A Few Words about Batteries… Rechargeable 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 high- effi 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.

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

first 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).
