PANEL CARE
The digital GSM panel facia is brushed stainless steel. It is important that the facia is cleaned on regular occasions to prevent dirt
build up and tarnishing of the metal. A general household metal polish can be used but care should be taken to follow the grain
of the metal when polishing and also avoid any polish build up around the panel buttons which may prevent the buttons from
operating correctly.
FITTING A SIM CARD
After connecting the power supply, antenna, lock output and any auxiliary devices as shown in this manual and before powering
up, a SIM card must be installed (the SIM must already be registered with the network provider). The SIM holder can be found on the
back of the module next to the SMA antenna connection. A SIM card from most network providers can be used with the exception
of the 3 network. Follow the steps below to insert the SIM card:
1. First slide the SIM holder on the back of the digital GSM
module down until it ‘clicks’, as shown in
