A. Adjusting the Speaker Volume
The SPKR VOL pot can be adjusted to increase or de-
crease the speaker volume to the level desired as shown.
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 MIC VOL pot is provided for increasing or de-
creasing the microphone volume. Note: If the microphone volume
is set too high or too low, one-way talk path may occur.
* Note: To increase surge protection, loosen the PCB mounting screw labeled
shown) and fasten a wire with spade terminal (included) from the mounting screw to Earth Ground (grounding rod, water pipe, etc.)
C. DIP Switch Programming
1. Auto Answer Feature (DIP Switch 1)
DIP switch 1 is for turning the Auto Answer feature ON and OFF.
The E-10/E-20 is factory set to auto answer when an inbound call
is detected.
2. Dial Tone Detection (DIP Switch 2)
With DIP switch 2 in the ON position, if the E-10/E-20 detects more
than 5 seconds of continued dial tone, the unit will automatically dis-
connect. If the E-10/E-20 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 (DIP Switch 3)
With DIP switch 3 in the OFF position, the E-10/E-20 is in the "Normal Operation Mode" (factory setting). By placing DIP switch
3 in the ON position, the E-10/E-20'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.
The E-10/E-20 can be programmed from any Touch Tone phone using a telephone line, Viking model C-200 or
C-2000A Entry Phone Controller, analog PABX/KSU station or a Viking model DLE-200B Line Simulator.
Step 1. Move DIP switch 1 to the ON position (sets unit to answer incoming calls - see section C).
Step 2. Move DIP switch 3 to ON (incoming calls automatically enter the programming mode - see section C).
Step 3. From a Touch Tone phone call the line attached to the E-10/E-20.
Step 4. When the E-10/E-20 answers, 2 beeps will be heard and you will automatically enter the programming mode.
Step 5. When finished programming, enter "0000" to exit programming and move DIP switch 3 back to OFF (see section C).
E. Quick Programming Features
Description
Call length time out (1-9 minutes), 10 = disabled (factory set to 11111 = 5 minutes) ...................................... 0
Silence time out for disconnect (10-90 seconds), 10 = disabled (factory set to 1111 = 40 secs) ................... 00
Talk/listen delay (VOX switching speed) 0.1 - 0.9 seconds (factory set to 111 = 0.3 secs) ............................ 000
Forced hang-up command (used to exit programming and hang up) ............................................................ 0000
F. Programming Beeps
If a valid "Feature" is entered, a single beep will be heard. If an
invalid "Feature" (five or more zeros) is entered, 3 beeps will be
heard and the E-10/E-20 will hang up. If a valid "Time" is en-
tered 2 beeps will be heard. If an invalid "Time" is entered, 3
beeps will be heard and you will have 20 seconds to enter the
next valid "Feature".
G. Call Length Time Out
This feature selects the maximum length of time that calls can
be connected. Programmable in increments of 1 minute up to
a maximum of 9 minutes. Programming nothing in the time
value location will disable the call length time out. With the call
length disabled, the E-10/E-20 phone must rely on CPC, busy,
silence or return dial tone to hang-up. Use the chart at the right.
* Note: The factory default is 5 minutes.
