    QTM525 modules are equipped, integration sequence from QTM0 to QTM3 is recommended, leave unused connectors NC (Contact Dejero Labs Inc as the RFC has to be updated to reflect the number of QTMs). Note that for high-power usage, it’s not recommended to leave any QTM527 NC as it will violate 3GPP EIRP compliance for PC1.

    Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the Dejero Labs Inc module are used in a normal manner with a well-constructed network, the Dejero Labs Inc module should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property.
