System Check-Out 3-37
17. Headset Installation
The system supports integrated headset operation. Customers may take advantage of
this standard system feature at any key telephone. Most headsets will operate without
extra equipment or need for additional steps in user operation.
Installation
1. A headset adapter that uses a rocker-type switch to select between Headset and
Handset use is desirable. The headset adapter is plugged directly into the Handset
jack.
2. The telephone handset is then plugged into the headset adapter.
Non-amplified headsets receive operating voltage from the headset circuitry built into
the phone. (
Refer to the headset manufacturer's instructions for information regarding
compatibility, power source, power adapter or batteries, and special options).
System Check-Out
After completing installation on the DHS-E system, it must be intitialized so that default
data can be loaded. Prior to actual power up and initialization, the DHS-E should be
checked-over to avoid startup delays or improper loading:
1. Make sure that the KSU is properly grounded.
2. Verify that all PCBs are firmly seated onto their connectors.
3. Inspect the MDF for shorted wiring and improper polarity that would affect the
Digital Key Terminals or DSS consoles.
4. Make sure that the plug-ended MDF cables connected to the KSU are secure and are
plugged into the correct position.
Power Up Sequence
The power up sequence involves the proper application of AC power to the system. A
successful power up is assured if the installation procedure has been followed:
1. Plug the AC power cord of the KSU into the dedicated 117V AC outlet.
2. Locate the database INITIALIZATION switch SW1 on the CPU Module. It is located at
the bottom edge of the CPU Module oriented in the center. It is also labeled ON and
OFF.
This switch controls connection of the dynamic RAM battery circuit. When switched
OFF, customer volatile database programming is not protected by the memory
battery in the event power is lost. In normal operation this switch will be ON at all
times.
3. To load default at this time, turn KSU power OFF.
4. Operate the INITIALIZATION (SW1) to the OFF (left) position.
On amplified headsets with self-powered (battery) headset adapters, the key telephone
MUTE operation may not mute the headset. This is because the key telephone MUTE
function removes system battery from the microphone at the handset jack. External power
supplied to the headset will maintain its microphone voltage and allow the user to override
the key telephone MUTE operation. In this case, the headset adapter MUTE function must
be used (refer to the headset manufacturer's instructions for more details).
