Single chime tone rings on NHX-50M every 6 seconds, and a call-in LED blinks slowly every 2 seconds. 2. Press TONE-OFF button to silence tone. The LED above is lit. 3. Go to the Sub station. Press CANCEL button to reset.
5. OPERATIONS on NHX-50M At NHX-50M • Placing Call At NHX-50M At site To call a Bedside Sub station; 1. Press a Sub selector button. The red LED is steadily lit. 2. Lift handset and communicate, voice actuated. OR Press TALK button to talk, and release to listen. 3. At conclusion, replace handset, or press OFF button. At Zone light; At Corridor lamp; At Sub station; Not lit. Not lit. Pre-tone sounds, and green TALK LED is lit.Communicate handsfree.
5. OPERATIONS on NHX-50M Call tone & light annunciation (*) Sound & LED time is approximate. Type of calling At NHX-50M Master station • Receiving Routine call Bathroom call (urgent) Cord-out trouble call • Line-off trouble Bedside sub from Trunk Duty station from NHX-80X • While talking Call tone Light Single chime, every 6 sec. Single chime, every 2 sec. Single chime, every 0.5 sec.
6. TECHNICAL PRECAUTIONS RESET switch The NHX-50M is capable of having as many calls held as there are sub stations. To reply to next call, hang up and lift handset or press TALK button to establish channel. • If calls are of the same level; in the order of time of call, • If calls are of different levels; in the order of urgency. Do not use RESET switch except for initializing or testing the NHX-80X.
6. TECHNICAL PRECAUTIONS Other Operations Fuse replacements (1) On a corridor lamp, the white lamp steadily lit (during routine call) may vary if another bathroom call or cord-out trouble call has been placed in the same trunk. If either fuse blows, there is a problem with the system's power or wiring. Turn power switch on NHX-80X off, and call the installing dealer immediately. The cause of the problem must be found and resolved before new fuses are installed, restoring the system to normal operation.
