Computer Virus Note
As a countermeasure against computer viruses, the DP21-SAL is set to inhibit write of foreign files in the system domain.
Nevertheless, it is not capable of preventing infection by computer viruses that are evolving day by day. To prevent penetra-
tion of computer viruses in the DP21-SAL, it is also recommended to take the following countermeasures.
· Perform virus check on the removal medium, such as a USB memory, before connecting it to the DP21-SAL.
· Ensure that the network and PC to which the DP21-SAL is connected are free of computer viruses.
· Should infection of a computer virus occur or be suspected, turn the DP21-SAL to OFF and unplug its power cord.
· If malfunction or a symptom of infection still persists after the above measure, please consult Olympus.
Olympus will not assume any liabilities for a malfunction of the DP21-SAL due to computer viruses as well as any trouble or
damage of the user's PC or network incurred due to computer viruses.
Battery Life
The control box D21-CB incorporates a lithium ion coin battery (CR2032) for backing up the calendar function. The service
life of the battery is 1 to 6 years (it is widely variable because the battery power consumption is reduced during operation
connecting the AC adapter to the control box D21-CB).
When the battery life has expired, STANDBY LED of the hand switch D21-HS may blink on and off.
The camera can be used even after the battery life has expired, but the calendar is reset every time the AC adapter is
unplugged.
For the battery replacement, contact Olympus.
Control Box Fan
The control box D21-CB has a ventilation fan. Be careful not to block the ventilation opening. To ensure sufficient ventilation,
install the control box D21-CB at a distance of 10 cm or more from an obstacle such as a wall.
Blocking the ventilation opening will result in malfunction or damage. Additional care is also required against penetration of
a foreign object through the ventilation opening because this may result in the fan damage. The rotation speed of the
control box fan varies depending on the system internal temperature. As a result, the fan noise may increase in the following
cases but this is not malfunction.
· When the ambient temperature is high in summer, etc.
· When the system temperature is high after long hours of use, etc.
· About 10 seconds after startup.
