The WLS910 is a wireless handheld keypad which can perform any hardware keypad function. The handheld keypad operates in conjunction with the PC5132 Wireless Receiver. For a complete description of keypad functions, please consult your PC5010 Instruction Manual. Just as there are function keys located on your system’s keypads, there is single-button activation of commmonly-used features from the WLS910 through the number keys [1] to [4]. Together with your installer, you can decide which functions you wish to have accessible from your portable keypad. To activate any one of the four selected functions, press and hold the appropriate key for two seconds. Your installer will indicate each function by marking them on a label applied to the back of the handheld keypad.
