Health Limits for Encompass 4H Reader Using



Integrated Antenna (902 to 928 MHz)

Within the United States, environmental guidelines regulating safe exposure lev-

els are issued by the Occupational Safety and Health Administration (OSHA).

Section 1910.97 of OSHA Safety and Health Standards 2206 legislates a maxi-

mum safe exposure limit of 10 milliwatts per square centimeter (mW/cm2) aver-

aged over 6 minutes at 915 MHz.

Although not binding, other organizations such as the American National Stan-

dards Institute (ANSI) and Health Canada Safety Code 6 (2009) have issued simi-

lar guidelines that are more restrictive than the OSHA limits (ANSI C95.1).

Health Canada Safety Code 6 guidelines recommend a maximum safe power den-

sity in W/m2, 0.02619ƒ0.6834.

Thus, the maximum permissible exposure for general population/uncontrolled

exposure at 915 MHz is 2.77 W/m2. The power limit is a six-minute average.

The RF power density generated by the Encompass 4H Reader was calculated

using a maximum antenna gain of 11 dBi, equivalent to the antenna gain of the

integrated antenna.

Warning

At 0.291 W transmitted power and a distance of 13 inches (33 cm) from the

reader, the maximum power density calculated was less than 2.77 W/m2. Install

the reader at least 13 inches (33 cm) from the general public. Maintenance per-

sonnel must remain at least 4.8 inches (12.3 cm) from reader when system is

operating.

The data confirms that the TransCore Encompass 4H Reader effectively meets

OSHA requirements and thus does not represent an operating hazard to either the

general public or maintenance personnel.

Encompass 4H Reader System Guide

Limites d’innocuité du lecteur Encompass 4H utilisé

avec une antenne interne (902 à 921,5 MHz)

Aux États-Unis, les directives environnementales concernant les niveaux d’exposition

acceptables sont émises par l’OSHA (Occupational Safety and Health Administra-

tion).

L’article 1910.97 de la norme de santé et de sécurité 2206 de l’OSHA fixe la limite

d’exposition acceptable à une moyenne de 10 milliwatts par centimètre carré (mW/

cm2) sur une période de 6 minutes à 915 MHz.

D’autres organismes de normalisation tels que l’ANSI (American National Standards

Institute) et le Code de sécurité 6 de Santé Canada ont émis des directives similaires,

mais non obligatoires, qui fixent des limites plus restrictives que celles de l’OSHA

(notamment la norme ANSI C95.1). Les normes de Santé Canada Code de sécurité 6

recommandent de ne pas dépasser la densité de puissance suivante, exprimée en

W/m2 0,02619ƒ0,6834

Ainsi, le niveau maximal d’exposition permis pour la population générale et les situa-

tions d’exposition non contrôlée à 915 MHz est de 2,77 W/m2 en moyenne sur une

période de 6 minutes.

La densité de puissance des RF générées par le lecteur Encompass 4H utilisé a été cal-

culée pour un gain d’antenne maximal de 11,0 dBi, soit l’équivalent du gain de

antenne interne.

Mise en garde

Avec une puissance transmise de 0,291 W, la densité de puissance maximale calcu-

lée à 13 pouces (33 cm) de l’antenne était inférieure à 2,77 W/m2. Par mesure de

précaution, installer l’antenne à au moins 13 pouces (33 cm) de la population géné-

rale. Le personnel d’entretien doit se tenir à au moins 4.8 pouces (12,3 cm) de

l’antenne lorsque le système est en cours d’utilisation.

Les données confirment que l’utilisation de Encompass 4H utilisé répond aux

exigences de l’OSHA et ne présente pas de danger lié à son utilisation, que ce soit

pour la population générale ou le personnel d’entretien.

Figure 3-5 eGo License Plate Tag

Installing eGo Plus Sticker Tags

eGo Plus Sticker Tags are designed to be attached by a semi-permanent adhesive to

the interior surface of nonmetallic windshields 0.190 to 0.230 inches (4.82 to 5.84

mm) in thickness. For optimum performance, you must install the tag at least 2 inches

(5 cm) from the metal in the windshield frame and 0.75 inch (1.9 cm) from the rear-

view mirror support post. Detailed instructions for installing the eGo® Plus Sticker

Tag are found in the pocket guide “Quick and Easy Installation Instructions for the

eGo® Plus Sticker Tag.”

Some vehicles have a tinted area across the top of the windshield. If the tint is conduc-

tive, it can interfere with reading the tag. If a windshield has this conductive tint, the

tag must be installed at least 2 inches (5 cm) below this tinted area.

