 To: All harman/kardon Service Centers
 Models: AVR 10/20/25/3250; AVI 100/150/200 
 Subject: Remote Control has stopped working
In the event you receive a complaint about a remote control that has stopped working, perform 
the following tests:
1) Remove the batteries and confirm they are not weak or defective (battery voltage should be 1.4 volts
or more). Replace batteries if necessary; both batteries in remote control should be replaced.
2) Point the remote towards the corresponding receiver/amplifier and confirm the remote control 
functions operate as intended.
3) If Remote Control still doesn’t work:
 Remove batteries, and with an alligator clip lead or other jumper wire, short the positive and  negative
tabs inside the control together. (See drawing) This short will drain any remaining charge from 
the capacitors in the remote control and re-set the microprocessor.
4) Re-insert batteries and test the functions as per item (2) above.
NOTE: This procedure may also work for other h/k model remote controls not listed above.
