2.10 Message Waiting
The NRX4 has a built in LED and neon lamp for message waiting indication. This is
compatible with various PABX systems providing such features. A message waiting
switch is built inside the switch compartment located on the base bottom. This
switch enables the LED to detect two different line reversal signals by selecting switch
position 1 or 2.
For 90V DC or AC message waiting signalling PABX's the neon is used for indication.
Set the position of the switch to off, as the LED is not needed for indication.
The default switch position is OFF.
Please note the compartment door should be replaced when settings completed.
