Setting up
Fitting the HEINE
®
mPack UNPLUGGED to the instrument
headband:
First remove the rear segment cover of the headband. To do this,
hold the headband in the region of the rear segment cover with
your left hand and pull the segment cover to the right with your
right thumb.
Then fit the mPack UNPLUGGED to the rear part of the headband
by supporting the headband with your left hand and placing the
mPack UNPLUGGED on the headband so that the LEDs are
arranged to the left. The mPack UNPLUGGED will engage securely
with a little light pressure from your left thumb. Connect the bright-
ness control to the mPack UNPLUGGED.
The batteries must be charged before using the mPack UNPLUGGED
for the first time. You can charge the mPack UNPLUGGED either
from the UNPLUGGED plug-in transformer or from the EN50
UNPLUGGED charging station.
When supplied, new batteries are only partially-charged. The mPack
UNPLUGGED must be charged before the instrument is used for
the first time. The LED indicator corresponds to the actual battery
capacity only after a full charge and discharge cycle. (Also applies
when changing the battery.)
Note:
– To enable the LED display of the mPack UNPLUGGED to show
the true battery capacity, the unit must first be completely dis-
charged and then recharged. Switch on the instrument connected
to the mPack UNPLUGGED until the battery is completely dis-
charged, then recharge the mPack UNPLUGGED until charging
is completed. (Also applies when changing the battery).
Wall mounting the HEINE
®
EN50 UNPLUGGED:
Use the four provided screws to fix the mounting bracket to the
wall. Place the EN50 UNPLUGGED on top of the mounting bracket
and fasten with the two top screws.
Operation
Charging via the HEINE
®
EN50 UNPLUGGED (wall-mounted
charger):
Connect the plug-in transformer to a suitable mains outlet (pay
attention to the mains supply voltage). The green LED on the plug-in
transformer will light. The mPack UNPLUGGED can be charged in
charging cradle I or charging cradle II. Using gentle pressure, insert
the mPack UNPLUGGED into the charging cradle until it engages
securely.
Charging cradle I is intended for parking the complete instrument
and for charging the mPack UNPLUGGED. The instrument is auto-
matically switched off as soon as the complete instrument is parked
in charging cradle I. The mPack UNPLUGGED will engage in the
charging cradle with light pressure, thus ensuring safe charging.
After approx. 1 second, the LEDs start to light in sequence. During
charging, the LEDs blink.
(See the “LED display” chapter for further information.) When you
remove the instrument from the charging station and switch it on
with the brightness control, all five LEDs will light if the battery is
fully charged. As the level of charge falls, the LEDs go out in turn.
If the orange LED starts to flash, you should recharge the battery.
Note: You can park the instrument in the charging station at any
time, even after short periods of operation. To increase the working
life of the battery, recharging only occurs if the residual charge is
less than 75%.
Charging by means of the UNPLUGGED power unit:
Please note that charging with the UNPLUGGED mains transformer
is only possible when the brightness control is switched off.
Connect the plug-in transformer to a suitable mains outlet (pay
attention to the mains supply voltage). The green LED on the
plug-in transformer will light. Next connect the cable to the right
or left connector on the mPack UNPLUGGED.
The charging process begins. All LEDs will go out as soon as the
charging process is complete. Disconnect the charger. You can
now switch the instrument on by means of the brightness control.
The following applies to either charging method:
– The charging process is dependent on the residual charge of the
battery and requires a maximum of approximately 2 hours.
– The charging process switches off automatically when the battery
is full, all LEDs go out.
– Overcharging of the battery is not possible.
Direct operation:
Direct operation is possible if there is no capacity in the mPack
UNPLUGGED battery but you want to continue to work with the
instrument. To do this, simply connect the UNPLUGGED plug-in
transformer to the connector on the left or right hand side and
switch the instrument on with the brightness control.
Note: The battery will not be charged at the same time during
“direct operation”.
LED display
Charging
– During charging the LED’s operate sequentially, in use they
remain switched on.
– If all LEDs are out, the charging process is complete and the
battery is fully charged.
– mPack UNPLUGGED up to 2010 behave differently. Up to 2010
the LED are switched on and off in the same way. However, the
number of LED’s illuminated shows the state of charge of the
battery.
Operating the mPack UNPLUGGED
– The number of LEDs illuminated indicates the level of charge in
the battery. The full operating period is achieved when at least
4 LEDs are lit.
– If the orange LED is flashing, you should charge the mPack
UNPLUGGED.
– If all the LEDs are out, the battery is fully discharged.
Servicing and cleaning
– Always disconnect from the mains before cleaning.
– It is possible to wipe with a damp cloth. If a cleanser is used, it
must be approved for use on plastics.
– Disinfectant cleaning can be done using an alcohol-based
surface disinfectant.
– Spray disinfection, soaking or disinfection in a machine is not
permitted.
– Check the function of each unit regularly. Use the units only
when they are functioning correctly.
