MAKING CALLS USING A HEADSET
• If you are in Speaker/Headset audio mode, press to switch between handsfree and headset.
• When the handset is on hook, press to disconnect the call.
NOTE: When handsfree is on, the speaker light turns on.
USING A HEADSET
The 6910 accepts analog and DHSG/EHS headsets through the modular RJ22/RJ45 port on the back of
the phone. Contact your telephone equipment retailer or distributor to purchase a compatible headset.
NOTE:
1. The RJ22/RJ45 headset port is for headset use only. Plugging any other devices into this port may
cause damage to the phone and will void your warranty.
2. Customers should read and observe all safety recommendations contained in headset operating
guides when using any headset.
VOLUME CONTROLS FOR THE HEADSET MICROPHONE
On the 6910, there are three options for the headset microphone volume: Low, Medium, and High. For
information about configuring the headset microphone volume, see “Headset Mic Volume”.
MAKING AND RECEIVING CALLS USING A HEADSET
IP PHONE UI
1. Ensure that you have selected a headset audio mode (see “Audio Mode”).
2. Turn the phone over and locate the headset jack marked f. If you have a headset with an RJ9/RJ22
4-pin connector, insert the headset cord into the jack until it clicks into place. If you have a DHSG/EHS
headset with an RJ45 6-pin or 8-pin connector, remove the plastic headset jack adapter and then
insert the cord into the jack until it clicks into place.
NOTE: See the Mitel 6910 SIP IP Phone Installation Guide for more information.
3. Press the key to obtain a dial tone or to answer an incoming call. Depending on the audio mode
selected from the Options List, a dial tone or an incoming call is received on either the headset or the
handsfree speakerphone.
4. Press the key to end the call.
REDIAL
NOTE: Redial List information in this User Guide describes the phone’s native Redial List. In some envi-
ronments, the Redial List key may bring up a Redial List provided bythe call manager; therefore,
depending on your call manager, the Redial List on your phone may function and behave differently then
what is documented in this User Guide. If this is the case, contact your System Administrator for more
information regarding your specific Redial List.
