The TC7000/7150 battery uses long life lithium based cells, the
expected continuous runtime for a TC7000/7150 from a full charged
battery pack is 6 hours (this can fluctuate depending upon actual
usage parameters). Permanent damage can be caused to Lithium
battery packs if they go into a “deep discharge” state, TC7000/7150
uses a unique method to help prevent this occurring, but the correct
battery usage and charge procedure detailed below must be followed.

BACKGROUND

TC7000/7150 monitors battery status using a coulomb counting technique which measures
the amount of energy used by the camera rather than the actual status of the battery
itself. This is different from many other non-Intrinsically Safe devices and is a result of the
certification restrictions. In order for this technique to function correctly, the camera requires
a fully charged battery to be inserted.

To help prevent the battery going into deep discharge which can cause damage,
TC7000/7150 incorporates a backup shutdown timer. After 6 hours runtime, the camera shuts
down automatically at which point, the battery should be removed and recharged as soon as
is safely possible.

If a partially charged battery is inserted, the battery status indication on the camera screen
will be removed and the shutdown timer will timeout after 2 hours, this mode of operation
is not recommended and may cause result in the battery going into deep discharge which
renders the battery unsafe and in need of replacement*

Even with the camera powered off, the Intrinsically Safe safety circuits are still functioning;
helping to ensure the camera is in a safe state. The trade-off for this continuous safety is that
the battery is being drained even with the camera powered off, which can also lead to deep
discharge. As such, at the end of a working period, the battery must be safely removed from
the camera and placed on charge, never leave the battery in the camera overnight, even if the
camera is powered off.

WARNING. ONLY REMOVE THE BATTERY IN A SAFE AREA.

CAMERA OPERATION

ALWAYS ENSURE A FULLY CHARGED BATTERY IS INSERTED
INTO THE TC7000/7150 OR POOR RUNTIME AND/OR BATTERY
DAMAGE MAY OCCUR.

TC7000/7150 will prompt the user on initial camera power up, to confirm that a
fresh battery has been installed;

• If the user answered Yes, then the battery charge status indicator will be displayed as

• If the user answers No, then the camera will display a second warning screen,
