Paging the base unit from the portable handset
The portable handset user:
Press the INTVPAGE button.
—Both units beep while the
INTVPAGE button is pressed.
When you release the button, the
unit automatically switches to the
intercom mode. If there is no
answer, press the INTVPAGE
button again to end the intercom.
The base unit user:
When the unit beeps and the paging
party’s voice is heard, answer
through the MIC.
The portable handset user:
When the conversation is over, press
the INTVPAGE button.
—Intercom calls can only be
terminated by the portable handset.
Helpful hints:
—Even while in a conversation with an outside caller, the portable
handset user can page the base unit user by pressing the
INTVPAGE button. The outside call is put on hold then. To return to
the outside call, press the TALK button.
—If you hear two tones while using the intercom feature, it means
someone is calling from outside. These two tones replace the normal
ringing signal. You can answer the call by pressing the TALK button.
The intercom call is then terminated.
