10.1.1 Battery
Replacement
The Tail Flick Unit memory is supported by a battery snaphat type
M4T32-BRI2SH1
of
ST. The rated battery endurance is 10 years, therefore replacing the batteries is not a
frequent task.
When the batteries are exhausted, the dis-
play shows the caption “
MEMORY LOSS!!
”.
To replace batteries, first of all switch off the unit and disconnect the mains cable
!
N O T E :
when the caption “
MEMORY LOSS!!
” appears, the internal memory is lost.
The loss of relevant data can be avoided by
saving data before exiting any
experimental session
, see also paragraph 0-This command can be useful,
for instance, before starting a new experimental session, if the operators pre-
fers to cancel the data saved from previous experiments.
The Memory menu automatically appears also when the memory is
fully
loaded
, which means it has reached its maximum capability of about 300
measures.
“Memory Full” Message
Always use the same type of batteries for replacement, our part number
E-US 063-1
see
paragraph 12-ORDERING INFORMATION.
The batteries are located on the PCB of the controller; Take off the bottom panel of the
Tail-Flick Unit by removing its four screws.
If needed, wiring diagrams are available; please contact our Customer Support, see par-
agraph 10.5.
You will notice a mini PCB, assembled on a larger one. On the mini-board there is a
small box, marked U3. This 4-pin box contains the batteries and the clock quartz. Extract
it with care, by lifting its longer sides with the help of a miniature screwdriver.
Insert the fresh snaphat paying attention to its orientation; its white dot should match the
dot on the PCB. A “click” assures you that a proper insertion took place.
Reassemble the bottom panel.
To restore the configuration, you have to restore the standard factory parameters first:
depress the
F1
key and keep it depressed for some seconds, then depress together
F4
.
The caption “
DEFAULT PARAMETERS RESTORED
” confirms the action.
