The R250 PRO dual band phone is the first mobile phone to support both GSM phase 2+ technology and the GSM Pro system, which will give the users a unique opportunity to combine the advantages of GSM phones with Private Mobile Radio functionality. Finished in a bright, eye-catching orange or a sober, dark green, R250 PRO is the perfect working tool for outdoor communications in tough environments. Equipped with GORE TEX membranes and rubber gaskets, which protect against water and dust, R250 PRO has a sturdy magnesium frame and rubber moulding which can withstand harsh treatment. The battery contains a unique locking mechanism to ensure it will not separate if the phone should be dropped, and a special sealing agent has been used to stop any moisture entering the phone.With special features like the built-in speakerphone, alert button, built-in vibrating alert and a unique button on the side for quick access to the phone book, this mobile phone is specially designed for the target group's requirements.
