BEFORE USE ....

Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.

■ PACKAGE INCLUDES:

Wireless gateway.................................................................(1)

Antenna ...............................................................................(1)

Terminating resistor (110Ω, 0.25W) ...................................(1)

■ MODEL NO.

Confirm Model No. marking on the product to be exactly
what you ordered.

■ OPERATING MANUAL

This manual describes necessary points of caution when
you use this product, including installation, connection,
hardware setting, and basic maintenance procedures.
For information on the introduction of wireless device, refer
to the 900MHz band wireless device operating manual (EM­XXXX-B).

•Attachment of rooftop antenna; There is a magnet on the
bottom face which allows you to attach the antenna on
a metal box and such. To obtain optimum performance
from the antenna, attach on a metal plate (recommended
dimension: 500 mm × 500 mm or more). However, in the
case of connecting FE1 to a metal plate, the isolation be­tween FE1 and antenna connector will be lost. Tighten
the connector with a specified torque (0.9 N∙m). As a
guide, finger-tighten it until the connector stops, and then
rotate it 10 to 15 degrees with a wrench. Do not force the
cable to bend less than acceptable radius of 3 cm.

•Using 7.5 m coaxial cable (model: xxx)(OKI) for extension
decreases transmission distance.

POINTS OF CAUTION

■ POWER INPUT RATING & OPERATIONAL RANGE

•Locate the power input rating marked on the product and
confirm its operational range as indicated below:

24 V DC rating: 24 V ±10%, ≤ 70 mA
12 V DC rating: 12 V ±10%, ≤ 130 mA

■ GENERAL PRECAUTIONS

•Before you remove the unit or mount it, turn off the power
supply for safety.

■ ENVIRONMENT

•Indoor use.

•When heavy dust or metal particles are present in the

air, install the unit inside proper housing with sufficient
ventilation.

•Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.

•Environmental temperature must be within -20 to +60°C
(-4 to 140°F) with relative humidity within 10 to 90% RH
in order to ensure adequate life span and operation.

•Attach the antenna to the unit.

•Attachment and adjustment of sleeve antenna; Loosen

the connector (See the top-right figure.), and rotate the
antenna. Holding the antenna vertical, tighten the con­nector by hand. Make sure to fix the antenna firmly.

■ WIRING

•Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).

•Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

■ AND ....

•The unit is designed to function as soon as power is sup­plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

CAUTION REGARDING RADIO FREQUENCY

■ FCC NOTICE

•This device complies with 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.

■ FCC CAUTION

•Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s au­thority to operate the equipment.

■ NOTE

•This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accord­ance with the instruction manual, may cause harmful
interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful
interference in which case the user will be required to cor­rect the interference at his own expense.

•This transmitter must not be co-located or operated in
conjunction with any other antenna or transmitter.
