This reset procedure has to be considered as an emergency reset or for alternative download procedure described above. This signal can also be used as an output to provide a reset to an external device. If no external reset is necessary this pin can be left open.
MG260 Product Specification 2.5.3.2 Reset sequence To activate the « emergency » reset sequence, the RSTEXTN signal has to be set to low for 500s minimum. As soon as the reset is complete, the AT interface answers « OK » to the application. For this, the application has to send AT. If the application manages hardware flow control, the AT command can be sent during the initialization phase. Another solution is to use the AT+WIND command to get an unsolicited status from the module.

MG260 Product Specification 6.2 Safety recommendations (for information only) IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM APPLICATION BASED ON MG260 PLEASE READ THIS INFORMATION CAREFULLY 6.2.1 RF safety 6.2.1.1 General Your application using the MG260 module is based on the GSM standard for cellular technology. The GSM standard is spread all over the world. It covers Europe, Asia and some parts of America and Africa. This is the most used telecommunication standard.
MG260 Product Specification 6.2.1.4 Antenna care and replacement Do not use the GSM terminal with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Replace a damaged antenna immediately. Consult your manual to see if you may change the antenna yourself. If so, use only a manufacturer-approved antenna. Otherwise, have your antenna repaired by a qualified technician. Use only the supplied or approved antenna.
MG260 Product Specification 6.2.2.5 Aircraft Turn your terminal OFF before boarding any aircraft. Use it on the ground only with crew permission. Do not use it in the air. To prevent possible interference with aircraft systems, Federal Aviation Administration (FAA) regulations require you to have permission from a crew member to use your terminal while the aircraft is on the ground. To prevent interference with cellular systems, local RF regulations prohibit using your modem while airborne. 6.2.2.
