Tip In many cases, the antenna tripod can be left
unopened, propped up in the side pocket of the
MTU-TXC canvas case. The antenna can receive satellite
signals even if the MTU-TXC is wrapped in a protective
tarpauline. (Just make sure the top of the antenna
remains level.)
If you must stretch the cable in order to position the
antenna, prevent damage to the connectors by
providing strain relief at each cable end. Tape the cable
to the tripod and the instrument handle so that there is
some slack at each connector.
Grounding the MTU-TXC
Warning To prevent damage to the instrument, always
connect a ground electrode to the
GND
terminal
first, before making any other connections.
To ground the MTU-TXC:
1. If necessary, remove 2–2.5cm of insulation from
the end of a grounding wire, and twist the strands
tightly together.
2. Unscrew the
GND
terminal on the MTU-TXC until it
stops.
3. Thread the twisted strands of the cable through the
hole in the shaft of the terminal, and wrap the free
end clockwise around the shaft. If your cable is very
thick, you may have to cut some of the strands at
the insulation in order to fit the wire through the
hole in the shaft.
4. Tighten the terminal securely.
5. Connect the other end of the cable to a suitable
ground.
Protecting the CompactFlash card
slot
The MTU-TXC has a slot to accept a CompactFlash (CF)
card. The CF card fits into a slot in the front of the
MTU-TXC, protected by a small watertight cover.
The card slot is intended for future use; no card is
shipped or used in operating the unit. However, it is
