Optical safety
The following optical safety information applies to BC840-MC models with SFP interface.
This product complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to
Laser Notice No. 50, dated June 24, 2007. This optical equipment contains Class 1M lasers or
LEDs and has been designed and tested to meet IEC 60825-1:1993+A1+A2 and IEC
60825-2:2004 safety class 1M requirements.
Warning: Optical equipment presents potential hazards to testing and servicing personnel,
owing to high levels of optical radiation.
When using magnifying optical instruments, avoid looking directly into the output of an
operating transmitter or into the end of a fiber connected to an operating transmitter, or there
will be a risk of permanent eye damage. Precautions should be taken to prevent exposure to
optical radiation when the unit is removed from its enclosure or when the fiber is disconnected
from the unit. The optical radiation is invisible to the eye.
Use of controls or adjustments or procedures other than those specified herein may result in
hazardous radiation exposure.
The installer is responsible for ensuring that the label depicted below (background: yellow;
border and text: black) is present in the restricted locations where this equipment is installed.
EMC
Warning: Operation of this equipment in a residential environment could cause radio
interference.
This device has been tested and found to meet the CE regulations relating to EMC and
complies with the limits for a Class A device, pursuant to Part 15 of the FCC rules. Operation
is subject to the following two conditions: (1) This device may not cause harmful interference,
and (2) This device must accept any interference received, including interference that may
cause undesired operation. These limits are designed to provide reasonable protection against
interference to radio communications in any installation. The equipment generates, uses, and
can radiate radio frequency energy; improper use or special circumstances may cause
interference to other equipment or a performance decrease due to interference radiated by
other equipment. In such cases, the user will have to take appropriate measures to reduce
such interactions between this and other equipment.
Note that the warning above does not apply to TKH Security products which comply with the
limits for a Class B device. For product-specific details, refer to the EU Declaration of
Conformity.
Any interruption of the shielding inside or outside the equipment could make the equipment
more prone to fail EMC requirements.
