Safety Information
This manual describes the iG5 GNSS Receiver. Before you use
your receiver, please make sure that you read and
understand these warnings and safety requirements.
Warnings and Cautions
An absence of specific alerts does not mean that there are no
safety risks involved. Warning and Caution information is
intended to minimize the risk of personal injury and/or
damage to the equipment.

iG5 User Manual 14
Use and Care
The iG5 receiver is a field ready instrument; however, it is
also a delicate electronic instrument. Take suitable care to
avoid damage to the instrument.
Avoid dropping the receiver as it can change the phase center
of the antenna.
Avoid storing the receiver at excessive temperatures (hot or
cold) as it will damage the internal batteries.
Avoid storing the receiver at temperatures less than -20° F (-
29° C) and temperatures higher than 160°F (72°C) as it will
permanently reduce the battery capacity and life
Environment
GNSS receivers and especially the Lithium-Ion batteries
contained in them are like puppies: in the summer if you
leave them in your vehicle with the windows rolled up, you
will kill them.
DO NOT leave the iG5 or accessories inside a vehicle in the
summer. Temperatures higher than 160°F will permanently
reduce battery capacity and battery life.
The receiver is suitable for use and tested in a human
appropriate atmosphere, it is not suitable for use in explosive
environments.
Risk of Electrocution: Because of risk of electrocution it is very
dangerous to use poles or extensions in the vicinity of
overhead electrical lines. Maintain a safe distance from
overhead electrical delivery systems.
If the receiver is used on a pole during an electrical storm
there is a very high risk of being struck by lightning. Do not

15 iG5 User Manual
use the product during a thunderstorm. Lay the pole down on
the ground and get away from it.
Battery Safety and Disposal
The internal batteries are lithium-ion type cells. When they
wear out, the receiver must be returned to iGage for
replacement.
Battery Warnings
WARNING - Do not damage the rechargeable Lithium-ion
battery. A damaged battery can cause an explosion or fire,
and can result in personal injury and property damage.
To prevent injury or damage:
Do not expose the receiver to fire, high temperature, or
direct sunlight.
Do not store the receiver inside a vehicle during hot
weather.
WARNING - Avoid contact with the rechargeable Lithium-ion
battery if it appears to be leaking. The battery fluid is
extremely corrosive, and contact with it will result in personal
injury and/or property damage.
If battery fluid gets into your eyes, immediately rinse your
eyes with clean water and seek medical attention. Do not rub
your eyes!
If battery fluid gets onto your skin or clothing, immediately
use clean water to wash off the battery fluid.
Battery Life
A large internal Lithium-Ion battery is installed in the receiver.
It is not user serviceable. The expected runtime is 12- to 14-
hours at normal temperatures.
For shipping regulation compliance, batteries are nearly fully
discharged when the receiver is shipped to you. You will need
to charge the receiver before first use.

iG5 User Manual 16
If you plan on running the receiver in static mode for longer
than 12-hours, it is suggested that attach an external battery
pack.
The Anker PowerCore 10000 (approximately $20 on Amazon)
style battery is a good choice and will extend receiver
operation for a full day.
Larger external batteries will extend operation for even
longer periods.
Battery Charging
When connected to the supplied charger with the receiver
turned off, at normal temperatures, the receiver will charge
about 40% per hour, to 80% and then tapper to a full charger
after another hour.
When the receiver is turned on the charging rate is slower
and the receiver may not charge past 95%.
When the receiver is plugged into a computer instead of the
supplied charger, the charging rate may be slower.

Recording Rate
The iG5 receiver is configured to automatically record raw
files with a 1 Hz rate.
The receiver has 6,741,970,900 bytes available for user
observation files. The receiver will generate approximately 14
MB per hour with normal constellations at 1Hz so
approximately 481 hours (20 24-hour days) of continuous
data can be stored on the receiver.
If you need to store data longer without downloading, you
can set the recording rate to 5-seconds or 30-seconds.
The receiver is set to automatically delete the oldest file (Ring
Buffer) as needed to record new files which will overwrite the
oldest files on the receiver.
