Recording Duration
Recording duration depends on the type and
quality of the battery in use, its charge level, and
the record mode specified. Estimated duration for
different modes is specified in Appendix 1.
Installing and replacing batteries
Before starting, install the supplied battery. The
LED flashes 3 times and it will be on for about 40
sec. Now the recorder is ready to start operating.
When installing, always observe polarity (marking
on the recorder's case corresponds to the one on
the battery). Incorrect installation of battery may
lead to malfunction, which is not covered by the
warranty repair.
Supplying power for E71 and E72
For recorders with external power supply connect
a DC voltage source (3.7- 6 V) to contact 1 (minus)
and 2 (plus) of the stub coming from the Recorder
(Contact 1 is highlighted in color). In case of a Li-
Pol battery being a voltage source, battery charge
can be provided by the current of 100mA using
the connection of contacts 2 and 3 (if the adapter
is connected to the recorder and the computer's
USB).
