Sidetone Adjustment - Clear-Com RS-601 Instruction Manual

Sidetone Adjustment

10
To adjust the beltpack's "sidetone," or the level of one's own voice in
the headset, insert a small flat-headed screwdriver into the hole labeled
"sidetone" on the back of the beltpack, as shown in Figure 3. Turn the
screwdriver until you can no longer hear any sidetone in the headset.
This is called the "null" setting.
When you turn the screwdriver again, either clockwise or
counterclockwise, the sidetone increases. Adjust the sidetone so that it
is somewhere in the mid-range of possible settings, at a level that feels
comfortable to you.
The inability to null or set the sidetone level could indicate a problem
with the overall intercom system, such as lack of terminations or
multiple terminations. A malfunctioning headset could also be the
cause.
NOTE: Do not force the sidetone adjustment control past its stop
points as this will damage it.
