Operations & Maintenance Manual: Product Specifications
Table 17. Guidance and Manufacturer’s Declaration —Electromagnetic Immunity
The GlideScope Titanium system is intended for use in the electromagnetic environment specified below. The
customer or the user of the GlideScope Titanium system should assure that it is used in such an environment.

in watts (W) according to the
transmitter manufacturer and d
is the recommended separation

electromagnetic site survey,

should
be less than the compliance level in
each frequency range.

Interference may occur in the
vicinity of equipment marked with
the following symbol:
Note: Ut is the AC mains voltage prior to application of the test level.
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the
GlideScope Titanium system is used exceeds the applicable RF compliance level above, the GlideScope Titanium system should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
GlideScope Titanium system.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
