General operating instructions
1.
The Indutel GSM is intended for use with a solar panel or a DC voltage of 5V. An internal
battery serves as a voltage buffer. At least one SIM card is required for operation. The SIM
cards must have their PIN request deactivated.
2.
The telephone has a receiver hook with a contact-magnet as hook switch. To end a phone
call, the receiver has to be placed back.
3.
Telephone settings are programmed by sending information via SMS to the Indutel GSM.
4.
Successful completion of programming is confirmed via a return SMS.
5.
When the solar panel is in operation, the panel must be oriented in such a way that sufficient
charging of the battery is ensured. The battery discharge status is reported via SMS to the
number pre-programmed for this purpose.
6.
When receiving calls, the Indutel GSM will ring at a volume and with the melody programmed
by you.
