+ | ===== Operation ===== | ||
+ | {{: | ||
+ | The wireless station SE-200 consists of the transceiver itself in a robust metal cabinet on a backback carrying frame with a weight of 18,0 kg and a hand cranked generator, which has a weight of another 17,6 kg. | ||
+ | |||
+ | The set can be operated from batteries, it will need a 4,5 V LT / heaters battery (LSA 49122) and a 90 V HT / anode battery (LSA 49121) - or is can be powered from a hand cranked generator, the output power will be increaed from 0,8 to four Watts when using the generator. The generator can be used as a rotary converter operated from 6 V DC from a vehicle battery. | ||
+ | |||
+ | The SE-200 is designed for very uncomplicated operation: next to the telescopic antenna socket and the external antenna jack, You find the main switch combined with the volume control. The frequency is selected by pressing one out of four frequency channel buttons. | ||

+ | A variant of the set for fixed operation (**SE-200 WR**) seems to be rare, a mains power supply war added in later years to allow fixed use of the equipment. | ||

+ | ==== Field use ==== | ||
+ | Because of surplus equipment hat already been acquired and [[Autophon]] was about to introduce their [[SE-206|SE-206/ | ||

+ | The SE-200 was introduced with the troops in 1952/3 and were in use until 1975, in 1977 all the sets were faded out. | ||
