Warnings and Safety
STATIC ELECTRICITY
The instrument and its sensor unit (if available) contain CMOS devices and when serviced, care must
be taken to prevent damage due to static electricity. This is very important to ensure long-term
reliability of the unit. Such risk exists when both the instrument cover and the front panel are
removed.
INSIDE THE INSTRUMENT (MAINTENANCE)
When it is desired to fully restrict the access to the unit so that even its cover cannot be removed,
lockers can be mounted in the middle of the handles, on the side of the instrument. Under normal
circumstances, there is no need to remove the front panel of the instrument. In any case, only a
trained person should remove the front panel. Moreover untrained access may lead to serious
damage to the instrument, as well as may void the warranty. If the equipment is used in a manner not
specified by the manufacturer, the protection provided by the equipment may be impaired.
Before removing the front panel:
1. Turn the unit off
2. Disconnect all cables connected to the unit
3. Disconnect the battery
4. Make sure that all LED indicators are OFF
INSTALLATION SITE
This instrument is designed for highly specialized applications. If installed in publically accessible
areas it is the responsibility of the instrument owner to ensure that the device is installed in a safe
and secure manner.
The instrument should be installed in a well ventilated place and when possible be protected from
direct sunlight and heat.
The housing provides no protection against explosive atmosphere. The instrument must not be
operated without necessary protective measures (e.g. EX-proof housing) in an area where explosive
gases could be present.
BATTERY (MAINTENANCE) AND SAFETY

GMSplus User Manual
8 / 124 20.06.2017 / V21
GS_GMSplus_UserManual_V21
The instrument is usually shipped with an internal rechargeable battery (main battery), which is an
optional accessory.
In addition there is a non-rechargeable button battery (backup battery) on the circuit board of the
instrument.
NEVER use any battery other than the ones supplied or approved in writing by GeoSIG.
An external power module, which is an optional accessory, is also usually shipped with the
instrument.
NEVER use any other power module than the one supplied or approved in writing by
GeoSIG.
Do not forget to connect the main battery when installing the instrument. The main battery is
provided with a short cable that has a polarised connector to avoid any wrong connections. Please
ensure that this connector is fully inserted and secured on the mating connector inside the
instrument.
CAREFULLY observe the polarity,
when replacing the main battery:
RED cable = (+) plus terminal of the battery
BLACK cable = (–) minus terminal of the battery
when replacing the button backup battery:
(+) sign marked on the battery
Any battery MUST be replaced by following its manufacturer’s instructions regarding
actual operating conditions AND latest by the end of below mentioned replacement
intervals to prevent data loss and to avoid safety related issues:
Battery
Battery model
Replacement interval
Main Battery (Internal)
FIAMM FG20721, 12V 7.2Ah
3 years from date of production1
Yuasa NP7-12, 12V 7Ah
3 years from date of production1
FIAMM 12FGHL34, 12V 9Ah (long life)
8 years from date of production1
Button Backup Battery
Renata CR2430 MFR, 3V, 285mAh
5 years from date of production1
Duracell CR2430, 3V, 285mAh
5 years from date of production1
EEMB CR2430, 3V, 270mAh
5 years from date of production1
1assuming operation at a steady 20°C or below.
The expected lifetime of a battery can drastically change depending on operating conditions. Strong
discharge of the battery and extreme temperatures must be avoided as per specific battery
manufacturer’s recommendations and guidelines.
Lifetime and replacement intervals mentioned in this manual are based on a constant ambient
temperature of 20°C or below. If this condition cannot be met the user must check with the
documentation of the battery manufacturer for information about the battery lifetime at elevated
temperatures.
When replacing the battery only newly manufactured batteries may be installed. The replacement
interval specified above starts from the manufacturing date of the battery, which is typically found
printed on the battery itself. When replacing the battery it is the users’ responsibility to update the
“battery installation dates” parameter in the configuration as described in chapter 11.2. This
parameter is used to issue a warning of required battery change.
For safety reasons the battery and operating conditions have to be annually checked to ensure that it
is still within the manufacturer’s recommended operational criterion.
It is important that all necessary precautions about operating a battery, such as the ones installed in
the instrument, are taken into consideration and the safety instructions are followed accordingly.

