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:
Remove the batteries and confirm they are not weak or defective (battery voltage should be 1.4 volts
1)
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
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.
