A Few Words about Batteries… Rechargeable batteries Your Roberts Expression radio has been designed to use a choice of power sources. You may plug it into the mains using the supplied highefficiency 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 Expression radio uses a range of methods to ensure correct and safe charging of Rechargeable Nickel-Metal-Hydride batteries.
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.
Display backlight 1. When using the radio powered from batteries, the display backlight will be switched on for approximately 12 seconds when any button is pressed. 2. When your radio is powered by the AC mains using the supplied mains adaptor the display backlight will always be on whenever the radio is switched on. USB socket for software upgrade A USB socket is provided at the rear of your radio for service use only to permit the possibility of updates to the internal software in the future.
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.
