shine or in the environment of flammable or caustic gas.) Special telephone wire is
preferable.
A wall bore is available at the underside of mainframe for wall installation. Desk installation
is also admitted. But the contact of wall bolt and circuit board inside the mainframe should
be avoided.
None of the wiring of any extension should share the pipeline with power supply or antenna.
Neither should the extension be close to antenna for air broadcasting (including
short-wave).
For the sake of personal safety and communication quality, grounding of PABX should be
reliable. Or else, the lightning-proof device inside would fail to work.
Resistance to ground should be less than 10 ohm.
Grounding as follows:
Connect the monomer-crystal with EXT. line and C.O. line separately, use the normal
telephone to test the C.O.line if is ok.
Connecting extensions according to the in-dilated extension positions and C.O. lines to the
corresponding line ports on the unit.
Test the function of power failure transfer. Before power on, off hook the extension to test if
the telephone can dial out and check the wire again if can not dial.
Connected all the wires, take the power on and to see if the indicator light twinkling, if yes
that mean the system working.
Test the system according to the default settings.
Test the whole system to see if can be worked well, if not and then reset the system.
