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.

A Few Words about Batteries…

Your Roberts Play Duo radio has been designed to use a choice of power sources. You may plug it into the mains using the supplied highefﬁ ciency adaptor, or for listening away from the mains you may use either alkaline or rechargeable batteries. We do not recommend the use of carbon-zinc or zinc-chloride batteries.

It is very important that you read the advice and warnings given below.

1) Whichever type of batteries you choose to use, it is very important that the battery selection switch under the cover is set to the correct type.

a. If no batteries are ﬁ tted, then set the switch to the Alkaline position.

This position minimises the power consumption when the radio is powered from the mains.

b. If Alkaline batteries are ﬁ tted, then set the switch to the Alkaline

position.

c. If Rechargeable batteries are ﬁ tted, then set the switch to the

NiMH position. Your radio is designed to use Nickel-Metal-Hydride rechargeable batteries. No other type of rechargeable battery should be used in the radio.

2) NEVER mix old and new Alkaline batteries. The old batteries may suffer damage and leak which will damage your radio and whatever the radio is standing on.

3) NEVER mix old and new Rechargeable batteries. This may result in unreliable charging and shortened battery life. Never mix Rechargeable batteries of different types or capacities even if they are new.

4) NEVER mix Alkaline and Rechargeable batteries. The recharging of Alkaline batteries can be very dangerous.

Rechargeable batteries

Your Play Duo radio uses a range of methods to ensure correct and safe charging of Rechargeable Nickel-Metal-Hydride batteries. These work to protect your batteries from excessive charge and discharge. These protections can only work properly if the advice above is followed. In particular, the radio will not be able to correctly charge batteries if they are a mixture of different brands, or different ages, or different capacities.

We recommend that all the rechargeable batteries used in your radio are bought together as a set. They should always be charged together and discharged together and not “borrowed” from time to time for other applications. This will ensure that they give their optimum performance in your radio.

We recommend that the rechargeable batteries that you use should be from a quality brand, and should be of at least 2500mAh capacity. Batteries of this capacity should power your radio for between 15 and 20 hours depending upon the volume of the radio, whether DAB or FM mode is used (DAB mode uses slightly less power than FM), and also depending on the condition of the batteries. Higher capacity batteries are available and will give longer life, but will generally be more expensive.

Before you ﬁ rst install a new set of rechargeable batteries into your radio you should ﬁ rst make sure that the battery type switch beneath the battery cover is in the NiMH position. Install the batteries arranging them as shown inside the battery compartment. Plug the mains adaptor into the radio and then into the mains socket. While the batteries are charging the charge indicator should show a ﬂ ashing green light. When the batteries are fully charged the indicator will stop ﬂ ashing and will show a steady green light. The time taken to charge the batteries will depend on how much charging they require. New batteries may be partly charged when ﬁ rst ﬁ tted, but it is normal for a set of batteries to take several hours to charge fully (this can be between 3 and 7 hours depending on the battery capacity and their initial state of charge).

Page 26

Your radio will display a message at the end of the charging process. If the charging is successful, or if the batteries are nearly fully charged, the display will show "Battery Full".

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.

If you use the radio powered from the batteries, the charge/low battery indicator light will be off until the batteries are exhausted. The charge/ low battery indicator light will then show red for a short while before the radio switches itself off. It does this in order that the batteries are not excessively discharged. This would otherwise damage the batteries and shorten their life.

If you use the radio powered from the mains with rechargeable batteries ﬁ tted, the charging process is suspended until you switch off the radio. When you switch off the radio using its On/Off button charging will then resume. If the batteries have already been charged then they will only charge for a few more minutes before the charge indicator stops ﬂ ashing.

If you only listen to your radio for short periods, you do not need to connect your radio to the mains to charge the batteries every time that you use it. However, if the radio is not to be used for a few weeks, then we recommend that the batteries are fully charged (charge light shows steady green) before the radio is put to one side.

If you intend not to use your radio for some months, then we recommend that the batteries are removed and put away, keeping them in a cool place out of reach of children, away from moisture and such that no metal object can contact the battery terminals.

With care, rechargeable batteries can last a long time and can operate for many hundreds of charge and discharge cycles. When your rechargeable batteries can no longer power your radio adequately, please dispose of them responsibly using a local battery recycling facility.

To avoid danger and risk of injury, please follow these guide lines

Improper use of batteries may result in leakage of ﬂ uid, overheating or explosion. Battery ﬂ uid is corrosive and may also be toxic. Battery ﬂ uid can cause skin burns, can damage the eyes, and can be harmful if swallowed.

1. Keep batteries out of the reach of children.

2. Do not heat, open, puncture, mutilate or dispose of batteries by burning.

3. Do not mix different battery types or old and new batteries. Always replace all the batteries at the same time.

4. Do not carry or store batteries such that metal objects may contact the end caps.

5. Remove batteries from the radio if they are worn out or if you are storing it for a long time.

6. Remove old or worn out batteries promptly, and recycle or dispose of them according to the regulations applicable to your location.

7. If a battery does leak, remove all batteries from the product, taking care to avoid directly touching the leaked ﬂ uid. If the ﬂ uid contacts skin or clothes wash with water immediately. Before inserting new batteries, thoroughly clean the battery compartment with a damp paper towel, or follow the battery manufacturer’s advice for clean up.

General

Do not allow this radio 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 where the heat from the sun can build up even though the outside temperature may not seem too high. It is recommended that the DAB band be used wherever possible as better results in terms of quality and freedom from interference will usually be obtained than on the FM band.

The name plate is located on the back of your radio.
