The next generation of self-contained keyless entry door latches features AlSentis HSS Touch Technology. The Bauer EM-D is an FMVSS206 approved 2-pin safety latch touchpad lock for motorhome applications. This new technology is absolutely the best touch technology on the market today, which does not need to be “awakened.” It requires less power, resulting in longer battery life, and can distinguish human touch from liquids. The keypad is embossed with the name “Alsentis HSS” to indicate this technology is present. The EM-D allows the owner to program a 4-digit PIN for security and convenience. The button labeled “1|2” is the same button whether the number 1 or 2 is desired. Please note this handle uses Touch Technology. The buttons are activated by touch and do not require pressing the buttons. Touch the button and lift finger from button for proper code entry. The EM-D uses the Dealer Key System.
