Dark blue printed instructions on paper mounted on a buff coloured cardboard card.LAMPS, SIGNALLING DAYLIGHT, SHORT RANGE Lamp can be used either (1) on the spike and spike extension stuck in the ground or (2) in the hand if necessary, or (3) withe the adaptor provided on a standard helio stand. SIGHTING TUBE: It is important to see that the lamp is so aligned that the distant receiving station is at the centre of the cross slots and maintained in that position the whole time that signals are being sent. BULBS: when fitting a new bulb, insert the locating tongue on the washer to the front and push the stem right back in the slot. BATTERIES: The correct replacment unit for this set is 8 "S" cells connected "in series". Screw up both terminal nuts tightly, ans see thar all connectors are in position. NIGHT SIGNALLING: An adjustable screen is supplied for reducing the light and one of the colour discs should always be used in conjunction with it when signalling at night under enemy observation. KEY CONNECTIONS. Use the two-pin plug in No.1 socket as long as the light is good enough, then cahnge to No.2. This will greatly lengthen the life of bulb. Used bulbs and batteries should not be relaced in the box, but discarded and a fresh supply obtained. Get a copy of detailed instructions "How to Use" this signalling outfit.

This Favag Timer apparatus was a part of the first electronic control system -(1960's), in Victoria), which worked using telephone stepping selectors to convey a change in voltage providing a regulated pulse from the control centre(Mount Beauty) to the remote Power Stations opening and closing (stop/start) of various devices at the Power Station and a return signal confirmed the action taken. Testing of this unit was carried out using a "dummy" device at the remote Power Station so as not to disrupt the power plant's operation. This timer was one of many electrical apparatus connected to the large SEC Victoria Hydro Scheme's electrical power producing generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro Schemes was achieved from the early 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce,inclusion of skilled and unskilled, migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This Favag Timer was one of the crucial pieces of equipment that made it possible for the Mount Beauty Terminal Station to control the operations of these Power Stations; McKay, Clover, West Kiewa Power Stations and the Dederang Terminal Station.This aluminium and anodised "FAVAG" (pulse) timer is fastened to a base structure which comes with its own metal cover that is fastened by two metal hooks. From the top of these hooks runs a thick leather "carry" strap.The instrument, itself, a small "micro motor" at one end tape feeding spool on the other. Aluminium metal structures offer a preventative barrier against any electronic spikes from static electricity sources. There are two toggle switches to the bottom right hand side and twelve coloured "pin" connection points.There is a sliding access sleeve which exposes a circuit board.with various leads fastened on each side. In front of one of this slide are two "screw in" fuses, spare fuses are in a small envelope taped above. Circuit diagrams are etched white on black background on the top face of the main structure. At the base of the back section is a two pronged input terminal. There is a fine black rubber layer (cushioning) for the mian top cover.On the cover fastened with two rivets "FAVAG" underneath in small print "Fabrique d'appareils electriques S.A." underneathe "NEUCHATEL-SUISSE". on one end is a "STATE ELECTRICITY COMMISSION OF VICTORIA" metal label screwed on.The back label has manufacturers' type and model number.sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth

Radio Telephone was minuted during the war. It was approved in 1944 for State Electricity Commission of Victoria use only. It was completed by the end of 1946. Used by the State Electricity Commission of Victoria at Bogong during the construction of the Kiewa Hydro Electric Scheme to connect with head office in Melbourne. It allows one conversation at a time using traffic controls in an unusual system of radio telephone providing communication. At the time it was unique in Australia and installed by the S.E.C.V. technicians. It provided an unattended shortwave radio link between two ordinary telephone switchboards, connecting any of the S.E.C.V.'s internal lines with the telephone system at Bogong and the construction camps beyond. From Bogong, radio phones connect to the outpost stations on the High Plains far above the snow-line. In operation, the service is similar to a normal telephone system but dispenses with the physical connection of wires and poles between the main terminals. Historical: This type of headphone was recommended for amateurs. It may have been used by operators on the Switchboard at Bogong or one of the construction camps on the Kiewa Hydro Electric Scheme. The S.E.C.V installed this unique system of communication to operate their branches especially at Bogong and beyond where the distance was great and often limited by the terrain and weather.Used for a transmitter radio or Radio Telephone as installed by the State Electricity Commission of Victoria 2 round ear pieces.
