Tip
: Power cable should be less than 3 meters (10 feet). Do not use thin cables such as
alarm cable or CAT5 cable to power this unit. The standby current is 45mA, however this
increases to 200mA when dialling out, with spikes of current draw up to 2 amps.
Power up the unit. After 10 seconds or so, the GSM LED should change from a fast flashing
frequency to a slow flash, every 3 seconds or so. If this does not happen, power the unit off,
and check the SIM card is seated correctly and ensure the steps above regarding the SIM
card have been followed.
