Battery operation using alkaline batteries
(also see page 24)
1. Remove the battery cover on the back of the unit by pushing the
catches in the direction shown.
2. Slide the switch inside the battery compartment to the Alkaline position.
3. Insert four LR6 (AA size) alkaline batteries into the spaces in the
compartment. Take care to ensure all batteries are inserted with the
correct polarity as shown inside the battery compartment. Then replace
the battery cover.
• Important: when using alkaline batteries the battery switch must
be placed in the alkaline position. Failure to do so could result
in serious damage to the batteries or radio.
• When the batteries are exhausted, the charge/low battery indicator
will show red for a short while. The radio will then switch itself off. It
may not be possible to switch the radio back on until the batteries are
replaced, or until the radio is connected to the mains adaptor.
• If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.
• We would recommend for economy that the Play Duo is used via the
AC adaptor whenever possible with battery operation for occasional or
stand-by use only. If extended listening using batteries is anticipated,
then the use of rechargeable batteries is recommended.
IMPORTANT: The batteries should not be exposed to excessive heat
such as sunshine, fire or the like.After use, disposable batteries should
if possible be taken to a suitable recycling centre. On no account
should batteries be disposed of by incineration.

Battery operation using rechargeable batteries
(also see page 24)
The first few times that you charge a new set of batteries, you may find that the charge and play times are very short. Normal operation
should be achieved after 3 or 4 charge - discharge cycles.
Batteries are only charged while the radio is connected to the mains supply via its adaptor and it is switched off using the On/Off button.
1. Remove the battery cover on the back of the unit by pushing the
catches in the direction shown.
2. Slide the switch inside the battery compartment to the NiMH
position.
3. Insert four Rechargeable LR6 (AAsize) batteries into the spaces in the
compartment. Take care to ensure all batteries are inserted with the
correct polarity as shown inside the battery compartment. The radio is
designed to be used with Nickel Metal Hydride (NiMH) rechargeable
batteries. Then replace the battery cover.
4. Plug the mains adaptor into your radio and then plug the adaptor into
the mains.
5. The Charge light will flash green indicating that the batteries are
charging. Batteries will be fully charged in around 3 - 7 hours depending
on their capacity. The charge light shows a steady green light when
the battery charging is complete. The display will show "Battery Full".
6. Under some conditions the charging indicator light may switch off after
flashing only briefly. This may happen if the batteries are already freshly
charged, or if the radio detects that you may be attempting to recharge
alkaline batteries. In these cases the charging will be stopped.
If the charge process stops after only a short while this may be due
to a faulty battery. In this case the display will show "Battery Fail" and
the battery number 1-4, corresponding to the numbering printed inside
the battery cover.
If this happens, try charging the batteries a second time by removing
and reconnecting the AC power adaptor. If the message is repeated,
then it is likely that the batteries are old and should be replaced.
• Important: when using rechargeable batteries the battery switch
must be placed in the NiMH position. Batteries will only be charged
when the radio is switched off and connected to the AC adaptor.
• When the batteries are exhausted, the charge/low battery indicator
light will show red for a short while. The radio will then switch itself off.
It may not be possible to switch the radio back on until the batteries
are recharged, or until the radio is connected to the mains adaptor.
• If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.

Note: You should never attempt deliberately to recharge alkaline batteries
in the radio. Attempted recharging of alkaline batteries can be dangerous.
IMPORTANT: The batteries should not be exposed to excessive heat
such as sunshine, fire or the like. After use, disposable batteries should
if possible be taken to a suitable recycling centre. On no account
should batteries be disposed of by incineration.
Lock switch
The Lock switch is used to prevent unintentional operation of your radio.
1. Set the Lock switch located on the back of your radio to the 'Lock'
position (up) . The power and all other buttons will be disabled, this will
prevent accidental operation when your radio is packed in a suitcase
or travel bag.
2. To release the lock, slide the Lock switch down to the 'Unlock'
position (down).
Service
Using the AC adaptor
1. Place your radio on a flat surface.
2. Insert the adaptor plug into the DC In socket located on the left hand
side of your radio.
3. Plug the adaptor into a standard mains socket outlet. Whenever the
adaptor is plugged in to the radio and switched on at the mains the
batteries are automatically disconnected. If the adaptor is plugged in to
the radio but not switched on then the radio will run from the batteries
if fitted.
The AC adaptor should be disconnected from the mains supply and
the radio when not in use.
IMPORTANT: The mains adaptor is used as the means of connecting the
radio to the mains supply. The mains socket used for the radio must remain
accessible during normal use. In order to disconnect the radio from the
mains completely, the mains adaptor should be removed from the mains
socket outlet completely.

Operating your radio - DAB
1. Carefully extend the telescopic aerial fully.
2. Press and release the On / Off button to switch on your radio. The
display will show 'Welcome to Digital Radio' for a few seconds and
then the display will show '0:00'.
3. If this is the first time the radio is used a scan of the Band III DAB
channels will be carried out. If the radio has been used before the last
used station will be selected. After a short time the current time will
appear on the display.
4. During the scanning process, as new stations are detected the station
counter on the right hand side of the display will increase and stations
will be added to the list. The lower line of the display shows a bar-graph
indicating progress of the autotune.
5. When the scanning is completed the first station (in numeric-alpha
order 0...9...A....Z) will be selected.
6. If the station list is still empty after the scan your radio will display
'Service Not Available'.
7. If no signals are found it may be necessary to relocate your radio to
a position giving better reception. Then either switch your radio off
and on again, or press and release the Auto Tune button to repeat
the scan.
