OVERVIEW
BLACKLINE SAFETY CLOUD
How am I connected?
The Blackline Safety Network is a cloud-hosted system comprised of 3G/4G cellular networks,
satellite networks, our Blackline Live™ web portal application, your monitoring account and
your G7
.
G7 devices require an active service plan in order to connect to the Blackline Safety Network
.
Depending on your needs and requirements, various service plan options are available such
as 24/7 safety monitoring by Blackline’s Safety Operations Center and two-way voice
communication. Contact your organization’s safety professional for more information
regarding the details of your service plan.
BLACKLINE LIVE WEB PORTAL
What is Blackline Live?
G7 utilizes the cloud-hosted Blackline Live web portal to monitor and manage all your workers
and devices, as well as deliver reports and business analytics insights.
With Blackline Live’s real-time alerting and live map with employee locations, you can quickly
locate and respond to a worker in distress. Real-time alerts show the employees’ location on
the map with the type of alert, enabling your team to efficiently send help.
Blackline Live also allows you to create and customize configuration profiles that determine
how a device or a group of devices operates in the field.

7 || G7 TECHNICAL USER MANUAL
Similarly, alert profiles are set up to determine what contacts should be notified in the event
of an incident and what response protocol monitoring personnel will follow to ensure your
team gets the help it needs
.
Blackline Live keeps track of alert history, calibrations and bump tests, eliminating theneed to
manually retrieve data logs from the field .
Blackline Live allows you to tailor user access depending on employee roles: employee,
supervisor, administrator and monitoring team
. This ensures that everyone has access to the
right tools to accommodate their role in a comprehensive monitoring program
.
What is Blackline Analytics?
With Blackline Analytics, review data collected from your device fleet to make decisions, follow
up with your team and ensure everything is running smoothly. Choose from a number of
different reports and filters to explore your data
.
Blackline Analytics is built directly into the Blackline Live portal, allowing anyone with login
access to see their own organization’s data, as well as client data. If users have only been
given access to specific groups of devices, they will only see data attached to those particular
devices
.

8 || G7 TECHNICAL USER MANUAL
G7 MODELS
There are two G7 models: G7c and G7x. The main difference between them is how they
connect to the Blackline Safety Network.
If you are unsure of which G7 model you have refer to the logo on the front of your device.
G7c
works anywhere with 3G/4G cellular
coverage in over 200 countries to connect
you directly to the Blackline Safety Network.
Depending on your service plan, your G7c
may have two-way voice capabilities.
G7x
works in conjunction with Blackline’s G7
Bridge — a portable satellite base station
that keeps you connected in remote
locations outside cellular coverage. G7x uses
a 900 MHz radio to communicate with G7
Bridge up to 2km away. One G7 Bridge can
link up to five G7x devices to the Blackline
Safety Network through Iridium satellite or
cellular data.

USING G7’S CONVENIENCE FEATURES
Much like a smartphone, G7 will include convenience features that will make it easier for device
users to do their jobs. If G7 is being used in an area where cellphones are not permitted, these
features will ensure users do not need to carry multiple devices in the field — G7 can act as an
all-in-one solution.
The timer and stopwatch features will be available from the both the main menu and the
quick-select menu. They will always be available on G7 devices using firmware version 3.450
and higher — it will not be toggleable in the configuration.
TIME
G7 now provides the option of showing the local time on the LED screen. The time will be
displayed in the top right of the main status screen. Since this is also where the check-in timer
is displayed, the user will have the option to choose what information they would like to see if
they also have the check-in timer feature enabled.
How to show local time in the banner display
The banner can display the check-in timer or the local time. By default, if your G7 fleet is
configured with the check-in timer enabled, the screen will display the check-in timer to ensure
consistency with previous behavior.

16 || G7 TECHNICAL USER MANUAL
To change the information displayed in G7’s main status screen banner:
1. Press the OK button to open the main menu.
2. Use the up and down arrows to navigate to Settings and press OK to select. Scroll to
the “Banner” option. You should see what the banner is currently set to.
3. To change the banner display, click the OK button and confirm the change. If the
banner was previously set to “Check-in”, it should now be set to “Time” and vice versa.
4. The new state will be shown in-line with the Banner display option.
How to manually change the time
By default, the local time feature will use information gathered from nearby cell towers to
determine the timezone and current time based on location, similar to how a cell phone
operates. However, a cellular connection may be unavailable, or your physical location might
be on the border between timezones. In these cases, the default settings may provide
inconsistent timezone information.
How to manually set a timezone
NOTE: Timezone offsets are relative to Greenwich Mean Time (GMT: 0:00). You may need to
look up the offset of your local timezone with respect to GMT — remember to consider
daylight savings as well if your region uses it.
1. Press OK to open the main menu. Use the up and down arrows to scroll down to
highlight the Time option and press OK to select.
2. Scroll down and select “Time settings”.
3. Select “Custom offset”.
4. On the “Set time offset” screen, use the up and down arrows to scroll through offset
options. Determine +/- (relative to GMT) first, then the number of offset hours, and
lastly the offset minutes if applicable
5. Once you have entered the offset, press the OK button to confirm. Here, you can edit
the offset if needed, or cancel if you no longer want to set an offset.

17 || G7 TECHNICAL USER MANUAL
Once you have input and confirmed the offset value you would like to use, go back to the main
status screen. The screen should now be displaying time based on that custom offset value.
If you would no longer like to use a manual offset, select the “Auto” option from the Time
settings menu and G7 will go back to using cellular information to determine the local time.
Displaying the local time on G7x
The local time feature on G7x requires a connection to a bridge running 3.450 or later in order
to use the “Auto” setting. If G7x has not connected to a bridge since starting up, or if it is
connected to a bridge running earlier firmware, a blank time (- -:- -) will be displayed. Manually
enter the correct offset for your local timezone to display the local time on the device.
TIMER
How to set the timer
1. Press the OK button to open the main menu, scroll down to the “Time” option and
press OK to select.
2. Select the “Timer” option.
3. Select the unit of time (seconds or minutes), then the amount of time.
4. Press OK to confirm your time, or select Edit to change your timer if you made a
mistake.
5. Once the timer is set, you will be able to see the remaining time in the Time menu, in-
line with the “Timer” option.
6. You can stop the timer early by selecting the “Timer” option and pressing the up button
to clear the current timer.

18 || G7 TECHNICAL USER MANUAL
How to stop the timer alarm

VIEWING G7’S ASSIGNED USER
What is an assigned user?
G7 can be assigned a team member in Blackline Live. In the G7 configuration profile, there is
also the option to display the assigned user on the device, which allows you to identify which
device belongs to which user. G7 does not have to be assigned a user to function as gas
detector.
Where can I see G7’s assigned user?
When the “display assigned user on device” option is enabled from Blackline Live, G7 will show
the assigned team member in three places (as seen in the figures below):
On startup
On the charging screen
In G7’s menu, under Advanced info > User info
On the User info screen, you will also see a team member’s employee ID, if it has been added
in Blackline Live.
