Consequently, the module should be subject to ESD handling precautions that typically apply to
ESD sensitive components. Proper ESD handling and packaging procedures must be applied
throughout the processing, handling and operation of any application that incorporates this
module.

Using the device in unmanned high reliability applications
The module features software and hardware watchdogs which are incorporated inside the CPU.
While we believe that this is a reliable method of keeping the module in operational condition,
there are parts of the module that can’t be monitored for proper operation to 100%. For example
the module chip has a firmware that resides in the chips RAM. The firmware can’t be read back
or reloaded, without interrupting reception. Hence the module can’t reload this automatically by
itself without causing breaks in communication. To avoid the module from ending up in a state
where for example the module chip firmware is corrupted for example by ionizing radiation, it is
recommended that the controlling system implements some form of watchdog function for the
module. This can be done for example if the system knows that data should be received every
second, and no data has been received for a minute – then do a module restart using the
ENA_MOD pin or by issuing a restart command, or a cold boot by toggling VCC_IN low and
high again.
