2.2.4 Installation of the SD Memory Card
CAUTION
 Use only the SD Memory Card included with the PBX.
 The SD Memory Card contains software for all the processes of the PBX and all the customer data. 
The SD Memory Card must be inserted before startup.
 Do not remove the SD Memory Card while power is supplied to the PBX. Doing so may cause the 
PBX to fail to start when you try to restar t the system.
 To prevent data leakage, render the SD Memory Card physically unusable before disposal.
Note

2.2.5 Frame Ground Connection
IMPORTANT
Connect the frame of the PBX to ground.
 Be sure to comply with applicable local regulations (e.g., laws, guidelines).
 Proper grounding (connection to ground) is very important to protect the PBX from the bad effects of 
external noise or to reduce the risk to the user of electrocution in the case of a lightning strike.
 The ground wire of the AC cable has an effect against external noise and lightning strikes, but it may 
not be enough to protect the PBX. A permanent connection between ground and the ground terminal 
of the PBX must be made.
In most of the continental United States, the ground provided by the Third wire ground at the commercial 
power outlet will be satisfactory. However, in a small percentage of cases this ground may be installed 
incorrectly. Therefore, the following test procedure should be performed.
Test Procedure
1.Obtain a suitable voltmeter and set it for a possible reading of up to 250 V AC.
2.Connect the meter probes between the 2 main AC voltage points on the wall outlet. The reading 
obtained should be 108 V AC to 132 V AC.
3.Move one of the meter probes to the 3rd prong terminal (GND).
Either the same reading or a reading of 0 volt should be obtained.
4.If a reading of 0 volt at one terminal and a reading of 108 V AC to 132 V AC at the other terminal 
is not obtained, the outlet is not properly grounded.
This condition should be corrected by a qualified electrician (per article 250 of the National 
Electrical Code).
5.If a reading of 0 volt at one terminal and a reading of 108 V AC to 132 V AC at the other terminal 
is obtained, then set the meter to the OHMS/RX1 scale, place one probe at the GND Terminal 
and the other probe at the terminal which gave a reading of 0 volt.
A reading of less than 1 ohm should be obtained. If the reading is not obtained, the outlet is not 
adequately grounded. See qualified electrician.
1.Loosen the screw.
2.Insert a grounding wire (user-supplied)*.
3.Tighten the screw.
4.Connect the grounding wire to ground.
* For grounding wire, green-and-yellow insulation is required, and the cross-sectional area of the 
conductor must be more than 0.75 mm
2 or 18 AWG.

Note
When installing or removing the optional service cards, the power switch of the PBX must be in the off 
position.
Installing Optional Service Cards
1.Before installing the optional service cards, cut and remove the appropriate dummy cover plates from 
the main unit.
CAUTION
For safety reasons, smooth the cut edges after removing the dummy cover plates.
2.Position the card in the open slot, making sure that the tabs on the both sides of the card fit into place. 
Then, holding the card firmly in place, lower the rear end so that the hole of the card fits over the 
extension bolt.
CAUTION
When installing the optional service cards, do not put pressure on any parts of the main board. Doing 
so may result in damage.
