Other Operations
(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.
(2) A pullcord call in a bathroom illuminates the master
call indicator lamp on the panel.
If another call has been placed from a bathroom
nearby, the lamp will look dimmer on both units.
Fuse replacements
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.
Two UL Listed replacement fuses (250V AC, 3A) are
included in the NHX-80X.
