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:

24V DC rating: 24V ±10%, ≤ 90mA
12V DC rating: 12V ±10%, ≤ 170mA

■ 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.

Connector

•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: CX-SAC0SAD0Q0750)
(OKI) for extension decreases transmission distance.

■ 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.

•Use a shielded twisted pair (STP) cable as a LAN cable.

■ 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.
