Do not use a charger not approved by Extech for use with the
APEX 2
series.
Use of an unapproved charger could damage the ba
ttery pack or the printer
and will void the warranty.
The battery terminals are well recessed inside the printer. Do not allow them
to contact conductive material since this may create a short circuit which
could cause injury or start a fire.
When
using the wall mounted charger ensure the socket outlet is close to
the printer and easily accessible during the battery recharging process.
Either switch the socket off (if supplied with a socket switch) or pull out the
charger from the socket or disconne

that the battery is
charg
ing
.

The battery
f
ast
-
charge is initiated each time the power adapter is
connected to the
printer
.

The fast
-
charge controller checks the battery’s voltage and temperature
before the
sta
rt of the fast recharge process. If the battery voltage or the temperature
exceeds
t
he fast
-
charge limits, the charger defaults to tric
kle charge at C/10 or 70mA rate
.

4.2.2 Important Notes on Replacing Batteries

Check for the correct Extech
battery
part number
and
use
only that part for
the
new
battery
.
Risk of explosion if battery
is replaced by an incorrect type
.
Follow
instructions in Section
4.5
to dispose
of
used batteries

4.3
Verifying Battery Charge State
It is
strongly recommend
ed that
the
printer
be tested
before
it is
retur
ned
to Extech.
Follow
these steps to identi
fy and correct any battery power problem. These
steps
will help
determine
if
the fault is with the printer
or
with
some other part of
the
system.
To test the AC adaptor:

U
se a multimeter and measure th
e output
voltage
.
The o
utput should be
10
VDC
.


Press t
he <
ON/OFF
> switch and wait until
all LEDs are off


Insert the AC adaptor plug into the printer. If the amber LED
switches
on, the battery
is not fully charged
, however
the charge circuit is functioning
correctly
.

The AC power portion of the circuit appea
rs
OK
.
To test the DC power:

Disconnect the AC Adapter
after
the battery
has been allowed to charge for approx. 5
minutes
.

P
ress and hold the <FEED> switch, press and release the <
ON/OFF
> switch and
then
release the

The printer will print
a “self test” receipt
.

If the self test receipt is printed, the DC power is
OK
.
To test if the battery is accepting charge:

Press
the
<
ON/OFF
>
switch
and wait until
all
LED’s
are off
.


illuminate
and
switch off
after
approx. 20 seconds
.

As long as
the amber LED is
ON

ing
circuit is
OK.
At the end of a
18
0 minute charge cycle the LED will
switch
off.
4.4
Battery and Safety Informat
ion
The printer is powered by a
7
.4V
Li
-
Ion
battery cartridge.

Charging time
for
the printer is approximately
3.0
hours
.

Remove
the
battery
from the
printer
before
storing the p
rinter for long periods of
time
.

The ba
ttery storage temperature is 40°F to 104
°F
(4
°
C to 40
°
C). Do not store a fully
charged battery at temperatures greater than 104
°
F (40
°
C) for long periods of time
–
the battery may permanently lose charge capacity
.

The recommended temperature for charging is 68°F (20°C) to 77°F (25°C).

Be sure to
use a fully charged battery before long or battery intensive printing
sessions. Certain operations (for example, printing receipts with
many
bar codes and
graphics) drain the battery more quickly than others
.

Dispose
of battery
according to local regulati
ons.
Do not throw in trash
.
Do not disassemble, short circuit, heat above 80°C, or incinerate. The battery
may explode
.
