1Introduction
Thank you for buying one of our beautiful radios! We hope it will provide hours of trouble-
free, high quality entertainment.
Your radio is easy to set up and use and, with a few simple precautions, will continue to
look good and operate efficiently for many years.
2Power 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.
If your radio is equipped with rechargeable
batteries, this is also the batteries will now
be charging. Charge the batteries for at
least 2 hours before running on batteries
alone.
If the switch fails to illuminate, first check that the mains supply is present, then disconnect
the supply and check the fuse in the mains plug and the unit inlet connector. In the unlikely
event that any of the fuses have blown the unit may be faulty.
WARNING
ELECTRIC SHOCK RISK
This unit contains no user serviceable parts.
Under no circumstances remove the rear panel with the mains
voltage connected.

4Bluetooth 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.

5Care 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.

8History
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 toffee-
coloured 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.
