WJ-NT204 OPERATING PROCEDURES
This section details about operations made in the control
site where a WJ-NT204 Network Interface Unit is installed
as a receiver. For control site operations with WWW brows-
er, refer to MAIN PAGE AND CONTROLS on page 70.
Before Operating the Unit
Confirm the following.
1. The relevant peripherals are connected to the unit in
the site, and they are turned on the power.
2. A Remote Controller is connected to the unit. It oper-
ates major functions in the system.
3. System setups and call directory registrations are com-
pleted to the Network Interface Unit.
4. Turn on the power switch of the unit. The power indica-
tor illuminates, and the monitor displays the initial
screen shown on the right column.
5. The supplied Power Switch Protector is put on the
power switch.
About Power ON/OFF
Please use caution to the power operation.
Caution:
The power switch does not have a sufficient insulation
capability from the AC mains even when it is turned off.
We recommend that you unplug either end of the
power cord from the unit or the AC outlet when you do
not use the unit for a long time. Turning off the AC cir-
cuit breaker will be another cut-off measure if the unit is
connected to it.
Note:
• Do not turn off the power switch while the unit is in
communication.
• After the unit has been turned off or unplugged for a
long time, supply AC power to the unit and turn it on to
charge up the backup battery.
