0. Step by Step Procedure for EHS Headset to DT8xx/DT7xx/DT4xx/DT3xx

Attention: The power must be turned off to the terminal when connecting the EHS cable to the DT8xx/DT7xx/DT4xx/DT3xx.

Additional instructions (beyond what is noted below) will be provided with the headset purchase.

1. Connect the EHS cable to the microphone and indicator.

Microphone

Indicator

Microphone: Detects the ringer activation on the DT8xx/DT7xx/DT4xx/DT3xx. Upon detection, the headset provides a beep tone in the ear piece of the headset. Note: In order to enable detection, the NEC terminal must be conditioned to the appropriate ring type. Review ITL Terminals Headset Ring Tone Support and DTL Terminal headset Ring Tone Support for configuration assignments.

Indicator:    This provides an indication to the user that the headset is in use

2. Connect the EHS cable to the DT8xx/DT7xx/DT4xx/DT3xx Slot 1

Insert the EHS cable to side option connector (SIDE 1) and the headset module to the headset jack.

ATTENTION: Special attention should be given when connecting the EHS cable to side 1 of the terminal. The connector has groves that will allow the connector to fit easily into the port. Don’t jam (push) the connector in the port otherwise the connector will break.

3. Paste the microphone to the DT8xx/DT7xx/DT4xx/DT3xx

4. Connect the EHS Cable to the Headset base

5. Turn on the DT8xx/DT7xx/DT4xx/DT3xx and Headset Base unit

0. Procedure for Enabling EHS function on the UNIVERGE Switch

ATTENTION: EHS function can only be enabled when the headset function is assigned as a feature key.

1. SV8xxx switch environments require a specific key assignment for the headset feature key.
2. SV9xxx switch allow flexible location assignment for the headset feature key.

Programming for the headset key is detailed in the NEC switch programming manual.

-    Assign a headset feature key to the terminal in Function keys
