PROBLEM
Weak Reception
Abnormal White Noise
Crackling in Headphone
Clicking sound
No sound
PROBABLE CAUSE AND SOLUTION
Probable cause is a weak battery. Check battery condition using
voltmeter. Check battery in SimulScope. Recharge, if necessary.
Replace a single headphone battery to test the system. Best reception
is achieved when the infrared diodes on the face of the SimulScope are
pointing directly at the small window in the middle of the Heartman Infrared
Headphone label. Light colored walls will reflect infrared energy so that
direct line of sight contact between the headphone and the SimulScope is
not always necessary. Dark blue or black walls will absorb infrared energy
and cause weak reception if direct contact between the headphone is
not maintained. Pointing the face of the SimulScope toward a mirror will
increase reception.
See Weak Reception above and Florescent light interference below.

Volume on SimulScope may be too high. Reduce volume and click
should disappear.
1. Headphone may be facing in wrong direction. Headphone label
should be facing away from the user. Please keep fingers
away from the label when not in use.
2. If the room has a black or dark blue wall, it will absorb infrared
energy.
3. Be sure VOL controls on SimulScope and headphone are turned up
sufficiently.
4. Heartman Infrared Headphone battery may be depleted.
Replace the 9V battery if necessary.
