Connectors and Accessories
The receiver has a standard 3.5mm headphone jack that accepts any
mono or stereo earphones or headphones. Schonstedt also supplies
headphones as an optional accessory. The receiver automatically
detects the insertion of the headphones or earphones and routes the
audio signals to them, silencing the internal speaker.
The receiver comes fitted with a rubber plug to protect it from water
and dust ingress. It is recommended to keep the rubber plug inserted in
the earphone jack when earphones are not being used. The receiver also
comes standard with a belt holster for hands-free carrying.
The receiver is shipped factory ready to detect sondes or other devices, such as inspection
cameras, that transmit at 512 Hz; however, the sondes themselves are optional accessories
also available through Schonstedt.
Battery Replacement
The Rex receiver is powered by one 9-volt alkaline disposable battery. The battery is located
in the handle of the instrument and can be accessed by turning the screw counterclockwise.
To remove the battery, simply tilt the unit so that the handle is pointing down, and the
battery will slide out. When replacing the battery, look at the outside of the battery door for the
proper battery orientation. As a safety measure the unit will not turn on if the battery is not
inserted correctly. You should never have to force the battery door closed. If the battery does
not seem to be going in all the way, remove the battery, reverse its orientation and then replace
it.
