Repair Strategy

The Service Support Tool software helps you to determine whether a fault is a hardware, software or RF-
related problem. Any maintenance and repair procedures beyond the level covered in the Instructions for
Use are limited to:
• unit exchange for
– the base station
– the transducers
• replacement of
– the top cover assembly, including human interface board
– the power supply, including metal chassis
– two fuses in the power supply
– the transducer battery
– the transducer ventilation knob
Repair or replacement of individual components on the boards is not supported, and should never be
attempted.
For any problem related to connecting the base station to an antenna system, refer to the M2600A
Telemetry System's Service Training and Reference Guide.
For tests that you are required to perform after repairs, refer to "When to Perform Safety Tests" on
page 38.

Pre-Installation Considerations

There are a number of factors you need to consider that influence how you install the Avalon CTS.

When is the Avalon CTS Customer Installable?

The Avalon CTS is intended to be customer installable under the following conditions:
• The system in its standard configuration is an "out-of-the-box", standalone system, delivered with
automatic frequency allocation, and is intended to be used with the standard antenna supplied, giving a
line-of-sight operating range up to 100m/300ft.
• There are less than ten stand-alone systems in the institution.
• Connection to an antenna system is not planned.
• No other telemetry devices are used in the institution that can influence, or be influenced by, the
Avalon CTS.
• There are no other sources of RF interference that influence the operation of the Avalon CTS.
• There are no country-specific regulations requiring special configuration.
Installation should be carried out by qualified technical personnel.
If you need to mount the Avalon CTS, or use the antenna extension mounting kit (M2720A Option
K01), see page 10 for further details.
