Usage Tips:Lightweight and ergonomic design makes it very comfortable. It is the perfect choice when your remote control is lost or damaged or you want a one. This is a special replacement remote control, not the remote control, but the function is 100% the same as the one, covering all the functions of the remote control. No programming required-just insert the battery (not including the battery), it can be perfectly matched with your device or receiver, the mission distance is longer, and the performance is stable Small and exquisite: easy to hold, small in size, suitable for various Sony brand models, easy to use Specification: Product name: remote control Model: TP7187R Applicable brand: for GRUNDIG Applicable models: for GRUNDIG TP7187R remote control Power supply: 2 AA batteries (not included) Colour: black Material: ABS Package Contents: 1 x remote control Only the above package content, other products are not included.
