After a reset or a power up, it will usually take at least 10 seconds before
the data logger module is initialized. The real time clock and the data
logging and reading functions are not available before the initialization is
complete.
The indicator LED on the module will blink green during normal
operation. If the LED is lit in red color, there is a problem with the
module. The transmitter will also indicate the problem by activating the
"Add-on module connection failure" error. If the module is not operating
correctly, the transmitter must be sent to Vaisala for maintenance.
The data logger module must be installed at the factory (when ordering
the transmitter), or by a Vaisala Service Center. Once installed, the
module is automatically used by the transmitter. When the module
requires a new battery, the transmitter must be sent to Vaisala for
maintenance.
