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.
