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, ﬁ re 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 ﬁ rst few times that you charge a new set of batteries, you may ﬁ nd 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 (AA size) 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 ﬂ ash 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

ﬂ ashing only brieﬂ y. 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.

Warning: internal battery switch MUST

be set to correct battery type before installing

recommended.

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, ﬁ re 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 ﬂ at 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 ﬁ tted.

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 ﬁ rst 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 ﬁ rst 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.
