Section 3 Before Recording
Starting and terminating the main unit of es8.
3.1. Cautions as to Power Supply
.
Power Supply
The main unit operates by an AA cell battery×4. Recording can last continuously for more than 3 hours by an Oxiride battery of standard accessory.
In the case of long periods of operation by an internal battery, we recommend you use a NiMH type battery (i.e.: NiMH battery: Panasonic HHR-3SPS
Meta-high 2400 series). This battery makes it possible to record for about 4 hours. We also recommend you use an NiMH type battery under the temperature
of 0
℃ 〜
40 ( However, it should be within the range of
℃
spec).

Battery Setting
Slide the cover on the bottom panel toward
the direction of the arrows.
To confirm the voltage of the back up internal battery, please refer to “3.6. Confirming the supply voltage and operational settings when the battery voltage
is low”. And when the total voltage of the cell battery comes down to lower than 4.2V in the case of using an internal cell battery alone, the system comes into
the state of low battery voltage.
Use attached AC adaptor (A05C1-12MI) whenever using the AC supply.
An external power supply is available, in that case, the power supply voltage range is defined as 8VDC
〜
15VDC. External power supply operation should
precede internal battery one when both are simultaneously available. Rating of 0.2A or more should be used in the case of 12VDC.
The specification of DC IN connectors of the main unit is compatible to EIAJ RC-5320A and Voltage category 4. Polarity is as follows.
CAUTIONS
Be careful of the polarity when connecting the external DC power supply to the DC IN connector.
Please use the attached adaptor without fail when using the AC supply.
Action of es8 when the external supply has a low battery or when instaneous power failure occurs
When es8 has an internal battery, you can choose the action from the following two items when the external battery supply is low or instantaneous power
failure occurs.
Stops recording and starts file closing. If the external supply recovers, es8 restarts to record it as new file.
Keeps on recording with the internal battery. If the external supply recovers, es8 switches to the external one and keeps on recording. If the external supply
does not recover, it stops recording and starts the file closing when the internal battery comes into a low state.
Refer to “3.6. Confirming the supply voltage and operational settings when the battery voltage is low” for settings.
Internal Back-up Battery
Setting the parameters for power-on status or record recovering action after power failure is saved on SRAM. This SRAM is backed up by an internal back-up
battery. Refer to “3.6. Confirming the supply voltage and operational settings when the battery voltage is low” for confirming the voltage of the internal
back-up battery. Any problems will not occur in back-up action so long as the voltage shows 2.8V or more under normal use.
