This is the first time I'm replacing a multi function handle on a Hyster reach. Question is, is the handle a straight forward plug and play or will I have to recalibrate the handle? If I need to recalibrate the handle would you be so kind as to reply with the recalibration steps please? I'm also guessing I'll need a code to enter the service menu so if you could pass that on to me I would be very grateful. Thanks
