Status Messages at the Host Monitor
Various status messages related to the telemetry transmitter may
show at the host monitor when there is a problem with the signal or
when the battery is low. The host monitor may be either the central
station or bedside monitor.
The status messages that follow may appear at the host monitor.
Refer to SpO2 Messages at the Host Monitor on page 3-18, for status
messages related to SpO

.
• INTERMITTENT SIGNAL LOSS
Indicates that the patient may be out of antenna range or the
battery is depleted. Return the patient into antenna range. Check
that the battery is functioning properly. A low-priority alarm
occurs after 10 seconds in this condition.
• LOW BATTERY
Indicates the battery is weak. After this message appears, the
battery has approximately one hour of useful life left (depending
on the type of battery used). Install a new battery. A low-priority
alarm occurs if the setup menu’s LOW BAT ON/OFF key is set to
ON.
• SIGNAL INTERFERENCE
Indicates, through the triangle-shaped squelch waveform, that
an interfering signal has been detected. The patient’s signal can
no longer be detected because of interference from a stronger
signal source lasting more than 0.5 seconds. A low priority alarm
occurs whenever this message appears in the waveform zone.
• IS SIGNAL LOSS PERMANENT?
Indicates no radio frequency (RF) signal is detected.
• Do not ignore status messages.
• SpO

data may not show when the INTERMITTENT SIGNAL
LOSS message appears.
• Status messages indicate a problem or condition which
may affect accurate monitoring values.
• Correct any fault before continuing.
