menu.
3. Press the MENU LEFT/RIGHT keys to enter the AUDIO
sub menu.
4. Use the MENU UP/DOWN keys to select LSA.
5. Apply a 300 Hz BTSC sound signal with a signal strength
of 60 dBuV (1 mV_rms) to the aerial input (only the left
channel of the stereo signal). Measure the output on pin 22
(R_OUT) of IC7841 with an AC millivoltmeter.
6. Use the MENU LEFT/RIGHT keys to adjust the meter
reading to a minimum value (default LSA value is "7" for
stereo sets, and "0" for mono sets).
7. Press the MENU button to return to the top level SDAM
menu.
8. To ensure the LSA setting is saved:
– Turn the television set 'off' by using the 'POWER'
button on the remote control transmitter or the local
keyboard.
– Disconnect the television set from AC power for at
least ten seconds.
– Reconnect the television set to AC power.
– Turn the television set 'on' by using the 'POWER'
button on the remote control transmitter or the local
keyboard.

3. Press the MENU LEFT/RIGHT keys to enter the AUDIO
sub menu.
4. Use the MENU UP/DOWN keys to select HSA.
5. Apply a 3 kHz BTSC sound signal with a signal strength of
60 dBuV (1 mV_rms) to the aerial input (only the left
channel of the stereo signal). Measure the output on pin 22
(R_OUT) of IC7841 with an AC millivoltmeter.
6. Use the MENU LEFT/RIGHT keys to adjust the meter
reading to a minimum value (default HSA value is "31").
7. Press the MENU button to return to the top level SDAM
menu.
8. To ensure the HSA setting is saved:

button on the remote control transmitter or the local
keyboard.
– Disconnect the television set from AC power for at
least ten seconds.
– Reconnect the television set to AC power.
