2. When correctly connected, the first LED indicates the charging status:
- Quickly flashing orange = battery charging
- Slowly flashing green = battery fully charged
- Slowly flashing red = batteries failed; cannot be recharged
New or completely discharged batteries take approximately two (2) hours to fully
recharge.
3. When the LED indicates the batteries are fully charged (slowly flashing green), the
unit is ready for operation.
NOTE: When the unit is not in use, it should be connected to the charger to ensure full
battery power is later available. The internal charging circuit prevents over-charging
and provides a continuous maintenance charge when required by the batteries.
Storage
Even when powered off, the unit slowly discharges the batteries over time. Before
storing the unit for extended periods (over 4 weeks), remove the battery pack from the
unit. The battery pack will eventually self-discharge and require recharging before use.
Replace batteries according to the instructions in the Getting Started section, and as
shown in Figure 2.
Disposal
Batteries are recyclable. Do not incinerate or expose to open flames.
Dispose of batteries according to local, state, and federal regulations.
SENSOR
The Heated Pentode™ sensor is a precise device that, in conjunction with the
advanced circuit, provides the superior performance of this unit.
The sensor is a consumable element and will eventually require replacement. The
circuit continuously compensates for sensor aging to maintain a constant performance
level; sensitivity and response remain the same throughout the life of the sensor.
