5.3 Charging the dBadge2
Battery charging is via an intelligent combined docking station and 3-way charger (part
number 207078B) required to download the dBadge2 memory and/or to charge the internal
Nickel Metal Hydride (NiMH) batteries.
It consists of the docking station itself and a wall mounted power supply (part number PC18)
which requires an appropriate plug adaptor for the country of use (a selection is supplied) and
connects to either of the 12V connectors on the rear of the docking station.
The ‘docking pocket’ with the USB symbol is specifically reserved for downloading data
(but will also charge a dBadge2). For more information please refer to Section 12 but note that
to download, the docking station must be powered.
Ensure the PC18 power supply is connected and the supply is switched on; a red LED on the
docking station will illuminate to show that power is on. When a dBadge2 is placed in any
pocket a ‘fast charge’ will automatically start. The dBadge2 will display the battery charging
status, i.e. ‘charging’ or ‘full’ and the LED will flash red. It will also show the percentage of
battery charge and an estimation of battery usage time. Note: the estimation of usage time is
based on the load conditions i.e. if octave band frequency analysis has been selected this will
reduce the estimated run time from the maximum of approximately 35 hours. After
approximately 20 seconds the display will blank and the red LED on the dBadge2 will continue
to flash. Pressing either the left hand ‘L’ or right hand ‘R’ key (or tilting the docking station) will
wake the display for a further 20 seconds to check progress. Once fully charged the LED will
turn blue.
A charge time from empty to full is approximately 6
hours which will allow a run of circa 35 hours. Note this
is with no audio recording or octave band analysis and
assumes that the display is off for 95% of the time.
Shorter charge times will result in reduced pro-rata run
times.
Estimated battery life is 1000 cycles. The NiMH battery
is integral to the dBadge2 and must only be replaced by
a qualified person.
