7 Connecting the Printer
7.1 Voltage Supply
Internal Battery Pack, Charging
The battery pack includes 4 NiMH Mignon (AA) cells
with 1,600 mAh. A temperature sensor monitors the
battery temperature during the charging process. A
bimetal circuit-breaker is integrated to protect against
short circuits and overheating.
The battery is connected with a 7 pin connector (9)
through the window in the battery compartment. The
battery charging voltage is connected through the
polarity protected socket (5). The plug-in power supply
for charging is part of the supplied set. It has a
connection cable with the matching connector plug
attached.
A fully charged 1,600 mAh battery will print up to app.
50 m of thermal paper with normal text.
7.2 Options
Power Management
Whenever the printer does not have data to process, it
will automatically switch to idle mode. In this mode, it
appears to be 100% active and is ready to accept
data.
Power Off
The printer is switched off by holding down the "OFF/
NEXT" button for >3 seconds. It is turned on by
pressing the FEED/ENTER button or by connecting the
charger.
Inserted rechargeable batteries require at least 3
complete charging and discharging cycles in order
to reach their full capacity. Incomplete charging
and discharging cycles during operation will redu-
ce the life span of the battery.
7.3 Charging
The GeBE-FLASH
®
for iOS is equipped with an
intelligent charging circuit without charging current
limiting. The current limiting is ensured through the use
of the power supply that is supplied with the printer.
The charging process is devided into three steps:
Formatting Charge
If the battery is over-discharged, it is first charged with a
low-current formatting charge in order to prevent
damage to the battery. The formatting charge is not
signaled externally. Depending on the status of the
battery, the formatting process can take about 1 to 5
minutes.
Fast Charge
As soon as the battery voltage has exceeded the
operating voltage of the printer, the printer will start a
fast charge. This is signaled through a slow flashing
STATUS LED and a message through the interface.
For empty batteries, the charging process takes about 4
hours.
Trickle Charge
As soon as one of the criteria for disconnecting has
been reached, the printer will switch to a trickle charge.
In this mode, the formatting current flows permanently.
In addition, the fast charge is activated every 8 minutes
for 20 seconds. This is signaled through permanent
lighting of the STATUS LED and a message through the
interface.
Before Installation:
Always disconnect the power in the system !
The use of a charger different from the one
supplied can cause damage to the printer.
The optimum temperature range for charging the
battery is between 20°C and 25°C, allowed range:
0°C to 30°C.
Fully discharged batteries can disturb the charging
in such a way that it breakes in at less than 30
minutes and switches to preservation charge. In this
case please start to charge again by reputting.
