Chapter 5  Setting Up the Unit 
 

The Dose Alarms 

There are two Dose Alarm thresholds: Low 
Dose, for a minor hazard, and High Dose, for 
a severe hazard. 

The optional Vibrator Alarm can be used in 
addition to the audio and visual alarms when 
background noise makes the audio alarm hard 
to hear. 

High Threshold 

There are several indicators for the High Dose 
Alarm Threshold (Figure 8). 

•

 

Visual Enabled

 – The DOSE and 

ALARM indicators and the right LED 
will flash quickly. 

•

 

Audio Enabled

 – The audio will beep 

quickly. 

•

 

Optional Vibrator Enabled

 – The unit 

will vibrate.
