Assembly And Preparation - Nexus Ultima User Manual

ASSEMBLY AND PREPARATION

The Nexus Ultima is supplied ready assembled, with the telescopic stem
retracted. To prepare the Nexus Ultima for use, simply extend the lower
stem section and by using the locking pin underneath fix the two poles in
working position to the desired length. Then tighten the locking collar to
eliminate movement between the two parts of the stem.
By holding the two rubber washers together with the stem joint, slacken the
coil to stem joint bolt slightly and adjust the coil angle to the stem so that,
when holding the Nexus for searching, the coil is parallel to the ground
surface. It is recommended that a small amount of lubricant (WD40) is
applied to the inner sides of the coil attachments for easier assembly.
Tighten the coil bolt by hand. Ensure that the search coil cable is
reasonably tight all the way over the stem, but not strained. Check that the
coil connector plug is fully inserted into the socket on the back panel of the
control box.
The Nexus Ultima is designed to work with 8 AA dry cell alkaline batteries
or rechargeable pack of 8AA batteries. Remove the four cross-head screws
from the base panel of the battery box (the battery box is below the arm
cup at the top of the detector stem). Lift off the cover. Insert the batteries, in
their correct alignments, into the plastic holder and make sure that all the
terminals have a good electrical contact. Locate the battery holder into the
compartment, ensuring the connecting cable is not strained or pinched. Do
not over-tighten the screws.
Connect the headphones to the 6mm jack socket on the battery box. The
Nexus Ultima does not have an internal loudspeaker so headphones are
essential. For any headphones that have a volume control, ensure that this
is set to MAXIMUM and use the Nexus Volume knob to set the volume
level
