A few words about batteries Rechargeable batteries Your radio has been designed to use a choice of power sources. You may plug it into the mains using the supplied 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. Your radio use a range of methods to ensure correct and safe charging of Rechargeable Nickel-Metal-Hydride batteries.
If you use the radio powered from batteries, the battery light will be off until the batteries are exhausted. The battery light will then show red for a 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 fitted, the charging process is suspended until you switch off the radio.
