INSTALLATION - Bracket
Youcan install theX-45 on thetop of adash or froman overhead withthe
suppliedbracket. Itcan also be installed inthe dashwith anoptional IDA-
3 or IDA-4 mounting kit. If you use the supplied bracket, you may be
interested in the optional GBSA-1 swivel bracket kit. This converts the X-
45's gimbal bracket to a swivel mount which can be used on the dash or
overheadmounting positions.Installation instructionsfor thein-dash and
swivel mounting kits are supplied with the adapter kits.

POWER CONNECTIONS
The X-45 works from a 12 volt DC system only. For the best results, run
thepowercabledirectlytotheboat’sbattery. Keepthepowercableaway
fromotherboatwiring,especiallytheengine’swires. Thiswillgivethebest
isolation from electrical noise. If the supplied cable is not long enough to
reachthebattery,splice#18gaugeinsulatedwiretoit.Ifyoudoextendthe
powercable,makecertaintoattachthein-linefuseholdersuppliedwiththe
X-45to thebatteryor powersource.This willprotect boththeunit andthe
power cable in the event of a short. Use only a 3-amp fuse.
IMPORTANT!
Do not use this product without a 3-amp fuse wired into the power cable!
Failure to use a 3-amp fuse will void your warranty!
You can also attach the power cable to an accessory or power buss,
however, you may have problems with electrical interference.
This units has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the wires
are attached correctly.