GMSplus User Manual
20.06.2017 / V21 9 / 124
GS_GMSplus_UserManual_V21
The internal main battery (if installed) is a Lead Acid-type battery and is classified as “dangerous
waste”. The user is obliged to follow local laws and manufacturer’s guidelines for safe use and
correct disposal of any battery.
Lack of care or misuse of the battery as per battery manufacturer’s recommendations can be
hazardous, may damage your instrument and may even cause explosions. Please consult the battery
manufacturer’s website for the latest operating, maintenance and safety guidelines. Please contact
GeoSIG in writing if the specific safety, operating, maintenance and disposal information for your
battery type can’t be found.
SD AND COMPACT FLASH CARDS
SD and compact flash cards are available in a variety of quality levels on the market. This results in
problems with compatibility due to memory layout, signal structuring and power requirements.
Additionally some SD and compact flash card manufacturers refuse to provide adequate information
or factory controls to ensure that the product being sold today is the same as the product sold earlier
under the same part number.
Therefore GeoSIG cannot guarantee a SD or compact flash card will work in a GeoSIG instrument
unless it is purchased through GeoSIG. The SD and compact flash cards provided by GeoSIG are
tested and certified in house to work with the related GeoSIG instrument and industrial rated for
harsh environment conditions as extreme temperatures, shock, and vibration.
CLEANING
Disconnect the power from the instrument prior to cleaning. Do not remove the cover during
cleaning. Wipe all exterior surfaces with a damp cloth. Use mild detergent if required. No water
should be used if cleaning inside the instrument is required.
HOUSING LID
In case your GMSplus does not have a lid with holes as described in chapter 4.2 you must contact
GeoSIG to order a replacement lid.

GeoSIG Cybersecurity Recommendations
GeoSIG instruments, as described in their documentation, have built-in security and safety features against
unauthorised access or use. However, ultimately it is the user’s responsibility to ensure the safe and secure
usage of our instruments based on their actual implementation. No factory delivered solution can fit each and
every possible scenario. The user is advised herein that once you connect a device to a network, you are
also connecting that network to that device. It is the responsibility of the user to take appropriate precautions
so that all devices should be adequately hardened, such as with individual strong passwords, and should
have their traffic monitored and managed via appropriate security features, such as firewalls. Also, non-
critical devices should be segmented away from networks that contain sensitive information.
Compliance with a well-defined security procedure helps protect not only an individual device, but also other
devices connected through the network. Such procedure would be intended to prevent exploitation of an
individual device’s resources by unauthorized individuals, including the use of such device to attack other
systems on the network or the Internet.
The following recommendations can be considered in establishing such a security procedure:
1. Physical access restriction
All devices must be restricted from unauthorised physical access and a well-defined physical access
procedure shall be utilised.
2. No Unattended Console Sessions
Except for the devices which are physically secured, no unattended console sessions shall be left running.
3. No Unattended Network Sessions
No unattended user interface sessions shall be left running towards any device accessed through its network
interface.
4. Use of a Firewall
For a network that has any connection to the outside world, a hardware firewall must be running and
configured to block all inbound traffic that is not explicitly required for the intended use of the network and the
connected devices. The user can also consider limiting outbound traffic.
a
Any communication ports that are required for the operation must be protected.
5. No Unnecessary Services or Ports
If a service or port is not necessary for the intended purpose or operation of the device, that service must not
be running and the port must be closed. (e.g. if seedlink server is running, but not used, turn it off)
6. Use of authentication
Network and console device access must require authentication by means of strong and individualised
passwords per device (no passe-partout passwords).
Wireless access must require strong encryption to associate (such as WPA2), or some other strong
mechanism to keep casual users near the access point from using it to get full access to the network. WEP
or MAC address restrictions do not meet this requirement.

