Notes on Batteries
• Do not attempt to charge dry batteries.

be generated if the positive and negative
terminals accidentally come into contact
with metallic objects.
• If you are not going to use the unit for a
long time, remove the batteries to avoid
damage from battery leakage or corrosion.
When to replace the batteries
When the batteries become weak, the
power indicator light dims, or sound
becomes distorted or noisy. Replace the
batteries with new ones as soon as possible.

the display monitor.
• To prevent your ears from being

3
Put on the headphones.
Be sure to put the right housing (R) on
your right ear and the left housing (L)
on your left ear.
4
Start playback.
5
Turn the VOL control dial to adjust
the volume.
If the infrared sensors of the headphones
are covered by your hands when
adjusting the volume, the attenuate
function will be activated and volume
cannot be adjusted. To adjust the
volume, move closer to the transmitter
of the monitor, or orient the infrared
emitters towards the transmitter of the
monitor.
Sound is automatically attenuated if
noise increases
— Attenuate function
If the infrared rays are obstructed, or
the headphones are used outside their
effective range, noise will increase and
sound will diminish. To avoid potential
ear damage as a result of noise, this
function attenuates any sound in the
headphones. Sound is auto-matically
restored when you move nearer to the
transmitter or remove the obstruction.
Selecting the audio channel
You can select the audio channel with the
CH1/CH2 switch to avoid interference
when using the cordless headphones with
other AV equipment. Select the audio
channel according to the Mobile Monitor
XVM-F65 setting of "WireLess Headphone."
After listening to the programmes
Take off the headphones, and then turn
1
off the power (Noise may occur if you
turn off the monitor before taking off the
headphones).
