Remarks

Information of the company Panasonic/Technics about this device: This device is a quartz synthesizer VHF/MW stereo tuner. DC amplifier, detector and stereo decoder. Automatic 19kHz pilot tone suppression provides a linear frequency response from 5 Hz to 18 kHz (+0.2dB, -0.5dB). Ceramic filters with linear group delay in the IF stage guarantee a selectivity of high 85dB (VHF) and 55dB (MW).
The quartz synthesizer allows pre-programming of up to eight FM and AM stations, which can then be recalled at the touch of a button. The station set before switching off is retained in the memory.
Equipped with a timer that can be programmed for two programs daily plus an additional program once daily or weekly, and also serves as a digital time clock.
This model came on the market in 1982/1983 (in Germany).

Note:
But is already shown in the Technics catalogue 1980/81.

Hint: When buying a used model, be sure to ask the vendor about the brightness of the display: after 25 years of continuous operation, these are usually no longer recognizable and are no longer offered by the manufacturer (Futaba, Japan).