GMSplus User Manual
20.06.2017 / V21 11 / 124
GS_GMSplus_UserManual_V21
7. Password complexity and security
When passwords are used, they must meet the specifications similar to below:
a
All default passwords must be changed at time of initial access or latest at deployment
into service.
Passwords MUST:
contain eight characters or more
contain characters from AT LEAST two of the following three character classes:
Alphabetic (e.g., a-z, A-Z)
Numeric (i.e. 0-9)
Punctuation and other characters (e.g., !@#$%^&*()_+|~-=\`{}[]:";'<>?,./)
8. Privileged Accounts
Privileged and super-user accounts (Administrator, root, etc.) must not be used for non-administrator
activities. A secure mechanism to escalate privileges with a standard account is acceptable to meet this
requirement. Network services must run under accounts assigned the minimum necessary privileges.
9. No Unencrypted Authentication
All network-based authentication must be strongly encrypted. In particular, insecure services such as Telnet,
FTP, SNMP, POP, and IMAP must not be used or must be replaced by their encrypted equivalents.
10. Software / Firmware updates
Networked devices must only run software/firmware that are updated according to supplier’s guidelines. A
periodical check of any available updates from the supplier must be sought.
Please contact GeoSIG Ltd if you require any further advice or clarification.

Table 1, Storage instruction
a
Removing or replacing the backup battery must be done by a trained person only. Therefore if
the instrument is stored for more than three months, always have it connected to power and let
it run.
a
If the instrument is stored for longer than 3 months, the battery must be removed from the
instrument and stored elsewhere in a well ventilated location as per the battery manufacturer’s
recommendations. The battery must in this case be charged every six months for at least 24
hours.
3.1. Main battery
If the instrument is connected to AC power through its power supply module while stored, the main battery (if
it exists) can remain in the unit. It is highly recommended to ventilate the stored instrument by removing the
lid of the instrument.
Current leakage on main battery when unit is off, without external supply, is about 40 μA.
3.2. Backup battery
Autonomy of Real Time Clock on its backup battery is typically three years at ambient temperature. The
jumper JMP_BBATT on the main board has to be put in position 2-3 to disconnect this backup battery. This
must be done by a trained person only as a removal of the black cover is required.

4.1. Housing
The instrument is a housing mounted with a base plate. The base plate is fixed on ground and levelled one
time during installation, then the instrument can be replaced without need for levelling.
Figure 2. Instrument housing

4.2. The housing lid
If your instrument has been supplied with an internal Lead Acid battery (main battery), the housing lid will
have two ventilation holes that are covered by special membrane vents, as shown in Figure 3. A Lead Acid
battery as a matter of course will release small amounts of hydrogen which may cause an explosion under
certain conditions. A typical GMSplus housing will allow hydrogen to escape through various small openings
in the housing, however as an extra level of safety, precautionary measures have been taken by providing
two ventilation holes to allow additional air circulation within the housing. The specially applied membrane
vents will prevent external matter from entering the housing while allowing air circulation through specially
designed PolyVent membranes as shown.

Please ensure that the vents are not covered and that the instrument is not placed in a confined area without
adequate ventilation. GeoSIG will not accept any responsibility for the safe operation of the battery or any
safety related consequences that may result from using the battery.
Please consult GeoSIG in writing if you have any specific questions or require clarification with regards to
use of the battery in the instrument.
4.3. Base plate
A base plate is supplied with the instrument for fixation and levelling of instrument on site. Three levelling
feet are provided to adjust horizontally the base plate. The fixation is done as a single point in the middle of
the plate.
To ensure correct orientation when an instrument is installed on the plate, two pins are provided with the
plate. They can be mounted in different positions according to the orientation required and will fit in the two
holes existing in the base of the instrument.
A connection point for earthing is also provided with the plate as a M6 thread.
