Setting up the 500K
Before using the 500K, you may need to adjust the length of the
acoustic coil. To do so, simply use a pair of pliers to unscrew the
earphone speaker and the acoustic coil (B) and take out the coil.
Using a pair of scissors, cut the coil to the desired length. We
recommend cutting no more than 1cm at a time. 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 acoustic coil is to your desired length
before cutting.
You can also choose to use a contour earpiece (C1) or a canal tip
earpiece (C2). These earpieces will form to the shape of your ear
allowing for better fit and greater comfort. In order to use these
earpieces, simply remove the silicon earpiece (C) and replace with
the contour or canal tip earpiece.
To begin using your 500K, select which ear you prefer to wear it
on. If desired, attach the left or right contour earpiece. Place the
acoustic coil ear wrap (A1) over your ear and insert the earpiece
into your ear. The earpiece should fit snugly. Attach the clip (B)
to the back of your clothing. Many prefer to attach it on the back
of the collar.
The PTT switch (D) attaches using the clip (F) to your preferred
position. It should be positioned with the microphone hole (E)
facing your mouth.
The coiled wire (H) should fall from the answer/end call button
and drape close to your body. The coiled wire can be worn
underneath clothing for added discretion. Finally, the adaptor (I)
attached to the answer/end call button should be plugged into the
headset jack of your communication device.
Use and Care
Mobile phones: To answer a call, simply press the answer/end call
button once. To hang up a call, press the answer/end call button
again. There is no need to speak loudly, as the microphone is
sensitive enough to pick up your normal speaking voice. To pause or
play audio, press the answer/end call button once. To skip tracks,
double click the button
.
The volume can be adjusted by turning
volume dial (G).
It is dangerous to operate a vehicle while using a mobile phone.
Please follow local regulations on driving and cell phone use.
Two-way radios: To connect to your radio and begin communications,
push and hold the PTT (D) button while you speak. When you are
finished speaking, release the button to end transmission. You DO
NOT need to press the PTT to receive incoming communications.
There is no need to speak at high volumes as the microphone is
sensitive enough to pick up your normal speaking voice. The volume
can be adjusted with the volume dial (G).
