4.2.2 IMPORTANT NOTES ON REPLACING BATTERIES
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 AC adaptor 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 AC adaptor plug into the printer. If the amber LED goes on, the
battery is not fully charged but the charging circuit is functioning.
The AC power portion of the circuit appears ok
Disconnect the AC Adapter once the battery has charged for
approximately 5 minutes.
Press and hold the <FEED> switch, then press and release the <ON/OFF>
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 when in RS232 mode and after approximately 1
1
/2 minutes, 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 180 minute charge cycle the amber LED will go off.
