IMPORTANT WARNING
Elevator Equipment MUST BE maintained and installed by qualified elevator service technicians and elevator contractors. Most states require that both mechanic and elevator
company be licensed in order to perform repair and replacement. If you are not a licensed elevator company or mechanic, you are putting your life and those that ride elevators at risk.
Failure to have a qualified technician repair or install elevator equipment will nullify any warranty and may cause death or injury.

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.
•
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.

•
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”.
