H. Repositioning the Camera when Mounting the E-50 Horizontal
(Requires Viking model LB-50 Camera L-Bracket - not included with the E-50)
When mounting the E-50 to 4 inch or less horizontal lap siding, the unit can be mounted horizontally. When doing so, the internal
video camera will have to be repositioned (vertically rotated 90 degrees) to correct the video image orientation. An additional cam-
era "L" bracket (Viking model LB-50) is required to reposition the camera. To purchase LB-50 contact your local Viking distributor.
To install the LB-50, remove the bottom #2 screw and lock washer which fastens the camera "U" bracket to the circuit board mount-
ing plate. Remove the two screws mounting the camera to the "U" bracket. Rotate the camera 180 degrees so the video output wires
exit the lower back plate of the camera and refasten it to the "U" bracket. Use the #2 screw and lock washer to attach the LB-50 "L"
bracket to the mounting plate then attach the camera to the "L" bracket with the screw and lock washer supplied with the LB-50 as
shown in the diagram. Note: Mounting the E-50 horizontally will reduce the camera horizontal adjustment to +/- 20 degrees and
increase the vertical tilt to +/- 30 degrees.
* Caution: When mounting the camera horizontally on a model E-50-EWP, the single gang rough in box may require trimming to
allow room for the new camera position.

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 dis-
tant party cannot be heard over the speaker. A micro-
phone volume pot is provided for increasing or decreasing
the microphone volume. 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-50 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-50 detects more than 5
seconds of continued dial tone, the unit will automatically disconnect. If
the E-50 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-50 is in the "Normal Operation Mode" (factory setting). By placing DIP switch 3 in
the ON position, the E-50's programming mode is enabled. The programming mode is used for adjusting 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-50 to a C.O.line, turn the LED off
to comply with FCC regulations.
