The following numbers refer to Figure 38 on page 59:

1 = Flat cable pins

2 = Battery

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.
