A. Adjusting Speaker Volume
The speaker volume pot can be adjusted to
increase or decrease the speaker volume to
the level desired.
B. Adjusting the Microphone Volume
In certain noisy locations (background traffic,
machinery or wind), the microphone volume
may need to be decreased. A symptom of
this is one-way talk path, in which the distant
party cannot be heard over the speaker. A
microphone volume pot is provided for
increasing or decreasing the microphone vol-
ume. Note: If the microphone volume is set
too high or too low, one-way talk path may
occur.
C. DIP Switch Programming
1. Auto Answer Feature ON/OFF (DIP Switch 1)
DIP switch 1 is for turning the Auto Answer feature ON and OFF.
The E-65 is factory set to auto answer when an inbound call is
detected.
2. Dial Tone Detection ON/OFF (DIP Switch 2)
With DIP switch 2 in the ON position, if the E-65 detects more
than 5 seconds of continued dial tone, the unit will automatically
disconnect. If the E-65 is installed on a continuously noisy line, it
may detect the noise as dial tone and automatically disconnect. If
this happens, turn the dial tone detection (DIP switch 2) OFF.
3. Programming Mode ON/OFF (DIP Switch 3)
With DIP switch 3 in the OFF position, the E-65 is in the "Normal Operation Mode" (factory setting). By placing DIP
switch 3 in the ON position, the E-65's programming mode is enabled. The programming mode is used for adjust-
ing the Call Length Time Out, Silence Time for automatic disconnect and the Talk/Listen delay (VOX switching
speed). These features are set from the factory and normally do not need adjustment. If adjustment is necessary,
see Programming sections D - I.
4. LED On/Off (DIP Switch 4)
With DIP switch 4 in the ON postion, the blue faceplate LED will remain on at all times (to help locate push button
switch in dark locations), dim to indicate off hook and flash to indicate incoming ring. When connecting an E-65 to
a C.O.line, turn the LED off to comply with FCC regulations.
