6.8. Notification
Please follow the principles below in module application.
6.8.1. Coating
If a conformal coating is necessary for the module, do NOT use any coating material that may chemically
react with the PCB or shielding cover, and prevent the coating material from flowing into the module
6.8.2. Cleaning
Avoid using ultrasonic technology for module cleaning since it can damage crystals inside the module.
To meet this operating temperature range, you need to ensure effective thermal dissipation, for example, by adding
passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range, the module meets 3GPP specifications.
To meet this extended temperature range, you need to ensure effective thermal dissipation, for example, by adding
passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range, the module remains the ability to establish
and maintain functions such as voice*, SMS, etc., without any unrecoverable malfunction. Radio spectrum and radio
network are not influenced, while one or more specifications, such as P
out
, may undergo a reduction in value, exceeding the
specified tolerances of 3GPP. When the temperature returns to the normal operating temperature level, the module will
meet 3GPP specifications again.
