FEATURES
CHARGING G7
How does G7 Dock charge my G7 personal safety monitor?
G7 devices will automatically start charging when placed into a powered G7 Dock. It will
take a maximum of four hours to fully charge G7.
NOTE: If G7 is not charging, conrm that G7 Dock is powered, the charge clip is clean of
debris and G7 device is properly placed on the dock charge clip.
BUMP TEST
What is a bump test?
Bump tests are a safe practice to regularly test alarm indicators (lights, sound and
vibration) on G7 by applying enough gas to the sensors to trigger an alarm.
G7 communicates bump test data automatically to the Blackline Safety Network, and
will remind you when a bump test is overdue. The bump test schedule is congurable.
NOTE: To meet CSA LEL performance standard, you are required to bump test before
each day’s use. Blackline recommends you do not exceed 30 days without a bump test.
Overdue bump test
If your G7 device is overdue for a bump test according to its conguration, it will
automatically begin a bump test when placed into G7 Dock.
How do I perform a bump test that is not overdue?
1. Power on G7 device
2. Place G7 into G7 Dock
3. Close the lid until it clicks in place
4. Press G7’s arrow buttons to navigate to Bump Test on the LCD screen menu

G7 DOCK TECHNICAL USER MANUAL || 15
CALIBRATION
What is calibration?
Gas sensors periodically need to be calibrated by applying a known concentration of
gas for a set amount of time. This procedure ensures the gas sensor can accurately
detect gas levels throughout its operating life. The calibration schedule depends on
your company’s safety policy. Blackline recommends not exceeding 180 days without
a calibration.
Calibration Settings
G7 devices have their own gas calibration settings, which can be modifed in Blackline
Live. If the device’s congured gas settings do not match G7 Dock’s settings, the
calibration will continue using dock’s settings as a default. As long as G7 Dock is
congured correctly to the gas concentrations being used, the calibration will be
successful.
Overdue calibration
If your G7 device is overdue for a gas calibration, it will automatically begin calibrating
when placed into G7 Dock.
How do I perform a calibration that is not overdue?
1. Power on G7 device
2. Place G7 into G7 Dock
3. Close lid until it clicks in place
4. Press G7’s arrow buttons to navigate to Calibration on the LCD screen menu
5. Press G7’s OK button to select Calibration
6. G7 dock will perform the calibration
7. G7 will let you know if the calibration has passed or failed and when it is ready
to be removed from G7 Dock
G7 DOCK UPDATE
To make changes to your G7 Dock conguration, please contact our Customer Care
team who can assist you with over-the-air conguration updates.

MULTI DOCK SETUP
What is a multi dock set-up?
In situations where multiple safety monitoring devices require calibration and bump
testing, docks can be joined together to perform these functions across all connected
devices. Multiple G7 Docks can be connected to a single gas cylinder by using tubes,
check valves and T-connectors. One gas cylinder is able to support five G7 Docks at
one time.
What do I need for a multi dock set-up?
G7c or G7x personal safety monitoring devices (single or quad cartridge)
G7 Docks for each device
Tubing (1/8” inner diameter)
Nylon or polyethelyne T-connectors
Nylon check valves
Gas cylinder with specic multi-gas mixture
120/240 VAC Power source for each dock
How do I calibrate and bump test multiple devices?
G7 Docks in a multi dock set-up act independently of each other - calibrations and
bump tests are carried out in the same manner that they would be if they were set
up separately. This means that docks connected to the same gas cylinder can do
calibrations and bump tests at the same time without interferring with each other.

G7 DOCK TECHNICAL USER MANUAL || 17

G7 DOCK TECHNICAL USER MANUAL || 19
CALIBRATION AND BUMP TESTS
Why are my calibrations and bump tests failing?
Calibrations and bump tests can fail if there is not enough gas reaching the sensors. To
ensure that gas is owing from the gas cylinder to G7 Dock, check that:
There are no kinks or crimps in the tubing
The gauge on the gas cylinder indicates there is gas inside
The gas cylinder is using a demand-ow regulator
The quick-connects are properly connected to G7 Dock
Gas concentrations in the gas cylinder match device and dock congurations -
congurations can be changed over-air with Customer Care
