This alternative procedure requires a specific downloading software tool. The Alternative Download procedure can be used for both the GSM & GPS sections. The alternative download procedure is started when this input is low during the power ON of the modem. In normal mode, this pin has to be left open.
WM_PRJ_Q2501_PTS_001 – 003 March 2004 2.5.4.2 Reset sequence To activate the « emergency » reset sequence, the ~RST signal has to be set to low for 500 µs 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.

WM_PRJ_Q2501_PTS_001 – 003 March 2004 6.2 Safety recommendations (for information only) IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM APPLICATION BASED ON WISMO Quik Q2501 PLEASE READ THIS INFORMATION CAREFULLY 6.2.1 RF safety 6.2.1.1 General Your application using the WISMO Quik Q2501 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.
WM_PRJ_Q2501_PTS_001 – 003 March 2004 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.
WM_PRJ_Q2501_PTS_001 – 003 March 2004 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.
