TESTING
7.1 Battery
Check
The presence of a battery can be verified without opening the NBHTM.
Look for the flashing LED through the window on the front of the NBHTM unit.
If the NBHTM is in an idle state, the LED will flash faintly once every second.
If the LED is not flashing, you will need to open the NBHTM and verify the presence of a
battery.
If a battery is installed and the LED is not flashing, the NBHTM will need to be initialised.
(See section on NBHTM Initialisation on page 11).
7.2 Battery
Replacement
Always wait at least 1 minute between removing a battery and either replacing the same
battery or inserting a new battery. This is to allow any residual charge within the NBHTM
to dissipate.
The NBHTM battery should only be replaced with a SAFT LSH20. This is a spiral wound
Lithium Thionyl Chloride [Li-SOCl2] battery with a terminal voltage of 3.6 volts.
Failure to replace the battery with the correct type may cause communication failure.
For further information on the battery and where to purchase replacements, please refer

WARNING
: Care should be taken when handling lithium batteries as misuse may cause
damage to the NBHTM or the battery cells may explode.
Ensure that the battery terminals are NOT shorted and that there are no loose wires in the
vicinity of the battery.
