Installation
•The WRT-10-H is set to tone dialing when shipped. If pulse dialing is
required, see the section on Setting Tone/Pulse Operation.
See: Figure 3 - Setting
Dialing Mode &
Installation
•Follow all appropriate electrical codes and use only approved electrical
fittings for the installation.
•To avoid the possibility of creating sparks in a hazardous atmosphere
disconnect the wiring at the demarcation block or ensure that the area is
non-hazardous before proceeding.
•To avoid shock hazard ensure that none of the electrical connection circuits
are live by disconnecting the Tip and Ring conductors at the demarcation
block.
•Choose a wall location that is free of obstructions and permits space for
wiring.
See: Figure 2 - Overall
Dimensions
•Ensure mounting can support 6.5 lbs (2.95 kg) plus any additional,
foreseeable load.
•Use the template to locate and drill holes for mounting screws.
See: Figure 2 - Overall
Dimensions
•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.
•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.
•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.
•Connect the Tip and Ring conductors at the demarcation block.
•Test the unit by calling to and from another unit on the exchange.

Setting Dialing Mode
The WRT-H is shipped from the factory set for DTMF (Tone) dialingmode. If
loop disconnect (Pulse) dialing is required proceed as follows.
See: Figure 3 - Setting
Dialing Mode &
Installation
•Disconnect the wiring at the demarcation block or ensure that the area is
non-hazardous before proceeding.
•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.
•Disconnect the wiring at the demarcation block or ensure that the area is
non-hazardous before proceeding.
•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.
See: Figure 4 - Fuse
Replacement
•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
before 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.
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.
