GENERAL
1 INTRODUCTION
The Commander AN-61 6 is an electronic key telephone system providing 6 exchange lines and 16
stations. It is an electronic system using hardware and software modules packaged to provide various
economical solutions. The stations have a very modern and stylish appearance.
The main equipment and the stations are controlled by microprocessors with masked programs providing a
wide range of facilities demanded by the users of key systems.
*WARNINGS*
A. This equipment contains a considerable number of MOS, and other static sensitive components. To
reduce the incidence of the premature failure due to static discharge, the following precautions
MUST be taken:
Always ensure that power is disconnected before plugging PBAs.
Always discharge static from yourself by touching a conductive part of the main equipment
before handling boards.
Handle
by the edge or by the handles. Do not handle PBA tracks, components or edge
connectors (contaminants introduced by fingers can cause corrosion and high resistance
connections).
Components are physically delicate. Finger pressure on a component can fracture, but not
necessarily break component leads: a future fault.
To protect against physical damage and damage due to static discharge,
must ALWAYS be
inserted into a conductive ANTI-STATIC bag and placed in the protective container provided with the
new item. In the case of the CPB-AN remove the battery and package separately.
These procedures apply equally to both working and faulty
Careless handling, storage and
transporting will cause secondary or future faults.
B. To prevent the likelihood of damage to electronic components, power should be switched off before
working on the systems.
C. The cabling between the Main Equipment and Stations is polarity sensitive. It is essential that the
correct polarity be maintained from the Main Equipment to the Stations and pairs must not be
swapped. Care must be exercised when checking voltages on cabling.

D. Power supplies are powered from the 240 volt mains supply and hazardous voltages are present
within. Do not attempt to repair these devices in the field.
E. CPB-AN BOARDS
If this PBA is replaced, all site dependant data and abbreviated dial numbers are lost. It will be
necessary to re-programme the system.
The battery may be changed by removal of the daughter board (without loss of any
programmed data) with the CPB-AN power up, i.e. power on.
F. TMB-AN BOARDS
If this PBA or the CPB-AN PBA is replaced, then the system clock is lost and must be
reprogrammed.
1.2 FEATURES AND FACILITIES
1.2.1 Direct Exchange Line Access
In general, any station can access any exchange line to answer an incoming or make an outgoing call. Up to
8 Exclusive Exchange Lines may be provided each of which can be accessed by one station only.
1.2.2 Last Number Redial
The user may recall the last number
by dialling
after seizing an exchange line and pressing the
Dial Control
key.
