APM30




24/151

l The antenna should be located in an area that is inaccessible to the public where the RF

radiation exceeds the stipulated value.

l If the areas where RF radiation exceeds the stipulated value are accessible to workers,

ensure that workers know where these areas are. They can shut down the transmitters before

entering these areas. Such areas may not exist; but if they exist, the areas must be within arange of less than 10 m around the antennas.

l Each forbidden zone should be indicated by a physical barrier and striking sign to warn the

public or workers.

Laser

CAUTION

When handling optical fibers, do not stand close to, or look into the optical fiber outlet with

unaided eyes.

Laser transceivers or transmitters are used in the optical transmission system and associated test

tools. Because the laser that is transmitted through the optical fiber produces a small beam of

light, it has a very high power density and is invisible to human eyes. If a beam of light enters

the eye, the retina may be damaged.

Normally, staring into the end of an unterminated optical fiber or broken optical fiber with the

unaided eyes from a distance of more than 150 mm (6 inches) will not cause eye injury. Eyes

may, however, be damaged if an optical tool such as a microscope, magnifying glass or eye

loupe is used to stare into the bare optical fiber end.

Read the following guidelines to prevent laser radiation:

l Only the trained and authorized personnel can perform the operation.

l Wear a pair of eye-protective glasses when you are handling lasers or optical fibers.

l Ensure that the optical source is switched off before disconnecting optical fiber connectors.

l Never look into the end of an exposed optical fiber or an open connector if you cannot

ensure that the optical source is switched off.

l To ensure that the optical source is switched off, use an optical power meter.

l Before opening the front door of an optical transmission system, ensure that you are notexposed to laser radiation.

l Never use an optical tool such as a microscope, a magnifying glass, or an eye loupe to look

into the optical fiber connector or end.

Read the following instructions before handling optical fibers:

l Only the trained personnel can cut and splice optical fibers.

l Before cutting or splicing an optical fiber, ensure that the optical fiber is disconnected from

the optical source. After disconnecting the optical fiber, use protecting caps to protect all

the optical connectors.

2.4.2 APM30 Working with Mini BaseStations

The typical configuration for the APM30 working with a mini base station is one APM30, one

extended battery cabinet, one mini base station, and the transmission equipment. The

transmission equipment is optional. Whether to configure the transmission equipment depends

on the actual conditions.

When the APM30 works with a GSM mini base station, an extended battery cabinet is requiredto back up power for the mini base station, as shown in Figure 2-7.
