Learning about Your Phone
The phone turns itself off.
Far-field Speaker
Press the Far-field Speaker ( ) key to turn on the far-field speaker (see “Keys” on
page 8). The far-field speaker allows you to hear a call without holding the phone to your
ear (like a speakerphone). The far-field speaker is for listening to calls only; you must use
the microphone to talk.
Depending on how your phone is configured (see “Viewing Access Control Settings” on
page 22), you may not be allowed to use this feature during secure calls.
Miscellaneous Information
The following information may be useful for understanding the operation and
characteristics of your phone.
Interoperability with Other FNBDT Equipment
For secure calls, your QSec-2700 phone is designed to operate with other currently
available FNBDT-compliant secure telephones. This includes QSec-800 phones, FNBDT-
STE, Sectera Wireline Terminal (SWT), Sectera GSM phone and Omni. Contact your
Terminal Administrator for a list of interoperable equipment.
Secure Voice Call Characteristics
Secure voice calls do not sound the same as clear voice calls. Voice quality may be better
in clear calls, and the transmission time may be significantly shorter in clear calls. When
engaged in a secure call, try not to interrupt the other party; speak clearly and allow for
longer pauses between your voice and their voice.
Note
Certain features (such as secure-to-clear and clear-to-secure transitions) only
work with other QSec phones, as these features may not be available with other
brands of secure phones.
