3. After completely discharging the battery pack, connect
the 375 power supply/charger to the 375 Field
Communicator and fully charge the battery. Do not
use the 375 Field Communicator on battery power
until the battery has been fully charged. However, you
can use the 375 Field Communicator with the power
supply/charger while it is being charged.
Remove the System Card and Battery Pack
To remove the System Card and battery pack:
1. Place the 375 Field Communicator face down on a
level, secure surface.
2. Loosen the two battery pack retaining screws until the
top of each screw is flush with the top of the battery
pack.
3. Slide the battery off the main unit. Do not pull up on
the battery pack as this could damage the power
supply connector.
4. Grasp the System Card and slide it straight out of the
main unit. Do not pull up on the System Card as this
could damage the card or the System Card socket.
There is no need, nor is it possible, to perform a manual
self test with the 375 Field Communicator. Testing
features are done automatically. A warning message will
occur if a fault condition is found during these tests.
The battery pack can be replaced in an Intrinsically Safe
area. The Expansion Module can be installed in an
Intrinsically Safe area while the 375 Field Communicator
is still running.
It is not necessary or possible to calibrate the 375 Field
Communicator. The 375 Field Communicator is a
communication interface that communicates digitally
with HART and F
