1.2 For Your Safety
•
Proper earthing (connection to earth) is very important to reduce the risk to the user of electrocution or to
protect the PBX from the bad effects of external noise in the case of a lightning strike.
•
The earthing wire of the AC cable has an effect against external noise and lightning strikes, but it may not
be enough to protect the PBX and to ensure electromagnetic compatibility. A permanent connection
between earth and the earth terminal of the PBX must be made.
•
Make sure that the AC outlet is properly earthed, then securely connect the 3-pin AC plug including the
earthed pin.
•
When installing or removing the optional service cards, do not put pressure on any parts of the mother
board. Doing so may result in damage to the PBX.
•
Once you have started the PBX, if you unplug the PBX, do not initialise it again as described in "System
Initialisation Procedure". Otherwise, your programmed data will be cleared.
•
When opening the top cover, the power switch must be turned off.
•
For safety reasons, close the top cover and tighten the screws before operating the PBX.
•
For earthing wire, green-and-yellow insulation is required, and the cross-sectional area of the conductor
must be more than 0.75 mm
•
Use only the AC power cord included with the PBX.
•
Before touching the product (PBX, cards, etc.), discharge static electricity by touching ground or wearing
an earthing strap. Failure to do so may cause the PBX to malfunction due to static electricity.
•
When installing or removing the optional service cards, the power switch must be turned off.
•
The power supply cord is used as the main disconnect device. Ensure that the AC outlet is located near
the equipment and is easily accessible.
•
To the Administrator or Installer regarding the system password
1.
Please provide all system passwords to the customer.
2.
To avoid unauthorised access and possible abuse of the PBX, keep the passwords secret, and inform
the customer of the importance of the passwords, and the possible dangers if they become known to
others.
3.
The PBX has default passwords preset. For security, change these passwords the first time that you
programme the PBX.
4.
Change the passwords periodically.
5.
It is strongly recommended that passwords of 10 numbers or characters be used for maximum
protection against unauthorised access. For a list of numbers and characters that can be used in system
passwords, refer to "1.1.3 Entering Characters" in the PC Programming Manual.
