Warnings & Cautions
Warnings
Dangerous voltages exist in this equipment. Do not attempt
any repair without first switching off power to the system, at
the front panel switch, and removing the power input
connector.
Nickel, cadmium and lithium are toxic substances. A nickel
cadmium battery or lithium battery is dangerous if broken or
dismantled. If any battery chemicals come into contact with
skin, wash with copious amount of water, and seek medical
attention as required. If the battery is swallowed seek
immediate medical attention. Return any faulty batteries to
the manufacturer, properly packaged, for disposal.
The liquid crystal display can be hazardous if broken or
dismantled. If any liquid crystal chemicals come into contact
with skin, wash with soap and water. Return the faulty display
to the factory, for disposal.
Most board assemblies contain tantalum capacitors or
electrolytic capacitors. Both types can explode under fault
conditions. Take appropriate precautions when servicing the
unit with the lid removed.
Cautions
This unit should only be serviced by qualified personnel, no
user serviceable parts inside.
Several Board Assemblies contain static sensitive devices.
Appropriate procedures must be used when handling these
items.
Care must be taken in physically handling the system. When
lifting the system, appropriate lifting procedures must be
followed that appropriate to the weight of the unit.

Chapter 1:
Introduction to the M211 Time System
Product Overview
The M211 Time System from Time & Frequency Solutions Ltd
is designed for use in applications where reliable time
information is required; such as time display, systems
synchronisation or scientific experimentation.
The M211 Time System provides a Master Clock based upon
an internal central microprocessor. This microprocessor
provides timekeeping functions and has an alphanumeric
display with keypad for control, configuration and reporting
of the unit.
The design of the M211 Time System allows inclusion of up to
9 options from a large range of modules within a 3U rack
format. This gives the M211 Time System the ability to
synchronise to various national and international time
standards, output time and date in various formats, and
perform auxiliary tasks.
The timing oscillator within the M211 Time System is
specified, at time of order, to provide the required precision
for the particular application.
