Heterodyne Feature - Spectronics Marksman II Série Mode D'emploi

HETERODYNE FEATURE

The Marksman II features heterodyne capability, which converts
the ultrasonic frequencies detected by the instrument to sounds
that can be heard by the human ear. This allows you to more
easily isolate the ultrasonic source.
Simply plug the included headphones into the jack on the right
side of the Marksman II to enable heterodyne capability. Dragging
your finger upwards/downwards on the sensitivity touch pad will
increase/decrease the volume of the headphones.
NOISE-CANCELLING HEADPHONES
Please follow the instructions below when using the
RP-NCH-01 Noise-Cancelling Headphones.
1. Switch on the ultrasonic receiver and plug the headphone con-
nector into the receptacle located on the right side of the
receiver.
2. Plug the opposite connector into the jack located on the bottom
of the left headphone.
3. Turn the headphones on using the switch on the side of the right
headphone. Make sure the red indicator light is lit when the
power switch is in the on position. If the light does not turn on,
the headphones may need to have the batteries replaced. (One
AAA battery is included and pre-installed. The battery chamber
is accessible via the top of the right headphone.)
4. Put on the headphones, adjusting the headpiece as needed so
that the headphones surround each ear with the outer rims
snugly against your head for optimal noise cancellation.
5. Adjust the volume on the receiver according to the noise level in
your environment (using the receiver touchpad), then slowly
increase or decrease the volume on your headphones with the
volume control knob on the headphone cord.
