Battery operation using rechargeable batteries - included (also see page 24)

1. Remove the battery cover on the back of the unit by pushing the battery door in slightly and then downwards in the direction of the arrows in the diagram.

2. Slide the switch inside the battery compartment to the NiMH/NiCad position.

3. Insert three 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 on the back of the radio. The radio is designed to be used with Nickel Metal Hydride (NiMH) or Nickel Cadmium (NiCad) rechargeable batteries.

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 batteries are charging. Batteries will be fully charged in around 7 hours. The battery light shows a steady green light when the battery charging is complete.

• Important: when using rechargeable batteries the battery switch must be placed in the NiMH/NiCad position. Batteries will only be charged when the radio is switched off and connected to the AC adaptor.

• When the batteries are exhausted, the battery 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.

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 alkaline batteries

(also see page 24)

1. Remove the battery cover on the back of the unit by pushing the battery door in slightly and then downwards in the direction of the arrows in the diagram.

2. Slide the switch inside the battery compartment to the Alkaline position.

3. Insert three 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 on the back of the radio. 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 battery 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 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 solarDAB 2 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.

Using the AC adaptor

1. Insert the adaptor plug into the DC in socket on the right hand side of your radio.

2. Plug the adaptor into a standard 13A 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.

Using solar power

Important - The radio does not need to be switched on in order

for the solar panel to operate.

1. In order to recharge your solarDAB radio's batteries using solar power, position the radio so that its integral solar panel receives direct sunlight. The more sunlight that falls on the solar panel - the more electricity it can generate to power the radio.

2. The solar indicator should be used as a positioning aid to achieve the greatest output from the solar panel.

3. The brightness of the solar indicator shows the level of solar energy reaching the solar panel.

4. Adjust the position of the radio so as to achieve maximum brightness of the solar indicator.

NOTE: Best performance of the solar panel will be achieved when the sun is directly overhead, and the sunlight is unobstructed by clouds, foliage, curtains, and the like. In certain situations and poorer light conditions, the solar panel may not be effective and should not be relied upon as the primary energy source for standard usage. The solar panel is designed as a supplementary energy source which under suitable light conditions is able to contribute up to 100% of the radio's energy requirement.

The solar panel will only deliver power to the radio, or charge the batteries under natural sunlight. It will not deliver charge in artiﬁ cial light.

Do NOT attempt to charge the batteries by placing the solar panel directly under any kind of sun-lamp. This will cause irreversible damage to the radio and may damage the casing.

Operating your radio - DAB

1. Carefully extend the telescopic aerial.

2. Press the On/Off button to switch on your radio. The display will show 'Welcome to DAB'.

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.

4. During the scanning process, the lower line of the display shows a bar-graph indicating progress of the scan.

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 'No DAB station'.

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 the Auto Tune button to repeat the scan.

Note: Radio station name and frequency displays shown in this user guide may differ from those that you see on your radio. Broadcasters may change radio station names that are transmitted, and the frequencies used for DAB and FM radio stations may not be the same in all parts of the country.

A Few Words about Batteries…

Your Roberts solarDAB 2 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 rechargeable batteries (included) or alkaline 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 (to

the left as viewed from the back of the radio). 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 (to the left as viewed from the back of the radio).

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

NiMH/NiCad position (to the right as viewed from the back of the radio). Your radio is designed to use Nickel-Metal-Hydride or Nickel Cadmium 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 solarDAB 2 radio uses a range of methods to ensure correct and safe charging of Rechargeable Nickel-Metal-Hydride or Nickel Cadmium 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 be able to power your radio for up to 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.

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/NiCad position. Install the batteries arranging them as shown on the back of the radio. Plug the mains adaptor into a mains socket and then into the radio. 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 5 and 8 hours depending on the battery capacity and their initial state of charge).

25

If you use the radio powered from the batteries, the battery light will be off until the batteries are exhausted. The battery 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 thoughtfully.

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.

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 rear of your radio.
