The XD1+ has a simple tri-indicator graphical interface which is used to communicate on-device warnings, sampling modes, battery indication and a device heartbeat. From Left to right:
- Indicator 1: STEL Warning.
- Indicator 2: TWA Warning.
- Indicator 3: Battery indication/heartbeat.
Audio Alarm
The built-in alarm sounder provides audio warnings at 85 db in conjunction with the illuminated icon interface to alert users to on- device alarm threshold breaches.
Power Button
A single power and function button is used on the XD1+ for device power on/off, alarm acknowledgement and device self-test.
Power On
When the XD1+ is powered on, all indicators will illuminate white:
Self-Test
On initial power up, the XD1+ will perform a self-test sequence indicated by a sequential blue flash of each indicator. This is followed by a ‘pass’ indication of flashing green indicators and sounder confirmation:
If the self-test fails or identifies any faults during the routine, flashing red indicators will be indicated:
Power Off
When the XD1+ is powered off, all indicators will illuminate white incrementally before the XD1+ powers down:
STEL Alarm
When a STEL alarm is triggered, flashing amber warning indicator 1 will be illuminated when the STEL threshold is breached:
TWA Alarm
When a TWA alarm is triggered, flashing red warning indicator 2 will be illuminated when the TWA threshold is breached:
Battery Indicator
The battery indicator will flash green intermittently (3 seconds) to indicate a power status between 100 and 70%:
The battery indicator will flash amber intermittently (3 seconds) to indicate a power status between 69 and 40%:
The battery indicator will flash red intermittently (3 seconds) to indicate a power status of 39% or lower. When the XD1+ reaches a battery level of < 10%, a red warning will flash every second:
Heartbeat
- Heartbeat: The XD1+ heartbeat is indicated via the intermittent flashing (3 seconds) of the battery indicator:
