6TECHNICAL PRECAUTIONS

Temperatures

NHX-80X and NHX-50M are rated to operate at temperatures 10˚C~49˚C(50˚F~120˚F).

Duty Station Operation

At NHR-SP, sub station call-in is annunciated by tone & LED, which are the same as on NHX-50M.

•The TONE-OFF button silences tone, but CALL LED remains lit. When the NHX-50M begins communication, both tone and LED are deactivated.

•90 seconds after the call tone is muted, it will ring again. Press TONE-OFF button, and it will no longer ring (tone will resume when another sub calls).

Call Holding

Every Routine call is held electronically at bedside sub station, and will be automatically connected when handset is lifted or TALK button is pressed at the NHX-50M. To reset the call, press CANCEL button on the Sub station. When a Bathroom call & Cord-out trouble call is activated, the LED will remain on even after the NHX-50M has answered. The call must be reset at the calling site.
