Care and Maintenance of your ACS In-Ear Monitors

It is important to read these notes to ensure longevity 
of your custom monitors. Cleaning them regularly and 
paying close attention to their maintenance is vital 
to ensure their continued performance. We offer full 
cleaning and reconditioning services for your monitors 
so please don’t hesitate to call if your monitors need 
attention.
NEVER remove your monitors by pulling on the cable.

Cleaning and Storage

Use a moist cloth or sterile wipe to clean the silicone moulds and cables. Always 
hold your cables by the plug, rather than the earpiece, to clean. DO NOT 
immerse any part of the monitors in any liquid. If they get wet, place them in 
a warm, dry atmosphere and use dehumidifier (silicate crystals) to 
remove any moisture. Be careful not to tangle the cables and always 
store your monitors in the case provided when not in use.

Visually inspect the sound ports on each earpiece to check 
that no wax, skin debris or dirt has penetrated the 
tubes. Use the wire loop pick provided to 
carefully remove any matter.

NOTE : The most common cause of failure 
is due to ingression of ear wax into the 
sound tubes. This is easily prevented by 
regular checks and cleaning.

Cable Types / Cable Management

ACS Monitors are fitted with different cable options. The 
cable can exit over the top of the ear and round 
the back of the head (fig 5), or from the lower 
part of the ear like the cables fitted to most 
conventional types of headphones and 
earphones(fig 6). If your cables exit at the top 
of the ear, the cable can be secured at the 
back of the head by moving the slider fitted to 
the cable in an upward direction (fig 7).

Fitting

Your monitors are handed, the right earpiece being identified with a red detail and 
the left earpiece with a blue detail. From a comfort and acoustic perspective, it is 
important that they are fitted correctly to provide a good seal of the ear.

Begin by placing the tip of the monitor into 
your ear canals whilst at the same time making 
sure that the top part of the mould is located 
under the flap at the top of the ear (fig 2). It is 
sometimes easier to use both hands when fitting 
the earpieces (fig 3). 

Gently press the mould until it feels located and 
secure (fig 4). Use the comfort cream to help the 
fitting initially. Spread a small amount around the 
ear canal tip, being careful to avoid the sound 
tubes.

We want you to be delighted with your ACS hearing 
protectors. If, for any reason, you experience difficulties
