Figure 3 & 4 - Installation SCT-20-H
Installing the SCT-H
•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.
See: Figure 2 -
Dimensions
•Ensure mounting can support 4lbs (1.8kg) and any additional foreseeable
load.
•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.
•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.
To change the Tone/Pulse setting to pulse, if required:
Tip: The SCT-H is
factory preset for DTMF
tone.
See: Figure 3 -
Installation SCT-20-H
o Move the jumper from pins 1 & 2 of the Tone/Pulse connector to
pins 2 & 3.
o To change the setting back to tone move the jumper back to pins 1 & 2.
•Use the template provided to locate and drill holes for #8 or M4 mounting
screws.
•Attach the back box to the wall. If weather resistance is important in your
application select washers that will assist in sealing the mounting holes.
Tip: Use #8 or M4
screws to secure the unit
to the wall.
Wiring the SCT-H to the Telephone System
•Use the conduit hub provided or fit an appropriate cable gland, grommet or
conduit connector to the 7/8” opening in the bottom of the enclosure.
•Bring cable into the enclosure through the opening and attach individual
wires from the exchange (Tip/Ring/Ground) to the connector (Tip & Ring are
not polarity sensitive). If a conduit hub is used, ensure it is grounded to the
ground stud.
See: Figure 3 - Figure
4 - Installation SCT-20-
H
•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.

Field Repairs
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 attempting to make repairs.
•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.
See: Figure 3 -
Installation SCT-10-H &
SCT-30-H & Figure 4 -
Installation SCT-20-H
•Perform the necessary repairs or adjustments.
•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.
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.
Changing the Tone/Pulse Setting
•Set the Tone/Pulse jumper for the desired operation. For pulse, set the
jumper between the center pin and the “P”, for tone set it between the
center pin and “T”.

Cleaning Tips for the SCT-20-H Telephone
These Telephones may occasionally need to be cleaned to maintain appearance. Generally, wiping
the surface with a clean, water-dampened cloth will remove most films or residues. If the soiling is
too stubborn for plain water, a mild detergent solution may be used. Be sure to wipe away any
detergent residue with a plain water dampened cloth. The Telephone may be cleanedwith any
general-purpose household glass and surface type cleaner. Do not spray the telephonedirectly!
Spray the cleaner on a soft cloth then wipe the surface. Pre-treated cloths such as those used for
eyeglasses or cameras may be used to clean the Telephone. Premoistened towelettes may also be
used, however, avoid those containing lanolin or aloe, as they will leave a slippery residue. The
handset and surface of the telephone may be cleaned with disinfectants used for general cleaning
in a medical environment. Isopropyl alcohol may be used applied with a cloth. Avoid using alcohol
on silicon-based keypads, since doing so may significantly degrade legibility.
•Do not use furniture polishes, waxes or plasticizer-based cleaner (Armor All etc.)
•Do not use lanolin, aloe, glycerin or other skin care type products.
•Do not apply any solvent such as acetone, mineral spirits etc.
•Do not directly spray or immerse the handset.
Storage
General Storage (All situations):
•Note any stacking limits or warnings on packaging (if any).
•Do not store in temperatures over +80C.
•Store in original packaging if possible until needed.
Long Term Storage (> 6 Months):
•If area is air-conditioned and not subject to high changes in humidity, continue to store in
original packaging.
•If wide humidity shifts are expected, then use these steps:
oRemove product from packaging (including plastic bags) and store on shelf in open air.
oIf area is subject to a high degree of dust, to help maintain cosmetic appearance you can
cover with cloth (Do not cover with plastic or materials that will trap moisture) or clean
periodically.
oDo not store out of packaging long term where they are exposed to sunlight. Long-term
exposure to UV may cause fading on plastic parts.
