l Dispose of the used battery according to the instructions provided by the manufacturer.

l Do not dispose of the lithium battery in fire.

1.5 Radiation

Electromagnetic Field Exposure

CAUTIONHigh power radio-frequency signals are harmful to human body.

Before installing or maintaining an antenna on a steel tower or mast with a large number oftransmitter antennas, the operator should coordinate with all parties to ensure that the transmitterantennas are shut down.

The base transceiver station (BTS) has RF radiation (radiation hazard). Suggestions for theinstallation and operation of BTSs are given in the following section. Comply with the localregulations when installing the BTS.



1-7

Forbidden Area

Comply with the following requirements:

l The antenna should be located in an area that is inaccessible to the public where the RFradiation exceeds the stipulated value.

l Before entering the area where RF radiation exceeds the stipulated value, the staff shouldknow the location of the area and shut down the transmitters. Such an area may not exist;but if it exists, the area must be within a range of less than 10 m around the antennas.

l Each forbidden area should be indicated by a physical barrier and striking sign to warn thepublic or staff.

Laser

CAUTIONWhen handling optical fibers, do not stand close to, or look into the optical fiber outlet withunaided eyes.

Laser transceivers or transmitters are used in the optical transmission system and associated testtools. Because the laser that is transmitted through the optical fiber produces a small beam oflight, it has a very high power density and is invisible to human eyes. If a beam of light entersthe eye, the retina may be damaged.

Normally, staring into the end of an unterminated optical fiber or broken optical fiber with theunaided eyes from a distance of more than 150 mm [5.91 in.] will not cause eye injury. Eyesmay, however, be damaged if an optical tool such as a microscope, magnifying glass or eyeloupe 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 cannotensure 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 lookinto 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 fromthe optical source. After disconnecting the optical fiber, use protecting caps to protect allthe optical connectors.
