IMPORTANT USER SAFETY INSTRUCTIONS

The most careful attention has been devoted to quality standards in the manufacture of your new telephone. Safety is a major factor in the design of every set. But, safety is YOUR responsibility too.
Please read carefully the helpful tips listed below and on the next page. These suggestions will enable you to take full advantage of your new voice terminal.
Then, retain these tips for later use.
CAUTION:
This telephone is NOT for residential use. It is for business systems applications ONLY. It will NOT operate on public networks. It MUST BE connected to a DEFINITY Enterprise Communications Server.
Use in a residential environment could result in an electrical short circuit when the telephone wiring is set up to provide other applications, for example, for appliance control or power transformers. The AC power used in these  applications may create a safety hazard by placing a direct short circuit across the telephone wiring.

Use
When using your telephone equipment, the following safety precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons.

  • Read and understand all instructions.

  • Follow all warnings and instructions marked on the telephone.

  • This telephone can be hazardous if immersed in water. To avoid the possibility of electric shock, do not use it while you are wet. If you accidentally drop the telephone into water, do not retrieve it until you have first unplugged the  line cord from the modular wall jack. Then, call service personnel to ask about a replacement.

  • Avoid using the telephone during electrical storms in your immediate area.
    There is a risk of electric shock from lightning. Urgent calls should be brief. Even though protective measures may have been installed to limit electrical surges from entering your business, absolute protection from lightning is  impossible.

  • If you suspect a natural gas leak, report it immediately, but use a telephone away from the area in question. The telephone’s electrical contacts could generate a tiny spark. While unlikely, it is possible that this spark could ignite  heavy concentrations of gas.

  • Never push objects of any kind into the equipment through housing slots since they may touch hazardous voltage points or short out parts that could result in a risk of electric shock. Never spill liquid of any kind on the telephone. If  liquid is spilled, however, refer servicing to proper service personnel.

  • To reduce the risk of electric shock, do not disassemble this telephone.
    There are no user serviceable parts. Opening or removing covers may expose you to hazardous voltages. Incorrect reassembly can cause electric shock when the telephone is subsequently used.

Service

  1. Before cleaning, unplug the telephone from the modular wall jack. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
  2. Unplug the telephone from the modular wall jack. Be sure to refer servicing to qualified service personnel when these conditions exist:
    — If liquid has been spilled into the telephone.
    — If the telephone has been exposed to rain or water.
    — If the telephone has been dropped or the housing has been damaged.
    — If you note a distinct change in the performance of the telephone.

Headsets

On all of the 6400 Series telephones except the 6416D+M and 6424D+M, the headset connection consists of a headpiece (shown as 1 in Figure 2 below)
and modular base unit (shown as 2 in Figure 2). In this instance, the base unit plugs into the Handset jack (shown as 3 in Figure 2).

FIGURE 2 The Headset Attached to the Handset Jack on a 6400 Series Telephone (via a Modular Base Unit)
On the 6416D+M and 6424D+M sets, there is a jack provided for ONLY the headset. In Figure 3, the headset is shown as 1; the Headset jack is shown as 2. On these sets, the headset can either be connected, with an adapter cord (shown  as 3 in Figure 3), to the Headset jack on the back of the telephone or connected to a modular base unit which then plugs into the Headset jack.

Note: When a modular base unit is used with the Headset jack, the handset should remain plugged into the Handset jack.
The privacy of the Whisper Page announcement cannot be guaranteed when telephones have modular base units other than the M10L-8400 (Comcode: 407639715; PEC: 3122-022). The M10L-8400 is the only modular base unit that should be used for the 6400 Series telephones.
Note that this does NOT apply to headsets plugged into the Headset jack on the back of the 6416D+M and 6424D+M telephones that do not require a modular base. For more information, see the instructions for the Whisper Page feature  in the Voice Features section.
Note: If you plug the headset directly into the Headset jack, you may use a button on the adapter cord, if so equipped, to go off-hook and on-hook, or a button may be administered.
