Dterm Headset Cordless II (P/N 730091)
The Dterm Headset Cordless II is a cordless headset telephone. It is basically a single-line tele-
phone, but it has no dial, so it does not provide all of the functions of a single-line telephone. As
such, it generally would not be connected directly to a telephone line or an analog station port. It is
speci
Þ
cally designed to interface with an Aspire 22/34-button keyset equipped with an APA or APR
Adapter.
The number of units which can be used on the system can range from 15-50. The maximum number
is greatly affected by the environment. The closer or smaller the area, the smaller the number of
units which can be used. The Dterm Headset Cordless II uses frequency hopping to automatically
change channels if interference is present. If the unit detects wideband interference (multiple users
in a small area), the range will be decreased until an adequate link is formed. The present of other
900 MHz devices will cause interference and may need to be removed.
The Dterm Headset Cordless II features include:
●
8 hours of talk time

Up to 300’ roaming distance from an of
