PERATING THE
SIM300CZ
TELEPHONE
The SIM300CZ industrial cellular telephone, similar as any other cellular telephone, can be
operated by SIM activation card. The user of the GSM-4S module and the SIM300CZ
telephone has to obtain such card. The SIM card is inserted into a special socket provided at
the bottom of the printed circuit board. PIN code, if necessary, is entered in the module’s
memory by the service function from the sub-menu "GSM options". The change of PIN code
or entering PUK code, if needed, is only possible after putting the SIM card into an ordinary
cellular telephone.
The SIM300CZ cellular telephone set is delivered with special cable fitted, having
a connector for external antenna (see fig. 2).
5. I
NSTALLATION
It should be remembered during installation that the GSM-4S module must not be located in
the vicinity of electrical installations, since this may involve a risk of malfunctioning. Pay
special attention to how the cable is laid between the module and the telephone jack of the
alarm control panel.
Caution: Never turn on power supply of the module and SIM300CZ telephone
without external antenna connected.
