Installing the

WRT

• The WRT is set to tone dialing when shipped. If pulse dialing is required

see the section on Setting Tone/Pulse Operation.

See: Figure 5 - Setting

Dialing Mode &

Installation

• 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

wiring.

See: Figure 2 - Overall

Dimensions - Standard

Models

• Ensure mounting can support .5 lbs (2.95 kg) plus any additional,

foreseeable load.

• Ensure that none of the electrical connection circuits are live.

Mounting Without Optional Mounting Plate

• Use the appropriate template to locate and drill holes for mounting screws.

Use #10 or M5 screws to secure the unit to the wall. Use anchors in plaster

or cement to provide a firm grip for the mounting screws. Use sturdy hollow-

wall fasteners to mount the set to drywall.

See: Figure 2 - Overall

Dimensions - Standard

Models

• Loosen the five captive screws in the faceplate and swing the faceplate to

the left. If the set is on a vertical surface the faceplate will stay open like a

book in this position. Take care not to disturb the internal wiring.

• Secure the unit to the wall.

• Replace the faceplate. Do not over tighten the screws.

Mounting With Optional Mounting Plate

• Use the appropriate template to locate and drill holes for mounting screws.

• Secure the unit to the wall.

Wiring the WRT to the Telephone System

• Remove the wiring access cover plate.

• Bring cable into the enclosure through the conduit entrance and attach

individual wires from the exchange – Tip/Ring/Ground – to the surge

arrestor (Tip & Ring are not polarity sensitive). If a conduit hub is used,

ensure it is grounded to the ground stud.

• Replace the wiring access cover plate.

Final Check

• Check the set visually for loose screws and trapped wires. Check that the

handset hangs freely in the cradle and that the handset cord is not trapped

by the door.

• Check that the faceplate is snug to its gasket, paying particular attention to

the area around the cradle. Check that the door closes flush to the housing.

• Test the unit by calling to and from another unit on the exchange.

Setting Dialing Mod

The WRT is shipped from the factory set for DTMF (Tone) dialing mode. If

loop disconnect (Pulse) dialing is required proceed as follows.

See: Figure 5 - Setting

Dialing Mode &

Installation

• Loosen the five captive screws in the faceplate and swing the faceplate to

the left. If the set is on a vertical surface the faceplate will stay open like a

book in this position. Take care not to disturb the internal wiring.

• Change the position of the Tone/Pulse jumper on the circuit board to Pulse,

as indicated on the label.

• The set will now be in pulse dialing mode, it can be returned to tone mode

by changing the position of the jumper back to the Tone position.

• Carefully replace the front plate and install all five 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.

Field Repairs & Adjustments

Field repairs may only be carried out by qualified technicians using OEM parts.

Substitution of parts voids warranty and may pose a hazard to users of the

equipment.

See: Replacement Parts

• Disconnect the telephone from Tip and Ring power supplied by the PABX

or central office before making repairs or adjustments.

• Loosen the five captive screws in the faceplate and swing the faceplate to

the left. If the set is on a vertical surface the faceplate will stay open like a

book in this position. Take care not to disturb the internal wiring.

• Perform the necessary repairs or adjustments.

• Carefully replace the front plate and install all five 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.

Note: Ensure that

connections are secure

efore replacing

faceplate.

Fuse Replacement

• Remove the old fuse by pushing in the end cap of the fuse holder and

turning counterclockwise to open. Insert a new 0.25 amp, 250Volt, 3AG

fast blow fuse and close the fuse holder.

See: Figure 6 - Fuse

Replacement

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.
