Check for the correct Extech part number for the battery and only order
that part for your new battery
!
Caution: Risk of explosion if battery is replaced by an incorrect type.
!
Caution: Dispose of used batteries according to instructions in Section
4.5
4.3 Verifying Battery Charge State:
It is strongly recommended testing your printer before returning to Extech. Follow
these steps to identify and correct any battery power problem that may be
encountered. These will help to identify that the fault is with the printer and not
some other part of your system.
To test the wall mounted charger unit use a multi-meter and measure the
output. Output should be 10VDC
Press the <ON/OFF> switch and wait until all LED’s are off
Insert the line cord into the printer. If the amber LED goes on, the battery is
not fully charged but the charge circuit is functioning.
The AC power portion of the circuit appears ok
Disconnect the charger unit once the battery has charged for 5 minutes.
Press and hold the <FEED> switch, then press and release the <ON/OFF>
switch and then release the <FEED> switch. The printer will print a “self test”
receipt
If the self test receipt is printed, the DC power is ok
Press <ON/OFF> switch and wait until all LED’s are off
Plug the AC adaptor into the printer. Press <ON>; the green LED is
illuminated and after about 20 seconds the LED should go off
If the amber LED is on, this will continue on through this test indicating that
the battery is accepting a charge and that the charge circuit is ok. At the end
of a 100 minute charge cycle the LED will go off.
4.4 Battery and Safety Information:
The THS printer is powered by a 8.4V NiMH battery cartridge and the T by a 6V
NiMH battery cartridge.
Charging time in the printer is approximately 1.5 hours
Take the battery out of printer if storing the printer for long periods of time
The battery 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
Be sure to use a fully charged battery before long or battery intensive
printing sessions. Certain operations (for example, printing receipts with a lot
of bar codes and graphics) drain the battery more quickly than others
Dispose according to your local regulations. Do not throw in the trash.
