This Manual and the Markings on the product contain various symbols
in order that the product can be used safely and property, and that the
installer and user are protected from injury and property damage. The
following precautions must be thoroughly read and understood before
proceeding.
PRECAUTIONS ON INSTALLATION & WIRING
A\ WARNING Negligence could result in death or serious injury.
/K CAUTION Negligence could result In injury or damage to property.
1. Do not connect any power source other than
specified on NEM master. Fire or damage to
the unit could result.
2. Do not open NEM master. High voltage Is
present inside, and it can cause electric shock.
3. Do not change or alter NEM master. It can
cause fire or electric shock.
4. Make sure wires are connected properly before
plugging in power supply.
5. Keep NEM master away from water or any other^
liquid. Fire or electric shock could result.
6. Keep AC plug away from moisture or dust.
7. Keep AC cord away from being marred or
crushed.
8. Do not plug or unplug with wet hands.
9. Do not put any metal into NEM through openings,
It can cause fire, electric shock or unit damage?
CAUTION
A
. Do not make call tone testing with hook switch
manually held down. The call tone sounds very
loud near your ears, and can cause your hearing
damage.
. Do not install or make any wire terminations while
power supply is plugged in. It can cause electrical
shock or damage to the unit.

3. Install NEM master in a convenient location, but ^
not where it could be bumped or jarred. V
4. In case of electrical storms, unplug power supply
from AC outlet. It can cause fire, electric shock,
or power surge damage.
5. Do not install NEM components in any of the
following locations, as it may cause the system to
malfunction;
- High or extreme cold temperature area:
under direct sunlight, near equipment that varies in
temperature, in front of air conditioner, inside a
refrigerated area, etc.
- Places subject to moisture or humidity extremes. I
- Places subject to environmental conditions,
such as oil, dust, chemicals, salt, etc.
- Places subject to constant vibration or impact.
- Places where noise generating devices such as
TV or radio are close by.
GENERAL PRECAUTIONS
A
1. NEM equipment is designed for indoor use only.
Do not install outdoors.
2. NEM system is not operational during a power failure.
3. In areas where broadcasting station antennas are close
by, intercom system may be affected by radio frequency
interference.
4. Keep ail DC wiring at least 30cm, 1' away from AC 100240V wiring, fluorescent lighting, or dimmer switches.
Otherwise, cross AC wiring at a 90° angle.

SYSTEM COMPOSITION
The NEM-n/C & NEM-nA/C can be composed into the following systems with the optional accessories.
NEM intercom communication
Health care communication
Call switching device
Dual master call
Music distribution to NA subsNB-U adaptor distributes background music to NA subs
COMMUNICATION
After depressing a sub selector button, depress TALK switch to transmit or release to listen. On NEM-A/C
only, lift handset and communicaiton will be automatic activation. Speak into the handset, and NEM transmits
voice. Quit speaking, and NEM turns to receive mode.
STATION SELECTION
1. Sub station: NA-T/A handset can be used alone or attached the other sub station.
2. NEW-5 dual call adaptor Is not useable with in NB-U used system.
System consists of NEM master and sub stations as needed.
Each sub station is connected with a corridor call light & reset
button. Ceiling sub NB-L is combined with bedside call switch.
Any sub's call-in received by one NEM, can be rotated
to the other NEM on duty.
NEW-5 adpator enables up to 5 sub stations to ring two
NEM's simultaneously, install multiply NEW-5's with
a 12V DC power supply.
in conjunction with music source & an appropriate amplifier.
POWER SUPPLY
WIRING METHODS
Lay out your NEM system in advance. Determine the locations of each NA sub station and wire to each.
Two conductors are required per sub station.
1. Two wires from each sub station to NEM terminal block.
2. Two wires from each sub to a local junction box, then multi-conductor cable to NEM teminai block.
3. Use a multi-conductor cable looped through each sub.
IMPORTANT: When a multi-conductor cable is not used, be sure to run each cable in the same conduit,
in order to make each sub station line as near the common line as possible.

MOUNTING LOCATIONS
1. Select a mounting location which meets the following criteria:
- is free from dust, vibration, - is not near heating or air conditioning equipment,
- does not have temperature/humidity extremes, - run in not bare wires on floor subject to
be pinched by furniture, etc., - is not near inflammable or chemical products.
NONE OF THE SYSTEM COMPONENTS IS EXPLOSION-PROOF TYPE.
2. NBR-7AS bathroom pullcord is moisture-resistant, but not water-resistant.
Avoid such location as near bathtub, etc. where it could receive shower directly.
3. NA-NE is not weather-resistant. Do not install outdoors.

Operating temperatures
NEM & NEM-A master stations are rated to operate
at temperatures between 0° ~ 40°C (32 °F ~ 104°F).
Mounting iocations
The NEM equipment is not explosion proof type. Do
not install any unit In a place filled with Igniting gas.
Operation
At end of every communication, be sure to depress
corresponding OFF button, which disconnects the
sub station as well as puts system in standby.
Otherwise, call tone will not sound audibly.
When asking for repairs
When system malfunctions, do not attempt to remove
or change any unit. Call the installing dealer or
representative.
Cleaning
Clean NEM equipment with a soft cloth dampened
