Let’s start at the top of the RANGE section.
ALARM turns on whenever the signal is very low or when you have lost TX lock
on the signal. This forces you to recognize that signal is about to be or has
been lost and you must take action to maintain or restore the audio link.
The MODE SELECT switch has 3 positions.
BEEP TONE during which a continuous beeping takes place; the higher the
tone’s pitch the closer the range.
The beep sound is not recorded on the tape recorder, nor is any indication of
the signal level status recorded.
NOTE The beep tone can only be stopped by switching to
OFF or to ALARM ONLY settings.
ALARM ONLY produces a continuous tone to warn that an out-of-range situation
is likely to or has occurred.
5.Range
The RANGE section is the one you have to
watchmost closely.
The RANGE LEDs warn you that the DSS signal
is getting low and audio will be lost unless you
reorient the agent or move the RX closer to the
agent.
Remember, with digital spread spectrum, there
is no in-between zone.
Audio is present and perfect, or it’s gone!
