Power consumption standby (logged in): . max. approx. 500 mW 
Power consumption data connection (connect): max. approx. 2 W 
Power consumption power down: max. approx. 200 mW 
Power input sleep: max. approx. 300 mW

This values have been established for a signal field strength of 20 (AT+CSQ).  The current 
consumption and therefore the power consumption may increase for poor network 
conditions. 
These are average values for estimating the current consumption. The used power 
supply unit should be able to supply up to 10 W at short notice (pulse duration 577 µs for 
period 4.67 ms) to ensure proper operation. 
 

Terminal open/unwired: Normal state 
 
Terminal connected to GND (terminal 2): Reset 
 
Reset duration: minimum 300 ms 
 
When the GND potential is removed once more, the device is in initial state. 
 
ATTENTION! All settings that have not been stored will be lost during a reset. 
 
The reset terminal is also used to bring the INSYS GSM small from the power down state 
into normal state. 
 
The reset terminal is to be considered as replacement for the combination of the pins 
PD_IN and IGT for the Siemens Cellular Engines TC35i or TC35i terminal, respectively.
