Setting up the 500K
Before using the 500K, you may need to adjust the length of the
acousc coil. To do so, simply use a pair of pliers to unscrew the
earphone speaker and the acousc coil (B) and take out the coil.
Using a pair of scissors, cut the coil to the desired length. We
recommend cung no more than 1cm at a me. Insert the metal
adaptor and connect the two piece of the coil. Then, push the coil
back into the screw mouth and screw the coil back into the speak-
er base.
Note: Please check the acousc coil is to your desired length
before cung.
You can also choose to use a contour earpiece (C1) or a canal p
earpiece (C2). These earpieces will form to the shape of your ear
allowing for beer t and greater comfort. In order to use these
earpieces, simply remove the silicon earpiece (C) and replace with
the contour or canal p earpiece.
To begin using your 500K, select which ear you prefer to wear it
on. If desired, aach the le or right contour earpiece. Place the
acousc coil ear wrap (A1) over your ear and insert the earpiece
into your ear. The earpiece should t snugly. Aach the clip (B)
to the back of your clothing. Many prefer to aach it on the back
of the collar.
The PTT switch (D) aaches using the clip (F) to your preferred
posion. It should be posioned with the microphone hole (E)
facing your mouth.
The coiled wire (H) should fall from the answer/end call buon
and drape close to your body. The coiled wire can be worn
underneath clothing for added discreon. Finally, the adaptor (I)
aached to the answer/end call buon should be plugged into the
headset jack of your communicaon device.

It is dangerous to operate a vehicle while using a mobile phone.
Please follow local regulaons on driving and cell phone use.
Two-way radios: To connect to your radio and begin communicaons,

nished speaking, release the buon to end transmission. You DO
NOT need to press the PTT to receive incoming communicaons.
There is no need to speak at high volumes as the microphone is
