To increase the GSM signal level, Seneca provides various GSM antenna models for Z-GPRS2 to
reach the minimum signal level in most situations.
Visit (www.seneca.it) or refer to the general catalogue or contact Seneca srl for further information.
CAUTION!
-Insert the SIM card only with Z-GPRS2 off.
-Before inserting the SIM card in Z-GPRS2, delete all SMS on the SIM using a mobile phone
-Wait at least 5 minutes in order for the GSM signal to be correctly read.
CAUTION!
-Contact your telephone service provider for GSM and GPRS service costs especially when using
Z-GPRS2 with a sim issued by a country other than the one in which it is used (international
roaming).
-It is best to estimate telephone costs before setting up Z-GPRS2.
-The cost of each SMS is set by the telephone service provider.
-GPRS send/receive costs can be tied to Kbytes sent/received, a monthly ceiling included in a
package or GPRS connection time. Contact your telephone service provider for further
information.
-For GPRS connections whose costs is associated with connection time, please remember that
communications are active for an amount of time that depends on the number of log rows to be
sent. Typically, a 2 Kbyte data log takes about 10-15 seconds to be sent in addition to the time
necessary to establish the connection (from 5 to 30 seconds) and the time due to any server login
attempts.
-Check the data quantity sent via GPRS and SMS before using Z-GPRS2.
Please remember that mobile phone service providers also consider the entire communication
that permits file transmission (and thus data transmission overhead, the number of connection
attempts, etc.) and not just the dimensions as data traffic in each GPRS transaction.
