devices included but not limited to methane monitor, radio, mobile phone, GPS, PDA, battery
charger and laptop computers.

The Surface Display with Silent Zone is directly powered from the controller board and requires
no internal battery or charging.
2.3 Alerts
The Surface Display also has 4 LEDS which in the case or a Warning or Danger condition,
indicate which Surface Proximity Modules (another component of the HazardAvert System) are
detecting the Warning or Danger condition.

audible alerts to the operator of a Warning or Danger condition.

The Surface Dislay Unit with Silent Zone should be regularly cleaned to reduce buildup of dust
and dirt.
