6. TECHNICAL PRECAUTIONS
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.
