Packing and unpacking
Use proper care when unpacking any add-on module. Check for damaged
containers so that appropriate claims can be made to the transport company
for items damaged in transit.
If a module must be returned to the factory, pack it in the appropriate
container to avoid damage during transit. Remember to include all loose parts
in the shipment.
There are three distinct versions of Meridian Modular Telephones – all three
are supported. The versions can be clearly distinguished by the first four
letters in the upper left-hand corner of the model identification label on the
bottom of the telephone.
The three versions are as follows:
• the “NTZK” models
• the “NT2K” models with date code prior to April 24, 1998
• the third version includes both the “NT9K” models and the “NT2K”
models with date code of April 24, 1998 and later
In addition, the two jacks face in the same direction on “NT2K” and
“NT9K” telephones, and in opposite directions on “NTZK” telephones.
When appropriate, differences between the models are noted in this
document.
