Getting Started
Antenna Connection
Carefully connect the antenna. The antenna must be vertically orientated.
Alternative high gain and externally mounting antenna options are available.
Warning
–
DO NOT operate the SMS Lite without an antenna connected.
SIM Card Installation
Before installing the SIM card, ensure that it is registered and activated on the Telco’s network.
We recommend you insert the SIM into a regular cell phone and check that you can send and receive
messages. Carefully remove the SMS Lite cover by prising the side panels close to the retaining
dimples.
Locate the SIM card holder adjacent to the antenna. Push the top of the holder in the direction of the
“Open” arrows to “Unlock” (toward
antenna), then flip open (away from the antenna).
Carefully insert the SIM card from your chosen Telco. Be careful to orientate the card correctly, once
in place carefully slide the plastic retainer towards the antenna
to “Lock”.
