The "Messenger 3" cassette player

此网页目前不提供中文简体翻译.

The "Messenger 3" is a mono cassette player designed to operate primarily where there are no batteries or other sources of power available. It has a socket for connection to an external power source such as a 6 volt DC battery pack or eliminator. Very low power consumption of about 1.2W at full volume also makes it ideal for use with solar panels.

The basic model is mains powered (110V or 220-240V AC). A second hand wind model is in development but not yet available: it will add a crank handle coupled via gears to a generator, to supply electrical power to operate the machine.

Buttons operate the Play, Fast Forward and Stop functions. The keys are colour-coded (Green and Red) to facilitate use by non-literate people. The machine does not record.

The "Messenger 3" players are strongly built, using a very simple design and incorporating many metal parts. The case is made from tough ABS plastic, with red or black top and black bottom. Reliability and serviceability are high priorities in the design and manufacture of these players. They are assembled by trained volunteers at our facilities in Sydney, and sold at a heavily subsidised price for missionaries and indigenous churches.

The player comes with a spare parts kit which includes belts, screws etc. Additional parts are available at reasonable prices.
