GENERAL DESCRIPTION 

 
Using the configuration section you can tailor the operation of the RPC-80 playback 
unit to suit your exact requirements. When you have made your chosen settings you 
return to the normal operating mode and the normal simplicity of control. 
 
These instructions for configuration are offered in a separate manual because it is 
not necessary for everybody involved with the day to day operation of the RPC-80 to 
be familiar with them. This manual assumes that you are reasonably familiar with the 
normal operation of the RPC-80 as described in Manual-1. 
 
The RPC-80 is supplied in a "default" configuration with many of the features 
described in this manual turned off. It is perfectly possible to continue to use the 
playback unit in that form but the extra features, once set up correctly, can extend 
the usefulness of the whole monitoring system. 
 
The setting section allows you to control and adjust some features such as the clock 
without entering the configuration section. This section is described in Manual-1. 
 

ENTERING CONFIGURATION SECTION 

 
The configuration section is protected by a simple password system that is designed 
more to prevent inadvertent operation than to deny access to a determined person. 
 
To enter the configuration section, first enter the setting section in the normal way by 
switching on and holding down any button until the opening display of time and date 
is over. This is described in more detail in Manual-1.

. Change the year number to the 

password number in just the same way that you would set the year. The clock and 
calendar will not be disturbed by this but, if you have set the correct password 
number, you will move into the configuration section. The password number is 

1991

 
The first display asks you to please read this manual before continuing and it is 
important that you should at least have this manual ready to refer to before starting 
to change any settings.
