An 8-page booklet about the DENON DOing - the “field compo” H-5, a transformable portable boombox for the beach at ¥94,800. The 40-watt system assembles from three detachable blocks: an H-5TD tuner-deck with MM/MC phono input, an H-5A amplifier and a pair of two-way H-5S speakers, running off mains, eight UM-1 batteries or a car battery. The whole catalog is early-80s beach lifestyle (surfing, hang-gliding, a seaside shed) under a slogan of verbs - LISTENING, DUBBING, WALKING, BIRD WATCHING. The back page lists the priced options: the DP-11F quartz turntable (¥39,800), the DM-155 and DM-123 microphones, the folding Pocket AH-P5 headphones and the ADA-5 battery cord.
