Rechargeable Power Unit
A rechargeable power unit (RPU) is also available. A fully-charged
RPU should contain enough power for at least 1,200 breath tests, in
continuous operation. Mains and 12volt DC chargers are available.
When first received, the RPU will not be fully charged.
To fit the RPU, ensure the instrument is switched off, then press the
release catch on the back of the unit and remove the existing power
unit. Now fit the RPU, ensuring the release catch clicks positively
into place. Connect the RPU to the appropriate charger and leave
for about one hour to charge up fully, when the red LED goes out.
IMPORTANT - PLEASE NOTE:
Switch the instrument off before removing and refitting
either the PSU [disposable batteries], or the RPU.
Don’t attempt to recharge the AA cells.
Don’t switch the instrument on while the RPU is charging.
Don’t attempt to recharge the RPU when it is already fully
charged.
Don’t leave the instrument with a flat power pack attached.
This shortens the life of the internal lithium battery which
powers the memory and clock circuits.
Don’t carry either the PSU or the RPU in your pocket. If
the contacts were to short-circuit on a key or coin, serious
burns to your body could result.
