Aerial Connection

Carefully connect the aerial. Do not operate the CM910 without an aerial connected. Refer
to Technical Details section for alternatives. The aerial must be vertically orientated.

Install the SIM Card

Before installing the SIM card, ensure that it is activated. We recommend you insert the SIM
into a regular cell phone to check this. Carefully remove the CM910 cover by prising the
side panels close to the retaining dimples.

Locate the SIM card holder adjacent to the USB and RS232 connectors. Push the top part of

the holder in the direction of the “Open” arrows (away from the aerial). 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 aerial to “Lock”.
