NOTES

[1] This condition indicates that no connection to the GSM network has been made. Possible causes are...

• Improper antenna connection, no antenna, or faulty antenna. Note operating the GSM modem with no antenna can

cause damage.

• GSM module is too far from available base station.

• Provider network or GSM base station malfunction.

[2] This condition indicates that the modem can connect but is reaching the limits of useful option. The top of the range will

possibly still provide a reliable link, however, atmospheric conditions such as heavy rain may degrade the link further.

[3] It may still be possible to achieve a link to the higher levels. However, it is likely that the link will be intermittent.
