suunto product contains a Li-ion battery. To reduce the risk of fire or burns, do
not disassemble, crush, puncture, short external contacts, or dispose of in fire or

2.4. UNDERSTANDING GPS
2.4.1. Overview
Suunto M9i uses Global Positioning System (GPS) in determining the user’s position.
GPS incorporates a set of satellites orbiting the Earth at an altitude of 20 000 km, at the
speed of 4 km/s. The satellites send relatively weak radio signals at power levels
comparable to normal household light bulbs. So, the GPS reception gets disturbed
much more easily than, for example, cellular phone signal reception because the GPS
signals that reach the Earth are thousands of times weaker than cell phone signals.
However, due to the extreme sensitivity of the built-in GPS radio receiver, even the
faintest signals can be picked up.
2.4.2. Line-of-sight Needed
To ensure a good position measurement, there must be a line-of-sight connection
between the satellites and the receiver. This means that the objects or materials
between the satellites and the GPS receiver must not excessively attenuate the signal.
In practice, water-containing objects, such as people, trees or other dense vegetation,
can cause problems. The signals will not penetrate rocks or buildings or any metallic
materials. However, the receiver typically works well under relatively thin plastic,
fabric or wooden covers, e.g. inside boats.
2.4.3. Accuracy
To calculate a position, a GPS receiver usually requires simultaneous reception from at
least four satellites. The position accuracy typically increases with the number of
satellites being tracked but the most important factor is actually the relative geometric
position of the satellites. The best position estimate is obtained when satellites from
different directions and angles can be tracked. In other words, the less obstructed the
receiver’s view of the sky, the better the accuracy.
The accuracy also improves with the number of measurements made on the same
13
spot, as some errors will be averaged out. Under all-in-view satellite conditions a
global average horizontal positioning error is 7.8 meters (95% confidence level).
However, depending on the satellite constellation and the distortion the GPS signal
experiences when traveling through the ionosphere, the instantaneous accuracy can
vary from a couple of meters to over ten meters. The vertical position estimate is
roughly two times more inaccurate than the horizontal.
2.4.4. GPS Usage
When you turn on the GPS, the receiver starts searching for radio signals from the
satellites and as soon as one is found, data starts flowing from the satellite to the
receiver. The data includes a list of the satellite positions and the GPS time. The GPS
time is highly accurate because each satellite has an atomic clock on board.
The data flows quite slowly and usually a little less than a minute is needed for the
calculation of the first position estimate. To minimize the duration, you should maintain
an unobstructed view of the sky right after turning on the GPS. You need the satellite
positions and the GPS time before you can perform the actual position calculation and
before the GPS becomes functional. After the first position fix has been established, it
still takes additional 10 minutes before all relevant data has been received from the
satellites. The position estimate accuracy improves during this time as more satellites
can be used for position calculation.
The downloaded data is valid roughly for the next four hours during which the receiver
starts more quickly, typically in less than 10 seconds if it was turned off in between.
You should turn off the GPS when you do not need it. This is because satellite tracking
consumes large amounts of power. Suunto M9i uses the lowest power consuming
GPS technology available but you should still turn off the GPS when you do not need it.
2.4.5. Versatility
The GPS system is run by the United States Department of Defense and has been fully
operational since 1995. At least 24 operational satellites circle the globe every 12
hours in 6 orbital planes with 4 satellites per plane to provide a true global coverage.
A worldwide ground control network monitors the health and status of the satellites.
The system works 24 hours a day regardless of the weather. It can provide service to
an unlimited number of users and it is free of charge.
NOTE: The very first time you initiate the GPS, it will take longer than usual for the
14
GPS to start, as it has no reference to its current location. This may also happen if the
GPS has not been used for a long time.
Please activate your new Suunto M9i GPS at least once before sailing out. Subsequent
GPS starts will take less time. To minimize the GPS initiation time, hold the unit steady in
one position with the display facing up and make sure you are located in an open area
so that the unit has a clear view to the sky. After starting the GPS (i.e. after it has a fix),
the unit can be moved more freely without losing the connection to the satellites. The
signal strength bar on the unit’s display indicates the fix. (See section 2.1.4, GPS
Activity and Accuracy Bar Display)