Encompass 4H Reader System Guide

3-8

Some vehicle windshields contain a metallic treatment that could prevent an interior

windshield-mounted tag from being read. However, many of these metallized wind-

shields have areas that are not metallized. On a vehicle without open areas in its met-

allized windshield, you might need to install an Encompass 4H Reader-compatible

LPT on the vehicle. See the section “Installing eGo Plus License Plate Tags” on page

3-13. Contact TransCore for more information. See the section “Technical Support”

on page 9-6.

Required Materials

Installing eGo Plus Security Sticker Tags

An eGo Plus Security Sticker Tag is located in the same area on the windshield as the

eGo Plus Sticker Tags. See “Positioning eGo Plus Sticker Tags” on page 3-8 for this

information. The eGo Plus Security Sticker Tag is slightly less flexible than the eGo

Plus Sticker Tag so the installation instructions differ. Detailed instructions for install-

ing the eGo® Plus Security Sticker Tag are found in the pocket guide “Quick and Easy

Installation Instructions for the eGo® Plus Security Sticker Tag.”

eGo Plus Security Sticker Tag Installation Procedures

Caution

Confirm that the outside temperature is above 50°F (10°C). The security sticker tag

may not adhere correctly if the temperature is below this temperature.

To install the eGo Plus Security Sticker Tag

1. Determine the tag installation location for the vehicle using the placement

guidelines in the section “Positioning eGo Plus Sticker Tags” on page 3-8.

6. Press the security sticker tag firmly against the glass. Gently rub over the entire

tag surface removing as much air from underneath the tag (Figure 3-12). The

security sticker tag’s rigid case may prevent you from forcing out all of the air

trapped between the tag and windshield. A minimal amount of air will not affect

tag performance.

Figure 3-12 Second Step of eGo Plus Security Sticker Tag Application

Removing eGo Plus Security Sticker Tags

Locate the tapered edge under the lower right corner of the eGo Plus Security Sticker

Tags and carefully pull the tag from the windshield. If you cannot lift the tag using

your fingers, insert a plastic scraper underneath the corner and lift the tag. Once you

have removed the tag from the windshield, clean any reside using isopropyl alcohol or

commercial glass cleaner. The tag is destroyed upon removal and cannot be reused.

Choosing, Installing, and Removing Tags

3-13

Installing eGo Plus License Plate Tags

Metallized coatings on some vehicle windshields and windows absorb the RF energy

emitted by the Encompass 4H Reader, thus causing tags to be misread. You must use

exterior LPTs on vehicles with metallized coatings on their windshields and windows.

Use license plate installation techniques to install tags on the exterior of vehicles that

have this type of window coating.

Note: The read zone of an overhead Encompass 4H Reader should be adjusted

accordingly when an exterior tag is installed on a license plate, or the read zone will

be reduced.

Required Materials

•Screwdriver (flat-blade or Phillips depending on the vehicle’s license plate

mounting screws)

•Optional TransCore Exterior Tag Accessory Kit (19077-01). This kit contains

tamper-resistant mounting screws and wrench.

•eGo Plus LPT

Positioning eGo Plus License Plate Tags

The eGo Plus LPT is installed over the license plate at the upper part of the vehicle’s

front license plate area.

Note: If your state does not require a front license plate, install the LPT in the area

where the license plate would normally be mounted. If your vehicle does not have a

front license plate area, contact your tag agency for other tag options.

The orientation of the tag is important. The tag must be mounted so that the holes on

the tag base plate are on the top edge.

eGo Plus LPT Installation Procedures

To mount the eGo Plus LPT

1. Remove the screws from the license plate area of your front bumper (Figure 3-

13). If your vehicle does not have mounting screws you will need two self-

tapping threaded screws. You can also contact the tag agency to inquire about the

optional TransCore Exterior Tag Accessory Kit.

Note: You may need to use longer screws to fasten the LPT over the top area of your

license plate.

Encompass 4H Reader System Guide

Figure 3-13 Correct Mounting Location for LPT

2. Position the LPT so that it is within 18 inches (46 cm) of the center of the front

bumper as shown by the shaded area in Figure 3-13. If your vehicle’s license

plate mounting area is more than 18 inches (46 cm) from the center, you may

need to select an alternate location to mount the tag. Contact your tag agency if

your vehicle requires an alternate mounting location for the LPT.

3. Hold the LPT so that the etched lettering is facing you with the mounting holes to

the top as shown in Figure 3-14.
