2 Power Connection
The power mains power connection is via an IEC connector fitted at the rear. Insert the supplied power lead and connect to a mains outlet. Switch on the supply at the mains outlet, and then operate the mains switch on the unit. The switch will illuminate if power is present, which means that the unit is in standby mode.

4 Bluetooth Operation
The radio requires an audio signal from a Bluetooth device such as a smartphone, tablet, laptop or PC. If your device is already paired with an audio device such as headphones or a hands-free headset you may have to un-pair it first.
Please refer to your device’s instructions to place the unit in scan mode to scan for
Bluetooth devices. With your device in scan mode, turn the volume control up by about one-third, switch the radio on to standby mode at the power inlet, and then turn on using the front panel control.
You should hear ‘Bluetooth Mode’ from the radio, and the device named ‘YET-M1’ should appear in the list of available devices on your Bluetooth device. Select ‘YET-M1’ to pair with it and, if prompted, enter ‘0000’ as the code. You should then hear ‘Paired’ from the radio.
Play some audio from your device and you should hear it through the radio. After pairing for the first time the two devices should pair automatically when you power up the radio unless you actively disconnect, or un-pair it from your device.
If you have difficulty pairing you may have to turn off the radio at the front panel then turn on again to initiate the pairing process, and reset your device to scan mode.
The range of the Bluetooth receiver in the radio is about 10 metres. Outside this range you may experience drop-outs, especially if you are in another room, although reception is good throughout an average family-sized house.

5 Care and Cleaning
5.1
Positioning the Radio
Do not allow this product to be exposed to water, steam or sand. Do not leave your radio where excessive heat could cause damage such as in a parked car or in a conservatory where the heat from the sun can build up even though the outside temperature may not seem too high. Do not position the radio close to a radiator or other type of heater.
Your radio should not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, should be placed on the radio.
It is recommended to operate the product such that there is a minimum distance
(10cm recommended) to adjacent objects in order to ensure good ventilation. The ventilation of the product should not be restricted by covering it, its ventilation openings or heatsink with items such as newspapers, tablecloths, curtains etc.
No naked flame sources such as lighted candles should be placed on or near the product.
Do not place this product in an area which receives direct sunlight, as this can cause fading to the finish.
5.2
Cleaning
Your radio will only need cleaning from time to time with a soft duster or lint-free cloth. Splashes and other marks can be wiped with a damp cloth.
Under no circumstances use household cleaning products, solvents or cleaners as they are liable to damage the finish. Do not use silicone based polishes.
Your radio has been sealed with a modern synthetic varnish and polished with furniture wax, which provides a long-tasting durable protection. The wax finish can be refreshed with energetic buffing. Occasionally apply a thin coat of wax and buff to a high sheen, but avoid frequent over-waxing as the wax layers can build up trapping fine dirt and dust which dimishes the appearance.

8 History
The Kolster-Brandes LR10FM AC mains valve radio was originally made in 1955 by Kolster-Brandes Ltd based in
Foots Cray, Sidcup, a suburb of London. The set is housed in a plywood case, and was coated in a toffeecoloured paint or varnish.
The control knobs (left to right) were originally: on/off and tone, volume, tuning, and waveband selection. The radio was capable of receiving AM and FM wavebands.
This model came to us in a very poor state. The carcass was broken in several places.
When the paint/varnish was stripped back the outer veneer, while not of great quality, had suffered severe water damage and was chipped in several places. The case was repaired, a new central moulding fabricated and fitted, and coated with a modern varnish. Although the veneers on this case are not of the highest quality, they nevertheless are extremely attractive once the full figuring is exposed.
Internally, the valve radio components were stripped out, but the tuning mechanism and display was left in place. The proprietary CIALCO PSU, Power Amplifier and Tone
Control PCB circuitry was installed, together with a high-performance 6.5", full range, dual concentric 50W loudspeaker.
A replacement back panel to meet modern regulations completed the upgrade.
There is a mains switch on the rear, and the front panel controls have been assigned as follows (left-to-right): a combination on/off volume control, bass, tuning mechanism control (decorative only), treble.
