Keypad
17.1 Introduction
The PRS-CSNKP Numeric Keypad is used in
combination with a basic or remote call station. The call
station provides the microphone and press-to-talk key,
while the numeric keypad can be used for user access,
zone and zone group selection. The numeric keypad
works together with call station keypads for
pre-configured actions. The built-in LCD provides
feedback to the user.
17.2 Compatibility
The PRS-CSNKP can be used with the (new) PRS-CSR
remote call station or the PRS-CSRK remote call station
kit, but not with the (old) LBB4438/00 or LBB4439/00
remote call station (kit). It also works with the
LBB4430/00 or LBB4433/00 call station (kit).
