Charger
If the recorder is powered by rechargeable
batteries (4 of them are shipped with the
equipment), they should be recharged
immediately after use (24 hours). Use only the
original charger supplied. It consists of an AC
power adapter and the charging unit itself.
Check that the voltage ratings on the nameplate
of the charging unit match those of your local
power line. Connect the cable of the AC power
adapter to the charging unit and plug the AC
power adapter into the wall outlet.
Insert 4 or 2 batteries, observing their polarity.
To charge only 2 batteries, insert them in the
two compartments on the right or on the left.
The batteries take up to 3 hours to recharge.
Once the batteries are inserted, battery symbols
will appear in the charger display where each
symbol corresponds to one of the charger
compartments (Fig. 2). During the charge cycle,
the corresponding bar in the battery symbols
blinks. Note: If the battery symbols and bar do
not light up, only one battery may be inserted or
the batteries are inserted the wrong way round.
When the batteries are charged, the bars are
permanently illuminated. The charging unit now
trickle-charges the battery to compensate for
self-discharging.
The battery temperature is monitored in the
charger. When the temperature is too high, the
bar in the battery symbol is permanently
illuminated and the charger switches to trickle-
charging.
If the batteries are correctly inserted and the
displayed battery symbols show no bars, the
charger has identified a battery problem. The
charging current to the compartment concerned
will be cut off. Remove the battery and discard,
observing the applicable waste disposal
regulations.

CAUTION
•
Equipment damage, risk to patients
•
The charger is not a medical device. It must not
be used in the patient environment .
The contact surface of the NiMH batteries and
of the charger must always be kept clean.
The charger is to be used indoors only and must
be protected against oil, grease, aggressive
detergents and solvents to prevent damage.
If the charger is damaged in any way, e.g. after
a drop or when the mains pins are bent, the
local authorized dealer must be contacted
immediately.
High temperatures affect the charging process.
Ideally, the room temperature should not
exceed 40 °C (104 °F).
After quick charging, please wait for some
minutes before another quick charge.
Otherwise the temperature sensors will not
function correctly.
