RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK, 
DO NOT REMOVE COVER (OR BACK). NO USER 
SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.

This symbol warns the user that uninsulated voltage within 
the unit may have sufficient magnitude to cause electric 
shock. Therefore, it is dangerous to make any kind of contact 
with any inside part of this unit.

This symbol alerts the user that important literature concerning 
the operation and maintenance of this has been included.
Therefore,  it  should  be  read  carefully  in  order  to avoid 
any problems.

T

here are special components used in this equipment which are important for safety. These parts are indicated 

by the ”

 

Y

 

” mark on the schematic diagram and the replacement parts list. It is essential that these critical 

parts should be replaced with manufacturer's specified parts to prevent X-radiation, shock, fire, or other hazards.

Do not modify the original design without permission of manufacture.

PCBs (manufactured) using lead free solder (PbF) will have a stamp on the PCB.

For priority announcement, this indicator lights up dur-
ing public address is performed through other remote
control microphones. However, when the individual pri-
ority function is active, the indicators of higher priority
microphones do not light up during public address is
performed through a lower priority microphone.

e

Lights up during public address is performed with this
unit.

r

Lights up during 24 V DC is supplied to this unit.

t

When announcing an audio program from the device
connected to the line input, press this switch. 

y

When making an announcement to all blocks in unison
from this unit, press this switch. It is not necessary to
press the announcement switch to make an announce-
ment in unison.

T

Makes the device connected to this unit (an emergency
public address system or a business public address
system) sound a call sign.

Do not press the call sign up and down switches

simultaneously. Failure to observe this activates the
status of an announcement in unison.

i

When making an announcement with this unit, press
this switch. If you press this switch again, the
announcement will be finished.

o

When making an announcement through the flexible
microphone, press this switch.

When making an announcement to a specific block,
press the corresponding switch.
