RD-OI-20 A/3
 If a warning sign is displayed on the viewer when the signal level of the wireless
connection displays 1 bar, check the user environment.
Note:
(1) If an acquired image can’t be transmitted because of wifi link failure, it may be possible to recover
the image later.
(2) In case of transmission failure, the last acquired image must be retrieved before any other action.
(3) In case wifi communication is no longer available, a wired connection should be used to recover
the last acquired image.
5.6 Intended Use Environment
Keep the detector as far as possible (at least 1-2m) from electronic devices that generate RF noise like
microwaves, monitors, or electric motors.
Try to keep the antennas at least 15cm away from the wall or other objects. Wifi quality may also
depend on access point position and antenna orientation.
6 Announcement
6.1 Basic Notices
Please read this operation manual carefully before using the detector in order to ensure safety and
correct usage. Keep this manual for reference.
6.1.1 Use-method of Power Supply
First, connect the power box with the detector. Then, connect the AC power cable when powered on.
Do not forcefully connect the AC power box when the detector is not well connected, as it may result
in damage to the power interface port.
First, shut off the power switch, then disconnect the connector of the AC power cable when the device
is completely powered off. Do not forcefully disconnect the interface cable between the power box and
the detector, as it may short circuit, leading to damage to the battery or causing it to ignite.
6.1.2 Network
The network used between the DROC station and the detector should not be connected via public
Ethernet, otherwise data transmission speed may be reduced and the network connection maybe
rendered invalid or have safety issues.
Note: In case the network link is extended, the LAN cable must be file transfer protocol(FTP) or
shielded twisted pair(STP) type, category 5 or above (5E or 6).
