BEFORE YOU INSTALL AND OPERATE THE EQUIPMENT

— Prohibitions and precautions —

*Ope ration;

On all LAF master stations, except station initiating a call, OFF button MUST

BE DEPRESSED and LOCKED DOWN, or system will not work. The illumi

nated LED above OFF button indicates you forget to depress OFF button, if

not in use.

2. The illuminated OCCUPIED LED indicates the other station is using the sys

tem. While this OCCUPIED LED is lit,

(1) Do not depress any selector button. The squeak sound will come out at

initiating and receiving stations.

So, when you receive calls from another master and a sub at the same

time, REPLY FIRST TO THE MASTER and, after the OCCUPIED LED

goes out, depress a selector button of the calling sub and communicate.

(2) Do not make All Call nor any other operation, when LAF-B units are

intermixed with existing models (LAF-3A/5/10/10S/10B/I0BS).

3. When a sub station calls during Background music distribution, the call tone

will come out through all LAF station speakers, and call-in annunciator LED

stays lit for approximately 20 seconds on the called master station.

* Installation;

1. DO NOT CONNECT ANY TERMINAL ON .4NY UNIT TO AC POWER

LINES.

2. Be sure not to plug power supply into AC receptacle until you complete

wiring connections, and unplug before opening the unit.

3. Lay out your system in advance. Determine the exact location of each station.

Assign station number and make a sketch showing the number of wires and
color codes from one station to another. Begin your installation with master
station No. 1. Upon installing second master station, we recommend a test be
made for ail functions, calling and talking between each station.
After completing all the masters connection and testing, begin sub station

installation.

4. Insulate by tape, etc. each unused connector wire end. If touches the other

wires or back box it will cause damage to the units.

Installation location;

5. Select the installation locations that would not be exposed to temperature/

humidity extremes, water, oil, dust, iron dust, inflammable and chemical
products, etc.

6. To avoid feedback, DO NOT PLACE MASTER STATION AND ANOTHER

MASTER OR SUB STATION BACK TO BACK, OR ON A COMMON WALL
BETWEEN ROOMS.
