Installing the CIR-41
• Follow all appropriate electrical codes and use only approved electrical
fittings for the installation.
• Choose a wall location that is free of obstructions and permits space for
cable or conduit runs.
• Ensure mounting can support 4lbs (1.8kg) and any additional load to which
the telephone may be subjected.
• Ensure that none of the electrical connection circuits are live.
• Bring Tip, Ring and Ground wiring to the location where the wiring access
opening in the back of the CIR-41 will be when the telephone is installed.
• Remove the eight (8) cover screws from the front of the unit and carefully
remove the front cover assembly. NOTE that the handset and all
electronics are attached to the front plate. The front cover may be
separated from the back box by disconnecting the harness plug.
• Use the enclosure as a template to locate and drill holes for #8 or M4
mounting screws or other suitable attachments.
• Feed Tip, Ring and Ground wiring through the wiring access opening and
secure the unit to the wall.
• Attach individual wires from the exchange (Tip/Ring/Ground) to the terminal
strip (Tip & Ring are not polarity sensitive), or plug the RJ11 connector into
the socket if this termination method was chosen. Even if an RJ11
connector is used an approved earth ground must still be provided to the
ground connection on the terminal strip.
• Ensure all connections are tight, then replace and secure the cover.
• Connect the telephone into the system.
• Test the unit by calling to and from another unit on the exchange.
See: Figure 2 Dimensions
Tip: The CIR-41 may be
wired directly to the
terminal block or an
RJ11 connector may be
used.
Tip: Use the driver bit
provided to remove the
tamper resistant screws.
See: Figure 3 Mounting.
See: Figure 4 - Electrical
Connections
Note: an approved earth
ground must be
connected to the ground
position on the terminal
strip regardless of Tip
and Ring wiring method.
Operating the CIR-41
• The CIR-41 Autodialer phone is designed for receiving calls and for
connecting to a single number – if the PABX is programmed to perform this
function. Calling out is automatic simply by removing the handset from the
cradle.

Guardian Product Return
Guardian products have been quality tested and are in full working order when shipped from
the factory, given the rugged nature of these products shipping is not expected to damage a
unit. In the unlikely event of a malfunction, Guardian follows the three step procedure below.
Step I - On-Site Correction
•The most common source of difficulties with a new product is improper installation in one of
two ways: incorrect wiring connections or connection to an incorrect power sour ce.
•Product wiring needs to be properly connected to the on-site wiring. Correct wi ring
instructions are shown in the user manual included with the product.
•Connecting a telephone to a standard power source, rather than tip & ring, will blow the
telephone’s internal, user-replaceable fuse. In the event of fuse burn-out, disconnect the
telephone from the power source, replace the fuse, and reconnect following the wiring
diagrams provided with the product.
Step II - Return Materials Authorization (RMA)
•When a product has been installed following user manual instructions, and the unit fails to
operate, the user must contact Guardian Telecom to obtain authorization to return the
product. This can be done by completing a RMA form online at
www.guardiantelecom.com, or by calling the service telephone number given in this
manual.
•After providing information on the product, the owner and the nature of the problem,
Guardian will issue a RMA number, to be shown on documentation returned with the
product.
•In addition to the RMA number, shipping documents should include name, address and
telephone number of the owner along with contact information for the person responsible
for the repair and/or the user who identified the malfunction.
•(Where a product is being returned for repair from outside of Canada, customs
documentation must show the product’s serial number, date of export [date of purchase],
and a notation that the equipment is: “Canadian goods returning.”)
Step III - Factory Authorized Service
•Once received, each product is carefully inspected and tested. If the product is under
warranty, repairs are completed and the product returned to the owner, generally within
five working days of receipt by the factory.
•A product that has been subjected to misuse, neglect or accident or is beyond the warranty
period will be evaluated. The service department will provide the owner’s representative
with a repair cost estimate. Once approved, repairs are completed and the product
returned, generally within five working days.
