12ICMTxR Green Mode Button Pressing the Green Mode button once will momentarily refresh the display and backlight the ICMTxRWhile the display is still lit, pressing the mode button (green) again will toggle the display between current cylinder pressure and calculated remaining pressure time
13ICMTxR Green Mode Button The remaining pressure time displayed is based on your average breathing rate over the last three minutes.Breathe faster: less time on displayBreathe slower: more time on display
14Continuous Operations Mode ON The Continuous Pressure Mode can only be activated when the system is pressurizedIn Continuous Operations Mode, the life of the batteries in the Receiver will be shortenedThe Continuous Operations Mode will deactivate if a low battery is present
15Continuous Operations Mode ON To activate the Continuous Pressure Mode:Push the top mode button (green) on the ICMTxR Unit and hold button in for 3 seconds.Once LED’s lights come on, release button. Receiver will show air cylinder pressure level.LED lights will stay on to show air cylinder pressure level drop.
16Continuous Operations Mode OFF To deactivate the Continuous Pressure Mode:Push the mode button (green) on the ICMTxR Unit and hold the button in for 3 seconds.LEDs will revert to Automatic Mode showing only air cylinder pressure status at each 25% increment of full cylinder pressure.The Heads-Up Display System will automatically turn itself OFF, approximately 60 seconds after the apparatus is depressurized. (A single red LED light will flash during this time).
17Reset ButtonUpon returning to fresh air, close the cylinder valve completely and release all pressure from the system using the bypass valve. When the pressure falls below 200 psig, turn the device off by pressing the (Yellow) reset button 2 times in rapid succession.The ICMTxR Unit will beep 1 time when the button is pressed once. Pressing the (Yellow) button a second time will then sound three beeps (“bee-bop-bop”) to indicate that the unit is turned off. The lights will also stop flashing.
19Thermal AlarmThis chart shows the ICMTxR Unit thermal alarm activation curve. The thermal alarm sounds if the exposure exceeds the curve.The alarm will self-cancel depending on the severity of conditions. This may occur even though the temperature is above the thermal curve.
