E. Security Bypass Mode
This mode is useful if you have forgotten your security code and need to enter programming, but requires you to be at
the physical location of the RAD-AMP.
Step 1. To enter this mode, call into the RAD-AMP.
Step 2. When it answers, slide the front panel switch to "OFF."
Step 3. Then dial ✱. Two beeps will be heard.
Step 4. Enter you new security code (6 digits + #47).
Step 5. Enter any other programming desired.
Step 6. When finished, hang-up.
Step 7. Slide the front panel switch to "ON."
F. Auxiliary Dry Contact Closure
The RAD-AMP can provide an auxiliary dry contact closure for systems that require it. To utilize this feature, an inter-
nal shunt must be set to the correct position. Important: Electronic components are sensitive to static electricity.
Personnel and the work area should be grounded before handling.
Step 1. Disconnect the power and telco cables.
Step 2. Remove the two screws on the bottom of the chassis and take off the cover.
Step 3. Locate and configure DIP switch 1 and 2 as shown in the chart below.
Step 4. Follow the instructions as shown in Installation section C.

When configured as a Line Extender, the RAD-AMP allows remote access to a loop start C.O. line, an analog PABX sta-
tion or any other 600 ohm audio device. This is useful for many applications including access to inexpensive WATS lines
(line extending), remote access to PABX/KSU features (DISA), or remote service observing using Viking's SO-24A.
When configured as a Call Diverter, the RAD-AMP forwards all incoming calls to a pre-programmed number on a second
line.
When configured as a Telecommuting Extender, the RAD-AMP allows an employee to work from a remote location by pro-
viding most PABX features to be utilized from their home or cell phone.
All programming features, including mode of operation, access codes, security codes, call timers, alert tones and phone
numbers are programmable from a standard Touch Tone phone (see Programming). The RAD-AMP provides a remote
night mode contact input, which can be connected to a remote switch or a dry contact closure provided by your phone sys-
tem. This allows remote operation to enable or disable the RAD-AMP (see Installation). Note: The front panel On/Off
switch must be placed in the Off position to utilize this feature. The RAD-AMP also provides an auxiliary dry contact clo-
sure for user specified applications.
Important: It is crucial that the installer and system owner understands the functions and capabilities of both the RAD-
AMP and the lines and/or PABX stations connected to the RAD-AMP, so that any and all toll fraud and other system abuse
possibilities are understood. This enables the installer and owner to make risk managing decisions about the system in
which the RAD-AMP is put into. Viking Electronics Inc. is not able to assume responsibility since it is a function of the entire
system assembled by the installer/owner. A Viking TR-1 Toll Restrictor may be added to help prevent toll abuse if the PABX
toll restriction is not adequate.
