TECHNICAL 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).
