WM 10 Wireless Audio Module
The WM 10 Wireless Audio Module allows a user to be free of cables that normally
tether them to the detector.
There are two audio options with the Wireless Module; use the internal speaker or
the 1/4-inch headphone socket.
The headphone socket on the WM 10 will work with either the supplied Koss
headphones or third party headphones. Note that the headphone socket uses an
internal mechanical switch, rather than electronically sensing headphones, so the
Wireless Module is compatible with a wider range of third party headphones than
the Headphone Module.
There are 14 frequency channels available to select from within the detector. Change
channels if there is interference, or if you are detecting near someone else using a
WM 10. Ensure that you are each using a different channel.
The WM 10 is powered by an internal Li-ion battery and is recharged via a mini USB
connector.

Waterproof headphones connector
The waterproof headphones connector is an eight pin socket at the back
of the CTX 3030’s control box. It is used to provide audio signals to the
waterproof headphones and the Headphone Module.
If the CTX 3030 is being used without the Headphone Module connected,
use the small screw cap that is stored in the Headphone Module to protect
the waterproof socket from dirt and sand.
