Model HR70  
Installing the HR70  
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 ½”  
NPT conduit runs.  
Ensure mounting can support 4lbs (1.8kg) and any foreseeable additional  
load.  
Ensure that none of the electrical connection circuits are live.  
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 plugs.  
Use the template provided or the enclosure itself to locate and drill holes for  
#8 or M4 mounting screws.  
Secure the enclosure to the wall.  
Bring cable into the enclosure through the conduit entrance and attach  
individual wires from the exchange (Tip/Ring/Ground) to the terminal block  
(Tip & Ring are not polarity sensitive). If a conduit hub is used, ensure it is  
grounded to the ground stud.  
To change the Tone/Pulse setting to pulse, if required:  
o Move the jumper from pins 1 & 2 of the Tone/Pulse connector to  
pins 2 & 3.  
Tip: The SP70A is  
factory preset for DTMF  
tone.  
o To change the setting back to tone move the jumper back to pins  
1 & 2.  
Reconnect the faceplate harness.  
Ensure all connections are tight, then replace and secure the cover.  
Connect the telephone into the system.  
Test the unit by making calls to and from another unit on the exchange.

Field Repairs  
Note: The only field repair permitted is to change the Tone/Pulse setting and  
the replacement of fuses. All other repairs or alterations must be carried out by  
Guardian Telecom or an Authorized Service Depot. See Warranty and  
Disclaimer for details.  
Fuse Replacement  
Disconnect the telephone from Tip and Ring power supplied by the PABX or  
central office before attempting to replace the fuse.  
Carefully remove the front cover assembly and separate from the housing  
by disconnecting the harness plugs. NOTE that the handset and all  
electronics are attached to the front plate.  
Replace fuse in fuse holder with a 0.25 amp 250V 3AG fast blow fuse.  
Carefully replace the front plate and install all eight screws. Do not over  
tighten the cover screws, there is a flexible gasket between the cover and  
the body. Excessive tightening of the screws deforms the gasket and  
reduces the weather resistance of the set.  
WARNING!  
Replace only with a 0.25 amp 250V 3AG fast blow fuse. Failure to do so will  
void the warranty.  
If, on reconnecting power, the fuse fails, check the telephone system wiring.  
The fuse protects the Tip and Ring line from the telephone system. It is  
usually powered at 48 volts DC and must not be connected to 120 volts AC.

Government Certification  
Attached to the telephone are labels for Industry Canada and the United States Federal Communications Commission. These identify  
equipment certifications indicating the 60 and 70 series telephones meet certain telecommunications network protective, operational  
and safety requirements. These agencies do not guarantee the equipment will operate to the user's satisfaction.  
Before installing this telephone equipment, users should ensure it is permissible to connect the equipment to facilities of the local  
telecommunications company.  
Equipment must be installed using acceptable connection methods. In some cases, the telephone users inside wiring, associated with  
a single line service, may be extended by a certified connector assembly (telephone extension cord). The customer should be aware  
that in some situations compliance with the above conditions may not prevent degradation of service.  
Repairs to certified equipment should be made by a supplier designated authorized maintenance facility.  
For their own protection users should ensure the electrical ground connections of the power utility, telephone lines and internal  
metallic water pipe systems, if present, are connected. This precaution may be particularly important in rural areas.  
CAUTION: Users should not attempt to make ground connections, but should contact the appropriate electrical inspection authority  
or electrician.  
Load Number (LN)  
The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop  
used by the device. Termination on a loop may consist of any combination of devices subject only to the requirement that the total of  
the Load Numbers of all the devices does not exceed 100.  
Notification to Telephone Company  
Upon request, the customer must notify the telephone company of the particular line to which the connection will be made and provide  
the Industry Canada or FCC registration number. The local telephone company may request disconnection of the telephone where  
alterations or malfunctions affect the telephone’s performance.  
United States Federal Communications Commission  
This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the  
instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for Class  
A computing device pursuant to Subpart J of Part 15 of FCC rules, which are designed to provide reasonable protection against such  
interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause  
interference in which case the user, at his own expense, will be required to take whatever measures may be required to correct the  
interference.  
Interference  
There is no guarantee that interference will not occur in a particular installation. If interference to radio or television reception from this  
equipment is suspected, proceed as follows:  
1.  
2.  
3.  
4.  
Unplug the set, check for the interference.  
Re-orient the receiving antenna.

FCC Rules and Ringer Equivalence Number  
This equipment complies with Part 68 of the FCC Rules. On the side of this equipment is a label that contains, among other  
information, the FCC registration number and ringer equivalence number (REN) for this equipment. If requested, this information  
must be provided to the telephone company.  
The REN is used to determine the quantity of devices which may be connected to the telephone line. Excessive RENs on the  
telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs  
should not exceed five. To be certain of the number of devices that may be connected to the line, as determined by the total RENs,  
contact the telephone company to determine the maximum REN for the calling area.  
Service changes and Limitations  
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the  
equipment. If this happens, the telephone company will provide advance notice in order for you to make the necessary modifications  
in order to maintain uninterrupted service.

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 source.  
Product wiring needs to be properly connected to the on-site wiring. Correct wiring  
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  
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.
