• [7]: Front panel (see details above)
• [8]: Battery A compartment trapdoor

CAUTION - THE TWO TRAPDOORS SHOULD BE OPENED 
ONLY FOR INSERTING OR REMOVING BATTERIES. THE

.
• [10]: Power/data connector (DC input + RS232 serial port
A). The connector socket is protected by a black rubber 
cap attached to the receiver case. Always keep the 
protection cap on when the connector is not used. This 
cap is a non-polarized one.
IMPORTANT: When you connect a cable to that connector, 
be sure you align the red markings (a red dot on the plug, 
a red line on the socket) before pushing the Lemo plug in. 
Conversely, when it’s time to disconnect the Lemo plug, 
please use the attached metal strap to pull the plug out.
• [11]: 5/8” threaded insert. This part is securely mounted
on a removable plate, thus making up an assembly that 
can be replaced with a UHF module (optional accessory) 
fitted with its own, specific threaded hole and central 
coaxial socket for antenna connection (see Using the UHF 
Kit Option on page 46). 
• [12]: Shock absorber making up a robust protection belt
for the receiver against drops to the ground. The shock 
absorber houses two flaps for access to two card slots and 
to a USB connector. The height mark is also nested in the 
shock absorber. See below.
