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 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 switch, then press and release the

switch. The printer will print a “self test” receipt

If the self test receipt is printed, the DC power is ok

Press switch and wait until all LED’s are off

Plug the AC adaptor into the printer. Press ; 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.
