Viking E-50-BK Technical Practice page 7

D. Accessing the Programming Mode
The E-50 can be programmed from any Touch Tone phone using a telephone line, Viking model C-200, C-250 or C-
2000B 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-50.
Step 4. When the E-50 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
Call length time out (1-9 minutes), 10 = disabled (factory set to 11111 = 5 minutes) .......................................
Silence time out for disconnect (10-90 seconds), 10 = disabled (factory set to 1111 = 40 secs) .....................
Talk/listen delay (VOX switching speed) 0.1 - 0.9 seconds (factory set to 111 = 0.3 secs) .............................
Forced hang-up command (used to exit programming and hang up the E-50) ..............................................
F. Programming Beeps
If a valid "Feature" is entered, a single beep will be heard and you will have 20 seconds to enter a "Time" value. If an
invalid "Feature" (five or more zeros) or forced hang-up command (four zeros) is entered, 3 beeps will be heard and
the E-50 will hang up. If a valid "Time" is entered 2 beeps will be heard and you will have 20 seconds to enter your
next "Feature". If an invalid "Talk/Listen Delay Time" is entered (10 or more ones), 3 beeps will be heard and you will
have 20 seconds to enter your next "Feature".
G. Call Length Time Out
This feature selects the maximum length of time that calls can be con-
nected. Programmable in increments of 1 minute up to a maximum of
9 minutes. To disable the call length time out, program ten ones in the
"Time" value location. With the call length disabled, the E-50 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.
H. Silence Time Out
This feature selects the length of time that calls will remain connected without voice activity. Programmable in incre-
ments of 10 seconds up to a maximum of 90 seconds. To disable the silence time out, program ten ones in the "Time"
value location. Use the chart at the right. * Note: The factory default is 40 seconds.
I. Talk/Listen Delay (VOX Switching Speed)
This feature selects switching time between talk and listen modes (VOX switching time). Use the chart above.
* Note: The factory default is .3 seconds.

When the push button is pressed, the E-50 phone goes off-hook, much like a standard speaker phone. In the event that
the line is busy, the E-50 will hang-up. The E-50 will also automatically hang up on CPC, silence, busy signal, return to dial
tone or time out. If programmed to auto-answer (DIP switch 1 ON), the E-50 will also answer any incoming call.
The E-50 color video camera operates completely independently of the E-50 phone board. With power supplied to the cam-
era, it will continuously output a video signal.
