IR TRANSMITTER ADJUSTMENTS
(DCR-TRV130)
(DCR-TRV130)
Adjust using the IR receiver jig (J-6082-383-A).
Note:
If the distance between the IR receiver jig and the camcorder is
below 1m, cover the LASER LINK emitter with a ND filter. (For
example, when the distance is 30cm to 50cm, cover the LASER
LINK emitter with a ND filter 1.0.)
