This transceiver has been developed in response to a market demand for a low cost, simple to use, fully immersible emergency radio. It provides a means of communication from aircraft to personnel in a distress situation where they can not be reached and no alternative communication method exists. The unit is rugged and fully sealed and can withstand water immersion making it ideal for marine distress situations. The standard frequency is 123.1MHz although if the unit is intended for applications other than search and rescue communication, an alternative frequency crystal can be fitted. Each unit is supplied with a tough fronted pouch so that it can be stored safely without the likelihood of accidental activation. To reduce the possibility of loss, the unit can be secured by a lanyard fitted to one of the loops on the pouch or the loop on the case. The 1135 is powered by a replaceable lithium battery which provides a shelf life of five years and an endurance of more than fifty hours when the unit is activated.
