Cleaning
Do not use harsh or abrasive detergents for cleaning.
Clean the Bird Digital Power Meter and its display with a soft cloth dampened
with mild detergent and water only. Clean sensors with a dry cleaning solvent
that leaves no residue.
Battery Maintenance
Charging Batteries
Fully charged batteries provide about 20 hours of continuous operation with the
Bird WPS, 50 hours with other sensors. Charging time is typically 5 hours using
the AC adapter. The batteries charge whenever the DPM is connected to AC or
DC power sources, using either the AC Mains adapter or the automobile
cigarette lighter adapter. When the external adapter is connected, the battery
level indicator will blink until the battery is fully charged. When using the
internal batteries, the indicator will be on continuously and the black bar will
show the battery change remaining. The unit will charge with its power turned
either on or off.
Note: For optimum battery life, only charge the batteries after
the battery level indicator empties completely and begins to blink.
Prolonging Battery Life
To prolong battery life and optimize the accuracy of battery charge displays:
Charge the battery while the DPM is plugged into external power
through the AC adapter.
Charge it fully before turning on.
The battery charges whether the DPM is off or in use, but the battery
charges faster while the DPM is off.
