5.13 Receiving alerts via SMS (PCE-VM 40B)
General information
The PCE-VM-40B contains a GSM mobile phone modem for sending text message alerts when vibration
events occur. In this way, the PCE-VM 40B is completely self-sufficient and can be used on remote grid-
bound infrastructures.
The built-in modem supports the frequency bands 850, 900, 1800 and 1900 MHz and can, therefore, be
used worldwide.
Inserting the SIM
To use the GSM functions, a SIM card is needed. In order to insert the SIM card, the PCE-VM 40 case
needs to be opened. To do this, unscrew the antenna and remove the transparent plastic cover by
loosening four cross-headed screws.
Next, loosen the four cross-headed screws of the case and carefully swing the lid towards the connector
side, at the same time ensuring you do not pull the cables.
