Setting up the HEINE mPack UNPLUGGED
®
Fitting the 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 brightness control to the
mPack UNPLUGGED.
on
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.)
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).
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 automatically 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. 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 com-
plete. 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.
The battery will not be charged at the same time during
"direct operation".
LED display
Charging
During charging the LEDs operate sequentially, in use they remain
switched on. If all LEDs are out, the charging process is complete
and the battery is fully charged.
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 LED is flashing, you should charge the mPack
UNPLUGGED. If all the LEDs are out, the battery is fully discharged.

Maintenance
EN50 UNPLUGGED and power supply does not require regular
maintenance.
The power supply must not be opened. (Risk of electrical shock).
Li-Polymer batteries can be replaced in mPack UNPLUGGED,
please read the chapter "changing the battery".
Changing the battery
In the course of time, batteries gradually wear out and require longer
charging times; this is normal. If you charge the batteries regularly
and notice a shortening of the operating time or an extension of the
charging time, it is probably time to replace them. The new Li-Pol
battery can be inserted simply by opening the lid of the mPack
UNPLUGGED.
Use only original HEINE Li-Pol rechargeable batteries.
Isolate the mPack by removing it from the charger cradle or by
unplugging the UNPLUGGED mains transformer. Unscrew the eight
screws in the lid of the mPack UNPLUGGED with the screwdriver
supplied and remove the lid, which contains the Li-Pol battery. Make
sure that no metal objects such as screws fall into the unit. Protect
the electronics from electrostatic discharge (ESD), by avoiding
