B. Volume Adjustments
C. Auto-Answer Feature
(DIP Switch 7)
With DIP switch 7 in the “ ON ” position (default), the K-1705-3 will automatically answer the line during the first incom-
ing ring. This feature is useful for monitoring entrances. In the “ OFF ” position, the K-1705-3 will not automatically
answer incoming calls.
Certain noisy locations (background traffic,
machinery or wind) may cause one way talk path
(only microphone audio is heard). In this case,
the microphone volume may need to be
decreased as shown.
D. Push Button Hang Up
(DIP Switch 8)
With DIP switch 8 in the “ ON ” position (default), the “Call ” button alternately connects and disconnects calls. In the
“ OFF ” position, the “ Call ” button is only used to connect and the K-1705-3 must rely on call progress (busy, return to
dial tone, silence time-out, or maximum call time) for an automatic disconnect.
With DIP switch 4 in the “ OFF ” position (default), the VOX switching speed (delay time between talk and listen mode)
is set to fast (0.2 seconds). In the “ ON ” position, it is set to slow (0.7 seconds).
E. VOX (Talk/Listen) Switching Speed
(DIP Switch 4)
The K-1705-3 will output 3 beeps and automatically hang-up after detecting any of the following: busy signal (standard
or fast/reorder), CPC (short break in line current when called party hangs up), return to dial tone, maximum call time
or silence time out.

When the push button is pressed, the K-1705-3 phone goes off-hook, much like a standard speaker phone. The keypad
may then be used to dial any number. In the event that the line is busy, the K-1705-3 will hang-up. The K-1705-3 will also
automatically hang up on CPC, silence, busy signal, return to dial tone or time out. If programmed to auto-answer (DIP
switch 7
ON ), the K-1705-3 will also answer any incoming call.
The K-1705-3 color video camera operates completely independently of the K-1705-3 phone board. With power supplied
to the camera, it will continuously output a video signal.
