12. IMPORTANT EXPLOITATION REMARKS. TROUBLESHOOTING
!
To ensure trouble-free and optimal use of the recorder, read this instruction manual carefully. The description of messages
and errors reported by the device is included in chapter 11.
In order to reduce the power consumption and achieve the longest possible working time without replacing the
batteries, the following recommendations must be observed (estimated working times are given in chapter 4, note 2):
- set the highest possible values
of the
Data recording interval
parameter
(recommended> 1min, chapter 9.2)
- turn off the alarms when they are not needed or set
Alarms interval
to 5s
(chapter 9.5, when the buzzer is on every 1s, it
additionally increases the power consumption by approx. 15%)
-
provide a good range with a connected mobile device and
turn off Bluetooth communication (BLE) when it is not
used (chapter 9.4.1)
- delete unnecessary files in the internal memory before starting the new recording (and check clock settings)
After removing the protective cover, there is also the option of powering up via the USB port (power supply adaptor or
powerbank, and the battery must be continuously present, because it works as a back-up power supply), however it may
cause disturbances in the device operation due to reduced resistance to harmful external factors at the installation site,
such as water, dust, power grid surges, etc.
In addition, to ensure trouble-free operation and continuous operation, it is advisable to follow the following instructions:
- do not disconnect the device from the computer's USB port before the completion of the installation of the drivers and
during the communication with the ARSOFT-CFG and LOG programs, as well as when operating the recorder's disk
(copying/deleting files, etc.), which is indicated by the [TX/RX] icon on the LCD display, moreover, do not use many
ARSOFT applications at the same time
- do not fill up the memory with your own files and folders because they reduce the capacity for recording data
- store in external memories (USB, computer disks, etc.) a copy of the current configuration file
(
AR23x.B.cfg
/
AR23x.BT.cfg
)
to
restore the configuration in case of problems or to duplicate settings
- don’t unscrew the USB cover, when condensation on the device is possible (e.g. after taking out from the fridge).
Wait until the recorder reach ambient temperature, to avoid potential malfunction. If necessary, during this time,
recordings can be stopped by programmed START/STOP key (chapter 6)
- replace the battery with a new one as soon as the device starts to indicate a low voltage level (< 3.1V), chapter 13
Turned off LCD display may indicate complete discharging, incorrect installation or lack of battery. In this case, open the
battery cover and check the correctness of the installation and voltage.
The discharging and replacement or absence of battery causes the clock to be reset and requires the time and date to be
set again after the power supply is restored (chapters 9 and 9.1), the other configuration parameters remain unchanged.
