Charging the PRO-Diary Battery
The PRO-Diary contains a lithium polymer rechargeable battery. The life of the
battery is very dependent on usage of the unit
– more frequent and longer
questionnaires will be more demanding. However it should be at least 30 days in
commonly expected uses.
Before the Diary can be used
, the user must ensure that it is fully charged.
You may charge it directly from the PC, from a mains power supply or from a
separate USB hub. It will typically take around
3-4 hours
for the PRO-Diary to
be fully charged.
3.1 Charging the Diary from the PC
Connect the Diary to a free USB port of the PC and it will be automatically
charged from the PC. If you connect multiple Diaries to the same PC at the
same time, windows will attempt to find extra drivers. This will generate
windows/warnings which can be safely cancelled. You may only communicate
with a single Diary but as long as your PC is capable of it, several should charge
together.
Note that many PC’s have power saving functions which may shut down the USB
ports after a period of time; this will stop the diary charging until normal operation
is resumed. If you any issues related to charging or battery life, we recommend
using a mains power supply for charging to avoid this issue.
3.2 Charging the Diary using the Mains Power Supply
The PRO-Diary may be recharged using a mains adaptor with a standard USB
power output (the type often used for charging MP3 players or phones). Please
ensure any such adaptor is safety approved to EN60950-1 and EMI standard
EN55022 (also FCC part 15, Class B for the USA).
1.
Select and fit appropriate
ac input
socket adaptor for country of use.
2.
Plug the USB cable from the Diary directly into the USB socket on the
mains power supply adaptor.
3.
The Diary will be automatically charged.
CamNtech can supply a suitable mains power supply if required
– please contact
your local distributor.
3.3 Charging Several Diaries from a USB Hub
A USB extension hub may be more convenient to charge several PRO-Diary
devices at once without requiring a PC to be connected. This hub must be
powered by a separate mains adapter itself. CamNtech have tested the PRO-
Diary with a Belkin 4-Port Hub; other hubs with a separate mains adapter are
also likely to work, but CamNtech have not tested against them.
CamNtech can supply a suitable powered USB Hub if required
– please contact
your local distributor.
