important that the watertight cover remain in place to
protect the slot and circuitry.
To replace the card slot cover:
1. Align the ring of the slot cover at right angles to the
length of the cover.
2. Place the bevelled edge of the cover against the
MTU-TXC case and push the cover handle fully into
the case.
3. Turn the cover handle one-quarter turn clockwise to
lock.
Connecting the battery
The MTU-TXC is powered by a 12V DC battery, which
should be fully charged prior to use. (Follow the
instructions provided on the Battery Charging Quick
Reference Guide.)
Newer Phoenix BTU-type batteries are shipped with the
cable ends bolted to the battery terminals; older
batteries were shipped with the cable unattached.
Note Make all other connections, and always a ground
connection, before connecting a battery to the
MTU-TXC.
To connect a BTU-type battery:
1. Examine the battery terminals and clean off any
corrosion that might prevent a good electrical
connection. (Use sandpaper, emory cloth, or a knife
blade to carefully clean the terminals.)
2. If the cable ends are not bolted to the battery
terminals, attach the alligator clamps to the
terminals (red clamp to the positive [+] terminal,
black clamp to the negative [–] terminal).
Ensure
that the connection is secure and of correct
polarity.
Tip On batteries with spade terminals, attach the alligator
clamps so that they grip the edges rather than the flat
surfaces of the terminals. The greater tension from the
clamp springs helps ensure a good connection.
3. Fit the slotted connector to the
EXT BATT
terminal on
the MTU-TXC as described on page 11.
