Electronic Unit
The GSM electronic unit is battery op-
erated. Its internal rechargeable bat-
tery is charged automatically when ex-
ternal power is supplied to its minia-
ture USB ‘B’ socket, either from a PC
or from a suitable USB power adapter.
A fully charged battery will operate
GSM continually with its display at
maximum brightness for approximate-
ly 16 hours.
When GSM is switched
OFF
, it goes
into a standby mode in which it takes
almost no current from the battery alt-
hough it still updates its internal cal-
endar clock. GSM is switched
ON
by
pressing the
ON/OFF
button.
GSM uses the three buttons below the
display as
soft buttons
whose func-
tions change at different stages of the
GSM program.
